abstract = {Abstract  Constant true strain rate simple compression tests
were conducted on annealed, polycrystalline samples of α-brass and
MP35N, and the evolution of the true stress (σ)-true strain (ε)
response was documented. From these data, the strain hardening rate
was numerically computed, normalized with shear modulus (G), and
plotted against both (σ − σ 0)/G (σ0 being the initial yield
strength of the alloy) and ε. Such normalized plots for α-brass
and MP35N were found to be almost identical to each other, and revealed
four distinct stages of strain hardening: stage A, with a steadily
decreasing strain hardening rate up to a true strain of about −0.08;
stage B, with an almost constant strain hardening rate up to a true
strain of about −0.2; stage C, with a steadily decreasing strain
hardening rate up to a true strain of about −0.55; and a final
stage D, again with an almost constant strain hardening rate. Optical
microscopy and transmission electron microscopy (TEM) were performed
on deformed samples. The results suggested that stage A corresponded
to stage III strain hardening (dynamic recovery) of higher stacking
fault energy (SFE) fcc metals such as copper. The onset of stage
B correlated with the first observation of deformation twins in the
microstructure. Further straining in stage B was found to produce
clusters of parallel twins in an increasing number of grains. Stage
C correlated with the development of severe inhomogeneity of deformation
within most grains, and with the development of significant misorientation
between the twin/matrix interface and the {111} plane in the matrix
of the grain, i.e., the matrix/twin interface lost coherency with
continued deformation. Stage D correlated with extensive formation
of secondary twins that resulted in twin intersections in many grains.
Early in stage D, some strain localization in the form of shear bands
was observed. Although formation of these shear bands had no detectable
effect on the macroscopic strain hardening rate, it did correlated
with a marked change in texture evolution. Based on these experimental
observations, we have developed and presented a physical description
of the microstructural phenomena responsible for the various strain
hardening stages observed in low SFE fcc alloys.},

abstract = {Abstract  The digital image correlation (DIC) technique
is successfully applied across multiple length scales through the
generation of a suitable speckle pattern at each size scale. For
microscale measurements, a random speckle pattern of paint is created
with a fine point airbrush. Nanoscale displacement resolution is
achieved with a speckle pattern formed by solution deposition of
fluorescent silica nanoparticles. When excited, the particles fluoresce
and form a speckle pattern that can be imaged with an optical microscope.
Displacements are measured on the surface and on an interior plane
of transparent polymer samples with the different speckle patterns.
Rigid body translation calibrations and uniaxial tension experiments
establish a surface displacement resolution of 1 μm over a
56 mm scale field of view for the airbrushed samples and 17 nm
over a 100100 μm scale field of view for samples with the fluorescent
nanoparticle speckle. To demonstrate the capabilities of the method,
we characterize the internal deformation fields generated around
silica microspheres embedded in an elastomer under tensile loading.
The DIC technique enables measurement of complex deformation fields
with nanoscale precision over relatively large areas, making it of
particular relevance to materials that possess multiple length scales.},

abstract = {Deformation behavior of polysynthetically-twinned lamellar γ-TiAl
+ α2-Ti3Al single crystals has been analyzed using a three-dimensional,
isothermal, rate-dependent, large-strain, crystal-plasticity based
materials constitutive model. Within the model it is assumed that
plastic deformation parallel to the γ-TiAl/α2-Ti3Al lamellar boundaries
is controlled by the softer γ-TiAl phase while deformation which
contains a component normal to these boundaries is dominated by the
harder α2-Ti3Al phase. The parameters appearing in the crystal-plasticity
materials constitutive relations are assessed using the available
experimental information pertaining to the active slip systems, their
deformation resistances and hardening and rate behavior of the two
constitutive phases both in their single-crystalline and in polysynthetically-twinned
lamellar forms. The constitutive relations are implemented in a Vectorized
User Material Subroutine (VUMAT) of the commercial finite element
program Abaqus/Explicit within which the material state is integrated
during loading using an explicit Euler-forward formulation. The results
obtained suggest that the adopted crystal-plasticity model and the
parameters assessed in the present work account quite well for the
observed room-temperature deformation behavior of polysynthetically-twinned
lamellar γ-TiAl + α2-Ti3Al single crystals.},

abstract = {Abstract&nbsp;&nbsp;Using recently developed methods for application
of a nano-scale random pattern having high contrast during SEM imaging,
baseline full-field thermal deformation experiments have been performed
successfully in an FEI Quanta SEM using 2D-DIC methods. Employing
a specially redesigned commercial heating plate and control system,
with modified specimen attachment procedures to minimize unwanted
image motions, recently developed distortion correction procedures
were shown to be effective in removing both drift and spatial distortion
fields under thermal heating. 2D-DIC results from heating experiments
up to 125°C on an aluminum specimen indicate that (a) the fully
corrected displacement components have nearly random variability
and a standard deviation of 0.02&nbsp;pixels (≈25&nbsp;nm at 200×
and ≈0.5&nbsp;nm at 10,000×) in each displacement component and
(b) the unbiased measured strain fields have a standard deviation
≈150 × 10−6 and a mean value that is in good agreement with
independent measurements, confirming that the SEM-DIC based method
can be used for both micro-scale and nano-scale thermal strain measurements.},

abstract = {Abstract&nbsp;&nbsp;A metallographic study has been made of the microstructures
produced by room temperature deformation of 0.6mm thick commercially
pure titanium sheet metal in uniaxial, plane strain and biaxial tension.
Deformation twinning becomes increasingly important as the deformation
mode changes from uniaxial through plane strain to equibiaxial tension,
and is more significant for strain transverse to the rolling direction
than for strain in the longitudinal direction. In uniaxial tension,
1122 twins are dominant in longitudinal straining, while 1012 twins
dominate in transverse straining. In plane strain and equibiaxial
straining, 1012 twinning is suppressed and largely replaced by 1122
twinning. The observed changes in twin occurrence and type are attributed
to the interaction of the imposed stress system and the crystallographic
texture of the rolled sheet, which alters the distribution of the
grain basal-plane poles with respect to the operative stress axes.
In uniaxial tension parallel to the longitudinal direction, twins
favored by ‘c’ axis compression are produced, while in the transverse
direction twins favored by ‘c’ axis tension appear. In plane
strain and biaxial tension the dominant stress is through-thickness
compression, which produces twins favored by ‘c’ axis compression
in nearly all cases. The alterations in twin orientation and numbers
are associated with changes in stress-strain behavior. As twin volume
fraction increases and twins are aligned more closely to the principal
stress axis, the instantaneous work-hardening rate tends to stabilize
at a nearly constant value over a large strain range.},

V in the solution treated and aged (4 h at 815 K) condition, and
in the as-welded condition. Some aged specimens were tested after
pre-straining. Creep stresses ranged from 40 to 90 pct of the aged
material yield strength. Results showed that creep was of the primary
or transient kind in all cases, and was much greater in welded than
in aged material. In general, pre-strains reduced creep, although
a strain larger than 10-3 was needed to do this at the highest creep
stress. Activation areas A* were between 10 and 20 b2, and thus were
similar to tensile results on titanium and its alloys. The microstructural
rationale applied to Ti-5 Al-2.5 Sn in earlier work, based on the
character of dislocation sources, proved successful in understanding
the effects of prestrain in this work.},

twinning in the strain-hardening behavior of high purity, polycrystalline

strain rate tests were conducted on this material in simple compression,
plane-strain compression and simple shear, and the true stress ([sigma])-true
strain ([var epsilon]) responses were documented. From the measured
data, the strain hardening rates were numerically computed, normalized
by the shear modulus (G), and plotted against both normalized stress
and [var epsilon]. These normalized strain hardening plots exhibited
three distinct stages of strain hardening that were similar to those
observed in previous studies on low stacking fault energy fcc metals
(e.g. 70/30 brass) in which deformation twinning has been known to
play an important role. Optical microscopy and Orientation imaging
microscopy were conducted on samples deformed to different strain
levels in the various deformation paths. It was found that the onset
of deformation twinning correlated with a sudden increase in strain
hardening rate in compression tests. The falling strain hardening
rate correlated with saturation in the twin volume fraction. In shear
testing a much lower rate of strain hardening was found, at all strains,
and this correlated with a lower density of deformation twinning.},

the effect of deformation twinning on the mechanical response of

employed in conjunction with optical microscopy and quasi-static
compression testing to obtain insight into the deformation mechanisms.
Hardness measurements revealed that the newly formed deformation
twins were harder than the matrix. This observation is perhaps the
first experimental evidence for the Basinski mechanism for hardening
associated with twinning, arising from the transition of glissile
dislocations to a sessile configuration upon the lattice reorientation
by twinning shear. This work also provided direct evidence for two
competing effects of deformation twinning on the overall stress-strain
response: (1) hardening via both a reduction of the effective slip
length (Hall-Petch effect) and an increase in the hardness of twinned
regions (Basinski mechanism) and (2) softening due to the lattice
reorientation of the twinned regions.},

a layer by layer movement through twinning dislocations as proposed
for twinning dislocation theories. The sidewise propagation and thickening
of a twin lamella proceeds in a step-wise manner with lattice match
planes being the coherent boundaries between the matrix and twins.
This model predicts that twinning in h.c.p. lattices can occur at
a high velocity close to the sound speed, which is impossible according
to twinning dislocation theories. The proposed mechanism is also
consistent with other observations such as lack of critical-resolved-shear-stress
for twinning, emissary dislocations, and insensitivity to temperature.
Dislocation reactions may be involved in twinning although they are,
at high stresses, not required.},

over the temperature range of 4.2-650<35>K. Using the thermally activated
approach, values of the usual activation parameters were determined
and found to be in good agreement with those reported previously
for polycrystalline titanium with total interstitial contents ranging
from 0.05 to 1 at.% Oeq. This agreement supports the earlier conclusion
that the deformation kinetics in polycrystalline titanium are associated
with slip on the first-order prism planes. Also, the present data
support the earlier proposal that the rate controlling dislocation
mechanism during the low temperature deformation of titanium is thermally
activated overcoming of interstitial solute obstacles. Comparison
of the single crystal results with those on polycrystals yielded
a value of 5 for the Taylor factor relating resolved shear stress
to the tensile stress in titanium polycrystals.},

beyond diffuse necking were obtained with a novel strain-mapping
technique based on digital image correlation (DIC). Key microstructural
features (including defects) in each of these three metallurgical
zones were examined to explore the material influence on the plastic
deformation and failure behavior. For weld fusion zones with minimal
defects, diffuse necking was found to begin at 6 pct strain and continue
up to 55 to 80 pct strain. The flow stresses of the weld fusion zones
were at least twice those of the base material, and fracture strains
exceeded 100 pct for both materials. The heat-affected zones exhibited
a range of complex deformation behaviors, as expected from their
microstructural variety. Only those fusion zones with substantial
defects (e.g., shrinkage voids, cracks, and contaminants) failed
prematurely by edge cracking, as signaled by their highly irregular
strain maps.},

to understand and quantify the effects of seven parameters on fatigue
crack incubation: applied displacement, load ratio, particle modulus,
the number of initially active slip systems, the relative crystallographic
misorientation at the grain boundary, the particle aspect ratio,
and the normalized particle size. The simulations clearly showed
that the applied displacement is the most influential parameter.
In most cases, particles were found to be more significant than bicrystal
boundaries for incubation. The number of initially active slip systems,
the particle aspect ratio, and the normalized particle size showed
some influences on fatigue incubation. The particle modulus was the
least influential parameter.},

the evolution of crystallographic texture and the anisotropic stress-strain

and slip inside twinned regions were all considered as contributing
mechanisms for the plastic strain in the model. This was accomplished
by treating the dominant twin systems in a given crystal as independent
grains once the total twin volume fraction in that crystal reached
a predetermined saturation value. The newly formed grains were allowed
to independently undergo further slip and the concomitant lattice
rotation, but further twinning was prohibited. New descriptions have
been established for slip and twin hardening and the complex coupling
between them. Good predictions were obtained for the overall anisotropic
stress-strain response and texture evolution in three different monotonic
deformation paths on annealed, initially textured samples of high
purity [alpha]-titanium.},

mechanical behavior arises from a competition between alternate defect

importance of accurate atomistic modeling of these defects, going
beyond simple interatomic energy models. Recent results from both
experiments and theory are summarized by discussing specific examples

h.c.p. lattice of a-Ti can be described by a sessile splitting on
the prism plane and on the first order pyramidal plane simultaneously
and that slip can proceed after its transformation into a glissile
configuration on the prism plane. The strengthening by interstitial
solutes O, N, C is explained by their impeding role in these sessile-glissile
transformations. A good agreement between the theoretical temperature
dependences of the effective stress for different interstitial content
and the experimental values can be reached if the effect of impurities
on the stacking fault energies is also taken into account. The similarity
between the role of screw dislocations in the low temperature deformation
of h.c.p. metals with more slip systems operating and of b.c.c. metals
is stressed.},
