Martin Diehl e3a64ae4ff don't fit close to 0K
cryogenic temperatures are normally not of interest, avoid considering
the strongly curved region below 80K in the fit gives probably better
extrapolation properties for T>300K

Martin Diehl ba16ea21a0 avoid overfitting
there are only 3 data points for C_13, with one close to 0K. Leave this
point out and fit only a 1st order polynomial

Martin Diehl eb0fca9222 generic examples
might help some users to make the connection between old an new names,
good to have examples anyways

Martin Diehl 8f0a16e654 fine tuning parameters
more stable, still physically reasonable

Martin Diehl 1883919b3c working configuration
simulations are not particular stable, but trends are ok and values seem
reasonable

Martin Diehl 7e4a374c9e new material parameters
- austenitic steel AISI304
- SAE1050 after quenching to martensite

I don't know how the old set of elastic constants for martenstite
(originally coming from 10.1088/0965-0393/23/4/045005) was derived,
but it is hard to believe that the elastic behavior can be that strongly
modified by a heat treatment.

not clear for which material they have been introduced, according to
T.R. Bieler and P. Eisenlohr they are typicall not active in any
