Martin Diehl 976cfd501a thermal expansion coefficients for SiC
this material was the initial motivation for adding fourth order
polynomials, but I could not find a reliable source for the graphs send
to damask@mpie.de. It seems that the CTE levels off for even higher
temperature which calls for a higher order polynomial

I'm not able to reproduce the results from https://doi.org/10.1016/j.actamat.2016.07.032,
but these parameters give results that are qualitatively ok

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
2022-02-13 14:57:01 +01:00
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 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.
