MiS Preprint Repository
We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Symmetry and reversibility of martensitic transformations
Kaushik Bhattacharya, Sergio Conti, Giovanni Zanzotto and Johannes ZimmerAbstract
Martensitic phase transformations observed in many crystalline solids are of interest for a variety of technological and scientific reasons. They come in two widely different classes. In steels, the transformation microstructure induced by quenching (fast cooling) remains essentially unchanged upon subsequent loading or heating. The transformation is not reversible. In shape-memory alloys, on the contrary, the microstructures formed on cooling are easily manipulated by loads and disappear upon reheating. The transformation is reversible or `thermoelastic'. This paper provides a simple explanation for this difference on the basis of crystal symmetry.
