Spin-glass nature of tweed precursors in martensitic transformations.
Many displacive solid-solid transformations, despite being first order, show pronounced precursor effects, such as the mesoscopic, micron-scale, tweed'' pattern seen in shape-memory alloys. We modelExpand

Degenerate Blume-Emery-Griffiths model for the martensitic transformation.
A generalization of the Blume-Emery-Griffiths model is introduced in which an entropy stabilization of the high-temperature phase is controlled by a degeneracy parameter p>1. The model describes aExpand
