β¦ Synopsis
We analyze the stability of laminated microstructure for martensitic crystals that undergo cubic to trigonal, orthorhombic to triclinic, and trigonal to monoclinic transformations. We show that the microstructure is unique and stable for all laminates except when the lattice parameters satisfy certain identities.

Martensitic transformation was investigated for Ti-rich Ti-Ni gas-atomized powders as a function of powder size. The large powders clearly exhibit multiple martensitic transformations on both cooling from austenite to martensite and vice versa. With increasing powder size, the minor martensitic tran
