Abstract

Twins in the martensite in Ti-Ni and Ti-Pd shape memory alloys of near-equiatomic composition were investigated by conventional and high resolution transmission electron microscopy. The specimens were prepared using the recrystallization texture of cold-drawn rod and the parent-martensite lattice correspondences. The following twinning modes were reconfirmed in the B19′ martensite: 〈001〉 type II twinning, a lattice invariant shear; {111} type I twinning which is morphologically divided into a deformation twin, a variant accommodation twin, and a lattice invariant shear; (100) and (001) compound twinnings; and {011} type I twinning, also a lattice invariant shear and a conjugate mode of the 〈011〉 type II twinning.
