Abstract

The boundary structure of the 〈011〉 Type II, {111-} Type I, 011 Type I, (100) compound and (001) compound twins in the B19′ martensite in the Ti-Ni shape memory alloy was observed in the edge-on state by high resolution electron microscopy (HREM). The lattice images of the Type I and the compound twins exhibit the well-defined crystallographic features of those boundaries. Lattice image of the 〈011〉 Type II twin taken from the unique η1 axis suggests that neither ledge nor step structures are present at the irrational boundary.
