摘要：

The boundary structure of the [011] Type II, {11(1) over bar} 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 eta(1) axis suggests that neither ledge nor step structures are present at the irrational boundary.
