Morphology and crystallography of twins in the martensite in Ti-Ni and Ti-Pd shape memory alloys are reviewed on the basis of recent electron microscopy observations. It has been confirmed that there are five and three twinning modes in Ti-Ni and Ti-Pd martensites, respectively. The morphology and crystallography of newly found deformation twin in Ti-Ni martensite are briefly reported. The irrational nature of Type II twin boundary has been clarified by high resolution electron microscopy observations in edge-on state. There are neither ledge nor step structures at the irrational boundary.
