Effect of phase transformation on texture formation in Ti-base alloys

Variant selection during the β→α phase transformation in rolled Ti-64 alloy has been studied by comparing model and experimental textures. It has been shown that the β→α phase transformation during heat treatment of Ti-64 alloy can proceed without or with preferred selection of orientation relationship variants depending on the heat treatment employed. In the later case, the number of variants may be different in different texture components. Possible reasons for variant selection are discussed.
