Abstract

Variation in morphology of α phase with aging temperature in a Ti-15V-3Cr-3Sn-3Al alloy has been investigated. At higher temperatures (723 K to approximately 933 K), precipitation of α phase starts from β grain boundaries. The morphology of α phase within the β grain is lath-shape. On the other hand, at lower temperatures (573 K to approximately 673 K), aggregates of twin-related fine α plates form uniformly within β grains. Crystallography of α phase does not change with aging temperature, the Burgers orientation relationship and a near {111}β habit plane are commonly observed. It is considered that, at lower temperatures, α phase nucleates preferentially at the athermal ω phase formed during quenching to room temperature after the solution treatment.
