Stress induced martensitic transformation in metastable β Ti-5Al-5Mo-5V-3Cr alloy: Triggering stress and interaction with deformation bands

Abstract

Structures of a coarse-grained β-Ti alloy were studied after compression. Stress-induced martensitic transformation (SIMT) and slip were dominant. TEM revealed the geometrical relationships between α” and the compressive load, enabling calculation of the SIMT triggering stress. α” cut by deformation bands created a unique orderly arrangement of α” blocks.
