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