Dynamic tensile test of Ti-5Mo-5V-2Cr-3Al under the condition of solution treatment was studied, and the martensitic phase transformation induced by the stress during the tensile load, strain-hardening, grain rotation deformation and crack formation, meeting and failure were also studied. The results show that the stress induces the martensitic phase transformation, and the martensite pieces rotate orientedly and are swallowed each other under the external stress to form the macroplastic deformation. When loading stress continuously, the slips will arise in these grains. The slip bands and martensite pieces cross to form slip steps. With the slip intensifying, the grains are stretched and rotate, which results to the stress concentration and crack occurs gradually.
