英文摘要Evolution of deformation mechanisms and mechanical properties of Ti-3Al-5Mo-4.5 V alloy with different beta phase stability have been systematically investigated. beta phase stability alteration is achieved through quenching temperature variation from dual alpha + beta field (700 degrees C) to single beta field (880 degrees C). Tensile tests at ambient temperature show that apparent yield strength of the alloy experiences an abrupt decrease followed by a significant increase from 700 degrees C to 880 degrees C. Work hardening behavior is characterized by transition from the initial two-regime feature to the three-stage outlook. Concurrently, the maximum working hardening rate drops from 14000 MPa to 3000 MPa, which is concurrent with the shrinking volume fraction of primary a phase. Detailed discussion about the relationship between deformation mechanisms and p phase stability has been outlined.
