摘要

The influence of various Fe contents on the microstructure and mechanical properties of Ti-30Zr-5Al-3V (ZTAV) alloy was investigated. After Fe addition, the grain refinement is obvious and the phase composition changes as a'+β→(3. Ti-30Zr-5Al-3V-0.5Fe exhibits a better mechanical property (σ_b≈1420MPa, ε_f≈5.34%) than Ti-30Zr-5Al-3V (σ_b≈1302 MPa, ε_f≈4.28%). Highest ultimate tensile strength (σ_b≈1667MPa, ε_f≈2.34%) have been achieved in Ti-30Zr-5Al-3V-1.5Fe. The mechanical properties change owe to the phase transformation, grain refinement, and solid solution strengthening caused by Fe addition.
