Influence of Heat Treatment on Microstructure and Tensile Property of Ti-5Al-5Mo-5V-3Cr-1Fe Alloy

Abstract:

The effect of solution and aging temperatures on microstructure and tensile property of Ti-5Al-5Mo-5V-3Cr-1Fe Alloy was investigated. The results showed that the tensile strength lowered, when the solution and aging temperature rose respectively. The alloy with different heat treatments showed better tensile strength totally, i.e. the minimum level of ultimate and yield strength passed 1280 MPa and 1245MPa. The highest ultimate tensile strength could reach 1445 MPa. After (α+β) solution and aging treatment, the microstructure consists of primary α phase and transformed β phase with fine secondary α phase precipitating to improve the tensile strength effectively.
