Abstract

The microstructure and mechanical properties of cast titanium alloy TA31 under different conditions at room temperature were investigated.And the mechanical properties of specimens after annealing treatment under room temperature were analyzed.Through experiment and actual application

the results show that TA31 alloy casting presents stable properties

where the tensile strength

yield strength

elongation and fracture contraction rate are more than 877 MPa

754 MPa

10.5% and 14%

respectively

meeting the specification and the operating requirement.
