Abstract

Abstract: Effect of solution and aging treatment on quasi-static tensile properties and dynamic compressive properties of the Ti-6Al-4V ELI titanium alloy was studied by means of universal mechanical testing machine and Hopkinson pressure bar test. The results show that after solution and aging treatment (solution temperature of 941 ℃), the yield strength and tensile strength can reach more than 1097 MPa and 1167 MPa, respectively. Compared with Ti-6Al-4V ELI titanium alloy before heat treatment, the strength is significantly improved and the plasticity indexes are maintained at a higher level. Meanwhile, the dynamic compression properties of the Ti-6Al-4V ELI titanium alloy is significantly improved at different strain rates. The relationship between the dynamic compression strength and the lgε· is linear, and the dynamic compression strength increases with the increase of strain rate.

Key words: solution and aging treatment, Ti-6Al-4V ELI titanium alloy, tensile properties, dynamic compression properties
