Study on the effect of annealing heat treatment on the mechanical properties of selective laser melting of TA17 titanium alloy
Aiming at the problem of high strength and low plasticity in selective laser melting(SLM) test sample of TA17 titanium alloy,the annealing heat treatment process under with different temperatures and cooling modes was studied,By studying the test results of mechanical properties of the test sample before and after annealing heat treatment,the influence of annealing heat treatment process on the mechanical pro-perties of the SLM test sample of TA17 titanium alloy was analyzed. The results show that by annealing heat treatment of air cooling after vacuum heat preservation at 900~950℃ for 2 hours,the strength of the SLM test sample reduces,the plasticity and the toughness obviously improve,the overall mechanical properties are balanced and meet the technical requirements.
