Effect of Solution Treatment on Microstructure and Mechanical Properties of ZA35-0.1Ti Alloy

Microstructure of ZA35-01Ti alloy was investigated by XRD and metallurgical microscope.The mechanical properties of the alloy were determined,the fracture morphology of the alloy was observed,and the effects of solution treatment on the microstructure and mechanical properties of the alloy were studied.The results show that,at 385℃,with the increase of solution time,the mechanical properties of the alloy first increase and then decrease;when the solution time is 5 h,the best mechanical properties of the alloy occurs,the tensile strength,elongation and hardness reaches 396.0MPa,3.71% and 140HBS,respectively.After 385℃× 5 h solution treatment,the effect of solid solution strengthening is notable due to the full solution of the alloying element of Ti in alloy.
