Abstract

Abstract: Effect of heat treatment temperature on mechanical properties of TA1ELI pure titanium plate for metal diaphragm was studied in order to improve the properties of raw materials, plasticity and inversion performance of metal diaphragms. The results show that compared with the original state, after vacuum heat treatment at 610, 660 and 710 ℃, the tensile strength, proof strength at 0.2% non-proportional extension and percentage reduction of area decrease, but the elongation increases with the increase of heat treatment temperature. When vacuum heat treatment is performed at 710 ℃, the elongation can reach more than 60%. Through the study of heat treatment process, the influence of different heat treatment temperature on mechanical properties of the material is obtained. Reasonable heat treatment process parameters can be formulated according to the actual design characteristics of the metal diaphragms.

Key words: heat treatment, commercial pure titanium TA1ELI, metal diaphragms, mechanical properties
