摘　　要：以金属隔膜用TA1ELI纯钛板为研究对象,研究热处理温度对其力学性能的影响,通过改善原材料性能得到塑性更强、翻转性能更好的金属隔膜。结果表明,与原始态相比,经610、660、710℃3种温度的真空热处理后,TA1ELI板材的抗拉强度、规定非比例延伸强度和断面收缩率均有所下降,断后伸长率有所提升。采用710℃进行真空热处理时,断后伸长率均可达到60%以上。依据试验得出的不同热处理温度对材料力学性能的影响,可根据金属隔膜实际的设计特性,制定合理的热处理工艺参数。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 vacum 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.
