摘　　要：为实现TC4和TC11两种钛合金的有效连接,提升TC4/TC11钛合金的拉伸性能和塑性,分别对TC4和TC11两种钛合金粉末实施固溶处理后,采用单纯激光和点式锻压激光两种成型工艺对两种材料进行焊接。为验证TC4/TC11钛合金的综合性能,研究对钛合金材料的表面形貌进行观测并测试其拉伸性能。根据结果可知,相较于单纯激光工艺,点式锻压激光成型工艺下制备的TC4/TC11钛合金具有更强的拉伸性能、抗拉强度和屈服强度分别增加了105.2%和116.4%。相较于未经固溶处理的TC4/TC11钛合金情况,经过固溶处理的合金材料具有更高的塑性,有助于提升钛合金材料的可加工性。经研究发现,固溶处理和点式锻压激光成型工艺能够有效提升TC4/TC11钛合金的拉伸性能和可加工性能。In order to realize the effective connection of TC4 and TC11 titanium alloys,the tensile properties and plasticity of TC4/TC11 titanium alloys were improved.In this study,TC4 and TC11 titanium alloy powders were solution treated,and the two materials were welded by two forming processes:simple laser and point forging laser.In order to verify the comprehensive properties of TC4/TC11 titanium alloy,the surface morphology of titanium alloy materials was observed and its tensile properties were tested.According to the results,compared with the simple laser process,the TC4/TC11 titanium alloy prepared by the point forging laser forming process has stronger tensile properties,and the tensile strength and yield strength are increased by 105.2%and 116.4%,respectively.In addition,compared with TC4/TC11 titanium alloys without solution treatment,the solution-treated alloy materials have higher plasticity,which helps to improve the machinability of titanium alloy materials.It is found that solution treatment and point forging laser forming process can effectively improve the tensile and machinability of TC4/TC11 titanium alloy.
