一种TZM和WRe异种合金的低温连接方法
摘要：
本发明提供了一种TZM和WRe异种合金的低温连接方法，是以Ti粉作为活性中间层，通过放电等离子烧结技术对TZM合金与WRe合金在低于母材的再结晶温度下进行扩散焊接，获得TZM合金与WRe合金的连接件。通过本发明的焊接方法可保证母材不发生再结晶的同时，得到强度高、成型好的TZM/WRe异种合金连接件，接头室温剪切强度可达263MPa。
摘要（英）：

The invention provides a low-temperature connecting method of a TZM and WRe dissimilar alloy. Ti powder is adopted as an activated middle layer, a TZM alloy and a WRe alloy are subjected to diffusion welding at the temperature lower than the recrystallization temperature of base metal through the spark plasma sintering technology, and a connecting part of the TZM alloy and the WRe alloy is obtained. By means of the welding method, it can be guaranteed that the base metal is not recrystallized, meanwhile, the TZM/WRe dissimilar alloy connecting part high in strength and good in forming is obtained, and the room temperature shear strength of a connector can reach 263 MPa.
