研究了直接由Ｔｉ，Ｎｉ元素粉末制取ＴｉＮｉ记忆合金管接头的过程，由Ｔｉ，Ｎｉ粉末直接得到了反应充分，结构密实的管接头坯料，经机加工制得的管接头扩径变形率＞６％，形状恢复率＞８０％。
The process of making TiNi memory alloy pipe fittings directly from Ti and Ni powder was studied. The pipe joints with sufficient reaction and compact structure were obtained directly from Ti and Ni powders. The diameter expansion deformation rate of pipe joints obtained by machining was> 6%, shape recovery rate> 80%.
