摘　　要：工业纯钛由于弹性模量低,易硬化,缩口性能低。本文通过四种钛管缩口试验,研究了缩口、旋锻成型异型管的工艺方法。分析了缩口方式、工艺设计等对加工件质量的影响,进行了缩口失稳原因查找。试验结果表明,选择合理的加工方式及工艺可制得满意的异型管。Due to the low elastic modulus and easy hardening of commercial pure titanium,necking performance is poor. The technology of nicking and rotating extrusion on special-shaped tube are studied by four kinds of titanium tube necking tests.The effect of necking method and technique on pipes was analyzed,and the reason of necking instability is explored. The result shows satisfying special-shaped pipes can be manufactured by selecting reasonable processing method and technology.
