采用氢化-脱氢(HDH)钛粉和氢化钛粉制备MIMTi-6Al-4V合金

Preparation of P/M Ti-6Al-4V Alloy Using Hydrogenation-Dehydrogenation (HDH) Powder and Hydride Powder

以HDH钛粉制备MIMTi-6Al-4V合金的过程为参照,对使用氢化钛粉为原料制备P/M模压钛合金以及MIM钛合金的工艺过程进行了探索。使用HDH钛粉制备的MIMTi-6Al-4V合金抗拉强度为819MPa,拉伸样延伸率为7%;使用氢化钛粉制备的P/M模压Ti-6Al-4V合金拉伸样抗拉性能高于850MPa;使用氢化钛粉为原料制备MIMTi-6Al-4V合金,顺利实现了脱氢-脱脂过程。

Taking the process of producing MIM Ti-6Al-4V alloy by HDH powder as a reference, the processes of making P/M Ti-6Al-4V and MIM Ti-6Al-4V by using TiH2 have been discussed. When using HDH Ti powder making MIM Ti-6Al-4V the tensile strength is 819 MPa and elongation percentage is 7%. When using TiH2 powder making P/M Ti-6Al-4V the tensile strength is over 850 MPa. And when using TiH2 powder making MIM Ti-6Al-4V, processes of dehydrogenation and debinding are successfully reached.
