Ti－15－3钛合金的成分控制及性能研究

Chemical Composition Control and Properties Study of the Ti-15-3 Titanium Alloy

研究了铝和氧对Ｔｉ－１５－３钛合金的力学性能和冷成形性能的影响，提出了该合金的成分控制范围，为该合金的工业化稳定生产提供了依据。针对我国的国情，提出了与３０ＣｒＭｎＳｉＡ结构钢等强度的时效制度，并研究了相应的力学性能。

The effects of aluminium and oxygen elements on the mechanical properties and cold formability of the Ti-15-3 titanium alloy have been studied,this artical also gives the range of chemical composition control which provides basis for stable indusity production of the alloy. To counter the condition of our country,an aging treatment which can provide the same strength level of 30CrMnSiA structural steel has been proposed,the corresponding mechanical properties have been studied.
