尽管钛是一种高度活性的金属，但由于它表面能形成很稳定和完整的自愈合的氧化膜，故在有应力腐蚀的环境中，比其它普通结构合金具有很好的抗开裂能力，如在沸腾的42％MgCI。或10％Na0H溶液中承受应力时，钦合金件不会开裂，而许多不锈钢件却几乎全部开裂．但在某些环境中钛合?
Although titanium is a highly reactive metal, its surface is capable of forming a very stable and complete self-healing oxide film and therefore has excellent cracking resistance over other common structural alloys in stress corrosion environments. As in the boiling 42% MgCI. Or 10% Na0H solution to withstand stress, the alloy pieces will not crack, and many stainless steel parts are almost all cracking. But in some environments titanium?
