钛基合金完美地集高的强度／重量比和优良的耐腐蚀性能于一身,它使这些合金挤身于各种各样的宇航、舰船、工业及商业应用最重要的先进材料之列。虽然钛被认为具有相当好的耐化学腐蚀能力,但是当钛基合金与含氢环境接触时会出现严重的问题,因为合金会吸收大量的氢,尤其在高温下。而氢与钛基合金相互作用的严重性及程度则直接与钛合金的显微组织及成分有关。本文论述了钛基合金的氢脆,研究了氢一钛之间的相互作用,包括氢在钛的α和β相中的溶解度及氢化物形成。另外,文章还归纳了氢在各种不同的钛合金中的有害影响。
Titanium-based alloys perfectly combine the strength / weight ratio with excellent corrosion resistance, making these alloys among the most advanced and advanced materials in a wide variety of aerospace, marine, industrial and commercial applications. Although titanium is considered to have quite good chemical resistance, it poses a serious problem when it comes into contact with a hydrogen-containing environment because the alloy absorbs a large amount of hydrogen, especially at high temperatures. However, the severity and degree of interaction between hydrogen and titanium-based alloys are directly related to the microstructure and composition of titanium alloys. In this paper, the hydrogen embrittlement of titanium-based alloys is discussed. The interaction between hydrogen and titanium is studied, including the solubility of hydrogen in α and β phases and the formation of hydride. In addition, the article also summarizes the harmful effects of hydrogen in various titanium alloys.
