铝锂合金在俄罗斯的飞机工业中成功地获得了应用，但在应用中常常对合金的淬透性重视不够，因此大尺寸构件出现未淬透现象，从而降低了合金的静态及周期抗裂纹扩展能力。本文介绍了俄罗斯学者关于合金化元素对固溶体稳定性及淬透性影响的研究结果 Al-Li alloys have been successfully used in the Russian aircraft industry, but the applications often underestimate the hardenability of the alloy, resulting in an unhardened appearance of large-sized components, thereby reducing the static and periodic crack growth resistance of the alloy ability. This article presents the findings of Russian scholars on the effect of alloying elements on the stability and hardenability of solid solutions
