摘要
综述了稀土元素和杂质对铝锂合金微观组织及力学性能的作用,概括了杂质致脆及稀土微合金化的规律与机制,根据已有研究结果,对目前铝锂合金的发展与应用中需要引起重视的问题,提出了某些观点与建议。
The study status for the effects of impurities and rare earth elements in Al Li alloys has been surveyed. Particular attention has been paid to the mechanical properties in respect of different conditions and the mechanisms responsible for impurity induced embrittlement and rare earth microalloying. According to the presented investigations, some suggestions and viewpoints have been proposed to solve the noteworthy problem in the development and application of Al Li alloys.
