The weld metal is not brittle at Na content less than 20μg g-1. When Na content was increased to 50 μ g' g-1, the str Key words： Al-Mg-Li alloy    Na content    weld metal embrittlement 收稿日期: 1996-08-25      基金资助:国家自然科学基金 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 王兆清 应慧筠 于尔靖 陈萍 郭燕杰 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y1996/V10/I4/373 1Payne,Eynon．BritishPatent,787665,19572VaynblatYM,KopeliovichBA,GolderYGFizMetal1976,42:10213VaynblatYM,KopeliovichBA,GolderYGPhysicsofMetalsandMetallography,1976,42:1054WebsterDMetallurgicalTransactions,1987,18A:21815MondolfoLF著．王祝堂等译．铝合金的组织与性能．北京:冶金工业出版社,1988:285 No related articles found!
