Among these systems, filler 6M, i. e.A1-Si(13.0)-Be(0.4—0.8)-Sr (0.03—0.06)-La (0.03—0.06) is regarded as the optimum. The erosion mechanism of molten filler metal on base metal has been also studied. In addition to the influences of brazing temperature and the composition of filler metal, the rate of solution of base metal into molten filler and the spreading out of molten filler along the fillet are other of importance in affecting the erosion of base metal during brazing. The fillets were annealed for different time intervals and only a little improvement of their strength and bending capacity was observed. 收稿日期: 1981-03-18      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 张启运 刘淑祺 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I3/300 [1] Schoer, H., Schultze, W., Ger.
