Theirmorphologies and compositions were also analyzed. A new type of microstructure called pearlite-like was found. The differentiation of characteristics into various zones across the weld joint isfeatured by TEM photos in contrast to the conventional metallographs. Key words： weld joint structure    TEM observation    pearlite-like 收稿日期: 1988-06-18      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 潘春旭 施雨湘 王仁卉 桂嘉年 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1988/V24/I6/450 1 井川博,新成夫,乾正弘.熔接学会志,1974;43:162 井川博,新成夫,中野昭彦,熔接学会志,1974;43:247 2 施雨湘,张有为.焊接学报.1985;6(4) :177 3 周振丰,金属熔焊原理及工艺,(下册),机械工业出版社,1981:94: No related articles found!
