The chemical heter-ogeneity was clearly observed on the transition zone between the laser melted zone and heat-affected zone by means of EPMA, AES and SEM. This heterogeneity is rather serious duringhigh temperature tempering, so the decarburization on the transition zone side and the recarbu-rization on the melted zone side were found. Key words： laser alloying    heterogeneity    transition zone    microstructure 收稿日期: 1990-01-18      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 程永兴 李根富 余少罗 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1990/V26/I1/64 1 Boeittinger W J.
