摘要
应用光学显微镜、扫描电镜和透射电镜分析了激光熔融处理后的球墨铸铁熔化区、半熔化区组织。其中,着重于应用扫描俄歇探针SAM对石墨球和石墨球周围存在双壳层组织进行了显微化学分析。分析了球墨铸铁中球墨周围形成A壳层的机制。
Abstract
Accompanying the microstructure anatysis of Taser remelted nodular cast iron by means of OM, SEM and TEM, the paper mainlly dea's with the micro-chemical examination with Scanning Auger Microprpbe (SAM) for the graphite G and the double-shell structure arrourid'G, ?Fina^y tt is pointed out to explain the mechanism of forming equiaxial austenite shell !ayer surrounding the in nodular cas iron.
