Ce is depleted from ferrite and pearlite surrounded by nodular graphite, and enriched in pearlite and ledeburite far apart from nodular graphite.
球墨周围的铁素体和珠光体是贫铈的，而远离球墨的珠光体和莱氏体是富铈的。

The iron phosphite eutectic and ledeburite in wearre-sistant cast iron are contradistinguished with metallography and microhardness and scanning electron microscope.
采用金相、显微硬度与扫描电镜，以区别含磷减磨铸铁中磷共晶与菜氏体。

After treatment, uniform and fine carbonization of no ledeburite organization were obtained. Therefore, we refined the organization of stainless steel and improved its property.
