铸铁中磷共晶类型及分析方法

The Type and Examination Method of PhosphideEutectic in Cast Iron

用光学显微镜和电子显微镜分析表明,铸铁中磷共晶按组织组成物及形态可分为四种类型.用热浸蚀方法可显示磷共晶中组织组成物的形态和颜色特征.

Analysis was earned out on the microstructure and morphology of phosphide eutectic in cast iron which was divided into four types using light and electron microscope. The morphology and color characteristic of microstructure of the phosphide eutectic can be showed with cold and hot erosion method.
