对于铸铁固态石墨化的研究,以往多采用淬火等不同手段将高温时的组织变化固定下来,在室温进行观察分析.本研究使用MEF高温全相显微镜直接观察记录白口铸铁试样在整个固态石墨化加热、冷却过程中的组织变化情况.
For the study of solid state graphitization of cast iron, in the past many different methods such as quenching were used to fix the change of microstructure at high temperature and observe and analyze at room temperature.In this study, direct observation and recording of white cast iron samples in whole solid graphite Heating and cooling during the organizational changes.
