STRUCTURAL FEATURE OF AS-CAST HIGH Cr INJECTION MICROALLOYING MARTENSITIC CAST IRON
微合金化铸态马氏体铸铁的组织特征

The microstructure of as-cast high Cr injection microalloying marte- nsitic cast iron and the substructure of martensite in it have been observed under SEM and TEM. The alloying element distribution related to phase formation, as well as the various types of branch and distortion of carbide in the martensitic cast iron have been explored by using X-ray diffraction and electron probe analy- sis.
