摘要： <正> The microstructure and martensite substructure of as-cast martensitic high-Cr cast iron byinjection microalloying have been studied by usig SEM and TEM.The relationship betweendistribution of alloying elements and phase formation of carbide,as well as various branchingand distortion of carbide,have been analysed by X-ray diffractometer and EPMA.
