Abstract: The microstructure and martensite substructure of as-cast martensitic high-Cr cast iron by injection microalloying have been studied by usig SEM and TEM.The relationship between distribution of alloying elements and phase formation of carbide,as well as various branching and distortion of carbide,have been analysed by X-ray diffractometer and EPMA.

Key words: high-Cr cast iron, microalloying, martensite, substructure, carbide
