【Abstract】 Since it is possible by spheroidizing the carbide to improve radically the brittleness,wear resistance and machinability of the anti-abrasive castings,an introduction was made to the research achievement and experience of Japan in the research on spheroidized carbide-containing cast irons and as the emphases,the chemical compositions,microstructures,principal properties of the spheroidized carbide-containing corrosion-resistant cast iron,white iron,high-manganese cast iron and low-expansion cast iron,as well as the spheroidizing process of the carbide were analyzed.更多还原
