| Abstract: | The feassibilty on application of Cu-Mo-Cr alloyed bainite ductile cast iron for millingball has been studied.using hot sake-out the casting remaining heating with the step austempering heat treatment,the matrix microstructure of impact sample treated by above-mentioned process consists of lower bainite with a small amount of martensite and risdual austenite, which has impact value of more than 14 J/cm2 and hardness number of more than 52HRC,the service life life was found to be superior to forge steel and as lood as hight-chromium cast iron millingball. |
