| Abstract: | In this paper, the author put forwards that the flaking off of the frog has something to do with low hardness and strength of high manganese steel. It also briefly discusses the basic theory on solution strengthening, precipitation strengthening,explosion and carburizing strengthening and methods of high manganese steel strengthening. It points out that these are the effective ways to improve the hardness and strength of high manganese steel and increase duration of high manganese steel frog. |
