【Abstract】 The effects of alloying elements on the work hardening ability of as cast manganese steels wre carried out by means of compressive tests. The experiment shows that the decrease of Mn in the steel results in lowering austenite stability, which may increase it’s work hardening ability. The additions of N, Cr into the melt and a suitable N/Cr ratio resulted a significant enhancement of the work hardening ability. The mechanism of work hardening ability of as cast manganese steel was mainly analysed.更多还原
