| Abstract: | The influences of structures obtained through various heat treatment pro cesses on the hardness and impact toughness of AOCrMnMo steel are studied in this paper.The results show that if the steel is in quenched and tempered conditon,it possesses higher impact toughness and lower hardness, and if the steel is in isothermally quenched condition,it possesses higher hardness and medium impact toughness. For the parts which work under small energy impact, the low bainite structure is the best. |
