(一) 绪言 高锰铸钢在使用过程中奥氏体组织产生加工硬化,韧性也很高,被广泛用作耐冲击磨损材料。而在不能使材料产生加工硬化的磨料磨损中,白口铸铁系材料性能比高锰铸钢的耐磨性好,但这两种材料的机械性能差异很大。为了应付磨损条件多 (A) Introduction High manganese steel in the process of using austenite resulting in work hardening, toughness is also very high, is widely used as impact wear materials. In abrasive wear that does not result in work-hardened materials, white cast iron systems have better wear resistance than high-manganese cast steel, but the mechanical properties of these two materials vary widely. In order to cope with more wear and tear conditions
