本文研究了碳、锰、铬、钛含量及不同的热处理工艺对奥氏体锰钢原始硬度与非强烈冲击工况下的加工硬化性能的影响。试验结果表明:随碳、铬、钛含量提高,锰含量降低,材料的原始硬度得到提高。还表明:随含碳量提高,锰、钛量降低,材料的加工硬化能力得到改善。综合结果表明,提高含碳量、降低含锰量,在水韧处理之后继之以时效处理有利于改善材料在非强烈冲击工况下的耐磨性。现场运行试验的结果证实了上述结论,推荐材料的耐磨性比普通高锰钢提高了60％。
In this paper, the effect of carbon, manganese, chromium, titanium content and different heat treatment processes on the work-hardening properties of austenitic manganese steel under initial hardness and non-severe impact conditions was studied. The experimental results show that with the increase of carbon, chromium and titanium contents, the manganese content decreases and the original hardness of the material increases. Also showed that: with the increase of carbon content, manganese, titanium decreased, the work hardening ability of the material is improved. The comprehensive results show that increasing the carbon content and reducing the content of manganese can improve the wear resistance of the material under non-intense impact conditions after hydration treatment followed by aging treatment. The results of the field operation test confirmed the above conclusion. The wear resistance of the recommended material is 60% higher than that of ordinary high manganese steel.
