传统使用的110Mn13铸钢,在低冲击磨损或纯磨损条件下不产生马氏体转变,其耐磨性不高。可以拟定两种方法改善高锰钢的耐磨性。一是调整钢中的段和锰含量。本文采用数理统计方法和电子计算机处理,研究了20炉不同碳、锰配合量的高锰钢。测定了耐磨损性和耐冲击-磨损性,并从110Mn13铸钢试样的重量损失为标准确定其相对耐磨性。二是通过合金化在钢中获得硬质点。采用强碳化物形成元素(钛、铌合金化时,由于固溶体中碳的贫化而
The 110Mn13 cast steel traditionally used does not produce martensite transformation under low impact or pure wear conditions and its wear resistance is not high. Two methods can be developed to improve the wear resistance of high manganese steel. First, adjust the steel section and manganese content. In this paper, using mathematical statistics and computer processing, studied 20 different high manganese steel with different carbon and manganese content. The abrasion resistance and impact-abrasion resistance were measured and the relative wear resistance was determined from the weight loss of 110 Mn13 cast steel specimens. The second is through alloying in steel to obtain hard points. The use of strong carbide forming elements (titanium, niobium alloying, due to the depletion of carbon in solid solution and
