高锰钢是一个有一百年历史的耐磨金属材料。广泛用于冶金矿山、工程机械、电力机械、建材工业、铁道等部门。消耗量很大。但在中等冲击、中等和较软物料的工况条件下的耐磨性显得不足。如何提高这种条件下的耐磨性、减少消牦量,是一个急需解决的带普遍性的问题。从1976年起到1980年,经过四年的研究工作,取得了如下的成果: 一、确定了沉淀强化高锰钢的最佳成分 为保证在奥氏体基体中析出弥散分布的二次相—碳化物,选择了较高的含碳量
High manganese steel is a 100-year-old wear-resistant metal materials. Widely used in metallurgical mines, construction machinery, electrical machinery, building materials industry, railway and other departments. Consumption is great. However, the wear resistance of medium-impact, medium and softer materials is not sufficient. How to improve the wear resistance under such conditions and reduce the amount of yam is an urgent problem to be solved. From 1976 to 1980, after four years of research work, the following achievements have been made: First, the best composition of precipitated high manganese steel was determined to ensure the secondary phase of precipitation and dispersion in the austenite matrix - Carbide, chose a higher carbon content
