摘要
合理设计了中锰奥氏体基耐磨钢的成分,并选择合适的水韧处理工艺来获得一种介稳的单相奥氏体组织,在此组织基础上进行不同的等温热处理工艺,获得一定量的马氏体,以提高基体的初始硬度,又不恶化其冲击韧性,再通过与高锰钢(Mn13)在同等工况条件下进行耐磨性模拟对比实验,来选择适合中锰钢在中、低冲击磨料磨损条件下使用的热处理工艺和组织.同时对试样进行了金相组织观察及力学性能测试.
The composition of medium-Mn wear resistant steel and its water toughening processes were se-lected to get metastable single austenite structure. Certain content of martensite were formed by additional isother-mal heat treatment so as to improve the initial hardness of the steel while not deteriorating its impact toughness. Abrasive wear resistance of the steel under medium and low impact conditions were optimized through proper heat treatment by means of wear resistance evaluation, microstructure examination and mechanical testing.
