摘要
通过研究NM450耐磨钢板在不同回火温度处理条件下,硬度、磨损量随温度的变化规律,结果表明,NM450耐磨钢板硬度、耐磨性能随回火温度升高而降低。组织观察发现,随回火温度升高,相邻马氏体板条逐渐合并的现象明显。
The variation law of hardness and wear volume of NM450 wear resistant steel with temperature under different tempering temperatures was studied in the paper. And the result showed that,the hardness,wear resistance of NM450 wear-resistant steel plate were decreased with the increasing of tempering temperature. The microstructure observation found that,with the increasing of tempering temperature,the merging of adjacent martensite lath was gradually obvious.
