研究了Ф180 mm的大规格M2高速钢在不同热处理工艺条件下的组织和性能,分析了不同淬火温度下碳化物的溶解以及长大趋势,奥氏体晶粒的长大情况。通过实验制定出Ф180 mm规格高速钢的热处理工艺。
The microstructure and properties of Ф180 mm large size M2 highspeed steel under different heat treatment conditions were studied. The dissolution and growth of carbides and the growth of austenite grains at different quenching temperatures were analyzed. Through experiments to develop Ф180 mm high-speed steel specifications of the heat treatment process.
