研究了稀土复合变质对新型铸造热锻模具钢(CHD钢)组织与性能的影响。
The effects of rare earth (re) complex modification on structure and the properties of a new cast hot-work die (CHD) steel were investigated.
研究了新型精铸热锻模具钢的高温磨损性能，并与H13钢进行对比探讨高温磨损机理。
The high temperature wear property of a new type precision cast hot-forging die steel was studied, and compared with that of H13 steel. The mechanism of the high temperature wear was discussed.
结果表明：h13热锻模具钢经此工艺处理后，具有较高的硬度和热疲劳性能，延长了模具的使用寿命。
The results show that the H13 steel treated by new process has higher hardness and heat-fatigue property. The service life of hot-forge die is prolonged.
