几年来,由于技术革新时代的要求,人们对超耐热合金和钛合金的恒温(800～900℃)锻造极为关注。在锻造中金属模与被加工材料一起同时被加热,所以需要高温强度高的金属模材料。目前这种金属模具材
In recent years, due to the requirements of the era of technological innovation, people are extremely concerned about the constant temperature (800 ~ 900 ℃) forging of superalloy and titanium alloy. Since the mold is heated simultaneously with the material to be processed during forging, a mold material having a high temperature strength is required. The current metal mold material
