摘　　要：以ECAE热挤压处理GCr15钢为对象,研究退火工艺对其微观组织和性能的影响。结果表明,随退火温度的升高,GCr15钢微观组织中的碳化物形貌发生变化,由大块状最终变为细小颗粒状。随退火温度的升高和保温时间的延长,GCr15钢试样的硬度呈下降趋势。The effect of annealing temperaturesa and times on microstructure and properties of GCr15 steel after ECAE process was studied. The results show that the carbide image changed from big bulk to fine particles with increasing of annealing temperature. And the hardness of GCr15 samples decrease with increasing of annealing temperatures and holding times.
