摘要
采用正火+淬火+回火工艺对耐磨锻球进行热处理,研究了不同正火结束温度对耐磨锻球组织及性能的影响.试验结果表明,耐磨锻球的正火空冷结束温度为 200℃时,组织为细小的回火马氏体和均匀分布的残余奥氏体,其表面、1/4R处和心部硬度分别为 58.6、58.4、58.4 HRC,冲击功为134 J,力学性能最优.
Abstract
The influence of different normalizing end temperature on the microstructure and properties of wear-resistant forged ball was studied by normalizing+quenching+tempering process.The test results show that when the normalizing air-cooling end temperature is 200℃,the microstructure is fine tempered martensite and uniformly distributed residual austenite,the surface hardness,1/4R and core hardness are 58.6,58.4 and 58.4 HRC,respectively,the impact energy is 134 J,and the mechanical properties are the best.
