金属的内部组织结构和组织状态是决定金属材料性能的重要因素 ,着重从钢材化学成分波动 ,S、P杂质含量 ,成分偏析 ,以及不同熔炼方式和脱氧方法 4个方面论述了钢铁冶金质量对热处理性能的影响
The internal structure and microstructure of the metal are the important factors that determine the performance of the metal material. The emphasis is placed on the influence of the quality of the steel metallurgy on the heat treatment, including the fluctuation of the chemical composition of the steel, the content of S and P impurities, the segregation of components, and the different melting methods and deoxidation methods The impact of performance
