【摘要】

：

选用热轧中锰耐磨钢为实验材料,Hardox马氏体耐磨钢为对比材料,在M2000多功能摩擦磨损试验机上研究了冲击和滚动滚复合摩擦磨损性能,利用XRD、SEM和TEM等分析了组织转变及磨损机理.实验结果表明,热轧中锰钢比Hardox马氏体耐磨钢表现出更好的抗冲滚磨料磨损性能.冲滚磨损表面存在厚度达1000μm的硬化层,最高显微硬度达490HV,洛氏硬度达53HRC,加工硬化十分显著.位错强化、形变孪晶

关于实现低碳绿色炼钢的若干设想

钢铁工业是能源密集型的行业，消耗大量化石能源，排放大量CO2.中国作为世界第一钢铁产量的大国，钢铁工业CO2 排放约占全国总排放的15％，同时炼钢过程中排放大量的污水.在世界性 CO2 减排和环境保护的压力下，欧盟、日本、韩国等主要钢铁生产地区均制定了相应的规划和技术措施，中国的钢铁行业CO2 排放量现在仍维持在相对较高的水平，随着环境要求的日趋严格，有效减少钢铁生产 CO2 和污水排放已成为中国

Cr对高硅钢组织及性能的影响研究

高硅钢具有优异的软磁性能,但其室温脆性严重.本文主要研究了添加不同含量的Cr对高硅钢组织、有序相及性能影响.通过常规的热轧与温轧工艺制备了厚度约为0.3mm的不同Cr含量的高硅钢薄板,且温轧温度低于600℃.利用金相显微镜和透射电镜分别观察了高硅钢的微观组织和有序相,并测量了高硅钢的显微硬度和磁性能.试验结果表明:适量Cr的添加能改善高硅钢的可轧性,制备出较宽且板型较好的薄板.Cr的添加能有效细化
