退火处理对10钢显微组织及磁性能的影响

Effect of Annealing Treatment on Microstructure and Magnetic Performance of 10 Steel

分别对国产以及日产10钢显微组织进行分析,研究组织对10钢磁学性能的影响,并在此基础上通过对国产10钢进行退火处理以改善其磁学性能。实验结果表明:日产10钢显微组织更为均匀并且碳化物细小弥散,晶体化程度高,有着比国产10钢更为优异的磁学性能;对国产10钢进行退火处理可以有效改善组织的不均匀性,优化碳化物在组织中的分布,从而改善10钢的磁性能;冷却速度越慢,材料的剩余磁化强度越低,磁性能越好。

The microstructure of domestic and Japanese 10 steel and its influence on magnetic properties of 10 steel were studied. Annealing treatment was applied to domestic 10 steel to improve its magnetic properties. The experimental results show that microstructure of Japanese 10 steel is uniform and the carbide is fine, dispersed. Rs magnetic properties are more excellent than that of the domestic 10 steel. Annealing treatment can effectively improve structural homogeneity of domestic 10 steel and optimize distribution of carbide. Therefore, magnetic properties of 10 steel is improved. The slower the cooling rate, the lower the residual magnetization and the better the magnetic properties.
