退火处理对含Zr高硼钢微观组织的影响

Effect of Annealing on the Microstructure of High Boron Steel Containing Zr

摘要: 对含Zr高硼钢进行了三种温度的退火处理, 用扫描电镜对铸态和退火态组织进行了观察和分析。结果表明: 退火可以使含Zr高硼钢基体中的Fe-B化合物少量溶解, 使硼化物网状的连续性有轻微破坏; 但Zr-B相相当稳定, 几乎不受退火的影响。

Abstract: A steel with high content of boron was annealed at three temperatures, and the microstructures of the steel at cast and at annealing were analyzed with SEM.The results show that annealing can make a small amount of Fe-B compound dissolved, and the annealing has no effect on Fe-B compound.
