摘　　要：采用金相观察、SEM-EBSD测试分析了加入稀土Ce后50W400无取向硅钢常化后组织与织构的演变规律,明确稀土Ce对常化后试验钢晶粒度和织构强度的变化趋势。结果表明,加入Ce可推迟常化时组织的完全再结晶时间,即添加稀土后的试验钢,在均温970℃下,保持晶粒尺寸均匀分布状态的时间,由155 s可以推迟至215 s,且晶粒尺寸相比更小。同时,在试验钢的纵截面厚度方向,有利面织构{100}和{110}占比增加,不利面织构{111}占比减少。Evolution of the normalizing microstructure and texture of 50W400 non-oriented silicon steel after adding rare earth element Ce was analyzed by means of metallographic observation and SEM-EBSD instruments.This investigation aimed to clarify the trend of changes in grain size and texture strength of the tested steel after normalizing.The results indicate that the addition of Ce can delay the complete recrystallization time during normalizing.Specifically,with rare earth Ce adding,the time for maintaining a uniform grain size distribution at a uniform temperature of 970℃can be postponed from 155 s to 215 s,and the grain size is smaller.Furthermore,in the thickness direction of the longitudinal section of the tested steel,the proportion of favorable surface textures{100}and{110}increases,while the proportion of the unfavorable surface texture{111}decreases.
