1 引言为了通过连续退火处理生产过时效铝镇静钢板,必须通过析出 Fe_3C 使溶质碳含量降低至较低水平。正如 Kawasaki 等人报道的,大约在570K 温度时,采用过时效加工处理可使 Fe_3C 在 MnS 颗粒表面析出。这种过时
1 Introduction To produce over-aged aluminum-killed steel sheets by continuous annealing, the solute carbon content must be reduced to a lower level by precipitation of Fe 3 C. As reported by Kawasaki et al., Fe3C precipitates on the surface of MnS particles at about 570K with an over-aged treatment. This is outdated
