摘要
研究了含碳量约（20~30）×10-6的50W 800冷轧无取向硅钢板的织构与磁时效行为的关系。200℃×24 h的磁时效试验结果表明,α-Fe{100}面的平均弹性模量最低,且与渗碳体的弹性模量接近,因此渗碳体易沿{100}面片状析出,造成磁时效,使硅钢板的铁损升高。磁化时180°磁畴畴壁的驱动力与硅钢板织构有密切关系,其〈100〉平行于外磁场方向的织构有利于减小磁时效导致的铁损增幅,降低钢板的磁时效效应。
The influence of texture on magnetic aging behavior of 50W700 non-oriented silicon steel sheets con-tening about（20~30）×10-6C was investigated.The results of magnetic aging at 200 ℃×24 h show that average Young＇s modulus in {100} plane of α-Fe is the lowest and near to that of cementite.Consequently,the cementites are easy to precipitate along the {100} planes of ferrite matrix during the magnetic aging,thus producing magnetic aging effect and resulting in an increase in the coreloss of silicon steel sheets.The force driving 180° domain wall is under the considerable influence of the texture in silicon steel sheets during the magnetizing.The texture the 100 of which is parallel to external magnetic field will be beneficial to decrease in coreloss increment induced by the magnetic aging and to the reduction in magnetic aging effect of the silicon steel sheets.
