摘要
研究了Q2 35钢在非稳态脉冲电流作用下正火后组织的变化。结果表明 ,脉冲电流可以使Q2 35钢的正火组织均匀化。随着脉冲电压和脉冲频率的增加 ,其组织均匀化程度也增加。初步讨论了在固态相变中 。
This paper deals with the structural change of Q235 steel nonder nonsteady pulse electric current during normalizing.The result indicated that the pulse electric current can homogenize structure of Q235 steel,as the increase of pulse voltage and pulse frequency,the homogenization effect is enhanced.The mechanism that pulse electric current homogenize the structure of solid transformation was discussed.
