中频脉冲磁场对Q275钢组织及残余应力的影响研究

摘要

After IF pulsed magnetic field on Q275 steel for processing, the calibration points were observed wathed from metallographic, dislocation structures and surfaces morphology respectively. The potential mechanism of magnetic treatment on residual stress were analysized from microcosmic angle.%磁处理是一种通过动态磁场与铁磁性工件相互作用来改变工件残余应力的新方法。文中以经过中频脉冲磁场处理的Q275钢件为观察目标，对其标定点分别进行金相、位错结构及表面形貌的观察，探索磁处理对Q275钢中残余应力的影响及磁处理影响残余应力的潜在机理，为磁处理的实际应用奠定基础。
