【摘要】 通过对在切削加工中产生裂纹的1J22软磁合金零件进行宏观分析、化学成分分析、金相检验和扫描电镜分析等,得出该零件切削加工裂纹产生的原因为该合金有序化α相的解理开裂敏感性和较强的冷作硬化能力。解决的措施为:通过锻后热处理的手段抑制有序相的产生以及改进切削工艺以降低冷作硬化的效果。更多还原

【Abstract】 Based on macro analysis, chemical analysis, metallographic examination and scanning electron microscopy analysis of the cracks in machining of 1J22 soft magnetic alloy, we can conclude that machining crack appears because of the alloy’s, the ordered phase α cleavage cracking sensitivity and strong work hardening ability. Solution measures: it can in habit the production of ordered phase by means of heat treatment after plating and reduce the effect of cold-work hardening via improving the cutting process.更多还原
