研究了变形前脱溶处理对A1—2%Fe(质量分数)合金加工软化现象的影响,用电子探针能谱分析对A1-2%Fe合金的基体纯度进行了研究.结果表明:在673～773K进行脱溶处理时,固溶于基体中的Fe原子析出较快,具有显著的净化基体的作用,从而促进了加工软化.而在573K,873K脱溶处理时,由于固溶于基体中的Fe原子析出较慢,使基体净化不彻底,无明显的加工软化现象. The effect of pre-deformation treatment on the softening of A1-2% Fe alloy was studied, and the substrate purity of A1-2% Fe alloy was studied by energy dispersive X-ray photoelectron spectroscopy. The results showed that in 673 ~ 773K, the Fe atoms dissolved in the matrix precipitated faster and had a significant effect of purifying the matrix, thereby promoting the softening of the processing, while at 573K and 873K, due to the solid solution in the matrix Fe atoms precipitated slowly, so that the substrate is not completely purified, no obvious process softening phenomenon.
