摘要: Abstract We have analyzed a set of minor hysteresis loops Fe alloys with 0.3 wt.% Cu in the isothermal aging at 773 K to elucidate influence copper precipitation on magnetic property. found that coefficients take maximum same time ∼100 min as Vickers hardness. This result indicates are sensitive structural transition precipitates from coherent noncoherent structure. The present analysis shows very useful for nondestructive evaluation degradation due view amount information and small field be required.
