摘要

Fe-24Cr-12Co-1.5Si ribbons were prepared by simple melt spinning and aging processes, and their microstructure and phase transition were studied. The average grain size of the aged ribbons is similar to 4.22 mm, much smaller than that of traditional bulk Fe-Cr-Co alloy. The as-spun ribbons are mainly composed of BCC-type alpha and FCC-type Cr(M). During aging treatment, the Cr(M) phase firstly partly transforms into (CrSi)(0.99)(FeCo)(1.01) at the initially higher aging temperature, accompanied by the continuous spinodal decomposition of alpha ->alpha(1+alpha 2) and at the lower aging temperature the residual Cr(M) and a turn into Fe(Si, M)(2) (M = Cr, Co) and Co2Si rather than (CrSi)(0.99)(FeCo)(1.01). And a new uniform cellular microstructure is formed in the ribbons after multi-stage aging, in which the (Fe, Co)-rich alpha phase is located in the cellular interior, while the Cr-rich alpha 2 phase concentrates in the cellular boundaries.
