Effect of ternary additions of silicon and aluminum on the ordering reaction in iron-cobalt

Solidification behavior, glass forming ability and thermal characteristics of soft magnetic Fe–Co–B–Si–Nb–Cu bulk amorphous alloys

“…Near equilibrium, the equiatomic FeCo is known to go through the ODT around 1000 K [19]. For the Cu-free base alloy, a higher T odt of 1128 K is observed which may be due to dissolved Si [20]. When Cu is present, the heat effects of ODT reactions become more pronounced and T odt values fall down to a range comparable to the equilibrium value of 1000 K. This is supported by a previous report [20] mentioning that Cu lowers T odt in B2-FeCo alloys.…”

Near equiatomic FeCo alloys: Constitution, mechanical and magnetic properties

“…Griest et al [53] reported the effect of small Si and Al additions in FeCo alloys. In thermal analysis studies, silicon was found to raise the ordering temperature but also reduce the amplitude of the corresponding peak (for example, T k = 805°C for 2 wt% Si).…”

7: Critical evaluation of constitution of aluminium-cobalt-iron system

“…GrIest et al 22 have examined the effect of additions of up to 2"loAlto alloys containing equal weight percentages of Fe and Co (Le. to CoFe (a 1 ) alloys), using inverse-rate thermal analysis.…”
