The peculiarity of contraction in the primary crystallization of amorphous Fe73.5Nb3Cu1Si13.5B9 alloy

Effect of Zr on the thermal stability and magnetic properties of Fe78Si9B13 glassy alloy

“…2a). Here, the exothermic peaks are denoted by T p1 , T p2 , T p3 and T p4 , it is found that the temperature interval between T p1 and T p2 increases with c Zr , suggesting that Zr can restricts the eutectic crystallization of the amorphous ribbon, which is similar to the effect of Cu and Ni in Fe 73.5 Nb 3 Cu 1 Si 13.5 B 9 glassy alloy [19]. In addition, a slight endothermic bump before the first exothermic peak can be seen in the DSC curves, which is also visible in the DSC curves with heating rates of 20, 30 and 40 K/min (not shown in this paper).…”

The peculiarities of the nanocrystallization process and copper addition effects for an amorphous Fe75.5Si13.5B9Cu2 alloy

“…Each curve drops drastically during the crystallization at around 770 K and displays a positive linear expansion tendency after complete crystallization. The value of contraction is around 0.0033-0.0038, a little lower than that of Finemet 0.0042 [22]. Referring to the contraction value of Fe-Si-B about 0.003-0.005 [23], there is no much difference as to the contraction of Fe-Si-Bbased metallic glasses during crystallization.…”

Microstructure and corrosion behavior of Al95−xNixY5 (x = 7,10) glassy ribbons

“…Generally, the rst exothermic peak at T x1 on the DSC curves of Al-TM-RE metallic glasses is associated with the formation of fcc-Al nanocrystals and the second/third one at T x2 /T x3 is associated with the formation of intermetallic compound phases in the manner of eutectic crystallization. 12 The T x1 of the ribbon with x ¼ 7 is much lower as compared to x ¼ 10, suggesting that its stability is lower than the residual amorphous matrix with x ¼ 10. In other words, the T x1 of the former scales the alloy's global stability and that of the latter indicates the alloy's partial stability.…”
