The composition dependence of the crystallization temperature Tcr for Fe100-xZrx,(Fe1-xZrx)84B16 and Fe90-xMxZr10(M = V,Cr,Mn,Co,Ni,Si,B) amorphous alloys is investigated systematically. The main results are: the substitution of Zrfor some Fe in Fe-based amorphous alloysTcr exhibits an increase markedly; for amorphous Fe90-xMxZr10 alloys, Tcr increases following the order M = Mn, Cr, V and with increasing M content x, and decreases following the order M = Co, Ni and with increasing x; in most of the samples studied, the ratio of crystallization temperature to melting point is about 2/3; when the alloy composition was varied ( <20at%-M) or an alloying transition element was added, Tcr increased linearly with decreasing average number outer electrons per atom which was calculaied by taking into account both the s,p and d electrons of the transition metal atoms. These results are discussed in connection with various factors such as composition, phase diagram, melting point, interatomic force and e/a effecting the stability of amorphous alloys.
