The effects of minor alloying addition of Cu on the glass-forming ability and crystallization process of Fe71.7?xB16.7Si8.3Zr3.3Cuxand Fe72.5?xB16.7Si8.3Hf2.5Cux (x = 0, 0.3, 0.7, 1.0 and 1.3; at%) alloys were investigated. It was found that the critical glassformation size of rod samples gradually decreased from 2.5 to 1 mm with increasing Cu content in these alloys. Single α-Fe phase nanocrystalline alloys were obtained after isothermal annealing the Fe?B?Si?Zr/Hf?Cu glassy alloys containing0.7?1.0 at% Cu. The Fe71B16.7Si8.3Zr3.3Cu0.7alloy exhibited good soft magnetic properties with a high saturation magnetization(~ 1.22 T) and a low coercive force (~ 0.6 A/m) after annealing at 853 K for 10 min due to the precipitation of α-Fenanoparticles of 8 nm size in the glassy matrix. The structural evolution on annealing and the variation tendencies against Cucontent of the glass transition temperature, thermal stability and glass-forming ability of the Fe?B?Si?Zr/Hf?Cu amorphousalloys were discussed using a dual-cluster local structure model.
