Abstract

The effect of substitution of Y for Fe on the glass forming ability (GFA), magnetic and mechanical property has been studied in Fe_{77 - x}Nb ₆B₁₇Y_x (x = 0-4) alloys. Replacement of 1-4 at.% Fe by Y increased the thermal stability of the glass and liquid phase in the Fe-Nb-B-Y alloys. It was found that the Fe₇₄Nb₆B ₁₇Y₃ alloy exhibited the largest T_rg (0.60) and γ (= T_x/[T_g + T_L]) (0.396) values enabling the fabrication of bulk metallic glass (BMG) with a diameter of up to 2 mm. The BMG alloy (≥74 at.% Fe) exhibited high compressive fracture strength and hardness of about 3 GPa and 1060 Hv, respectively. The partial replacement of 3 at.% Fe by Y in Fe-Nb-Y-B improved the alloy magnetization saturation by about 10%.
