Abstract

The effect of Y addition on the glass forming ability (GFA) of in Fe ₇₀TM(TM=Mn, Mo, Ni)₁₃B₁₇ alloys have been examined in the present study. Substitution of 3-10 at% Fe with Y improves the GFA. Fe_70-xMn₁₃B₁₇Y_x, (x = 5) and Fe_70-xMo₁₃B₁₇Y_x (x = 3) alloys exhibit high T_rg (= T_g/T_l) (>0.55) and γ (= T_x/[T_l + T_g]) (>0.37) values enabling fabrication of 1 mm diameter bulk metallic glass. The GFA improves when addition of Y decreases the melting temperature, and, at the same time, increases the crystallization onset temperature. Extended Kissinger analysis of the DSC data indicates that a kinetic boundary condition for the formation of the amorphous phase widens by addition of Y.
