논문 초록 (Abstract)
The effect of Y addition on the glass forming ability (GFA) of in Fe70TM(TM=Mn, Mo, Ni)13B17 alloys have been examined in the present study. Substitution of 3-10 at% Fe with Y improves the GFA. Fe70−xMn13B17Yx (x = 5) and Fe70−xMo13B17Yx (x = 3) alloys exhibit high Trg (=Tg/T1)(>0.55) and γ (=Tx/[T1 + Tg]) (>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.
