Abstract

The glass-forming ability of Fe-based metallic glass Fe_71.2-xC_7.0Si_3.3B_5.5P_8.7Cr_2.3Al_2.0Mo_x (x = 0-6.5 at.%), which can be produced in large quantities and cost-effectively using hot metal and commercial raw materials, was significantly enhanced by optimizing the Mo content, leading to the formation of a fully amorphous rod of 6 mm in diameter with high compressive fracture strength (∼3.3 GPa). It is concluded that the enhanced glass-forming ability is attributed to the suppression of the primary α-(Fe, Mo) phase by the optimum amount of Mo substitution for Fe.
