摘要
The glass-forming ability of Fe-based metallic glass Fe71.2-xC7.0Si3.3B5.5P8.7Cr2.3Al2.0Mox (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 (similar to 3.3 GPa). It is concluded that the enhanced glass-forming ability is attributed to the suppression of the primary alpha-(Fe, Mo) phase by the optimum amount of Mo substitution for Fe.
