摘要：The effects of Mo content on the thermal stability, glass-forming ability (GFA), magnetic and mechanical properties of Fe75-xMoxP10C10B5 (x = 0-10) metallic glasses were investigated. The stabilization of supercooled liquid and GFA were significantly enhanced by addition of Mo. Although the saturation magnetization (I-s) of the alloys reduced with increasing Mo content, the coercive force (H-c) decreased. The metallic glasses with x = 2.5-7.5 exhibit low glass transition temperature of 733-749 K, large supercooled liquid region of 61-96 K, and high GFA with critical fully glassy sample diameters of 1.5-3.0 mm. They also possess rather high I-s of 0.81-1.11 T, low H-c of 2.07-4.87A/m, high Vicker's hardness of 860-992, high compressive yield strength of over 3000 MPa with a distinct plastic strain.
