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 (Is) of the alloys reduced with increasing Mo content, the coercive force (Hc) 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 Is of 0.81–1.11 T, low Hc of 2.07–4.87 A/m, high Vicker's hardness of 860–992, high compressive yield strength of over 3000 MPa with a distinct plastic strain.
