摘要:Co-addition of appropriate Mo, Cr and Ni in the Fe80P12C4B4 alloy not only enhances the thermal stability of the supercooled liquid and glass-forming ability (GFA) but also reduces the glass transition temperature (T-g) of the Fe-based metallic glass. The Fe55Ni15Cr7Mo3P12C4B4 bulk metallic glass (BMG) exhibits a low T-g of 690 K, large supercooled liquid region (Delta T-x) of 60 K, and high GFA with a critical diameter of 2.5 mm. The co-addition of Mo, Cr and Ni remarkably improves the corrosion resistance of the BMGs in 1 M HCl and 0.5 M H2SO4 solutions, which is superior compared to the SUS316L stainless steel. The alloys also possess high compressive yield strength of similar to 3.01 GPa with distinct plastic strain of similar to.2%. The good combination of low T-g, large Delta T-x, high GFA, excellent corrosion resistance and mechanical properties makes the developed (Fe, Ni, Cr, Mo)(80)P12C4B4 BMGs show great promise as anti-corrosion materials suitable for thermoplastic processing.
