Fe-based bulk metallic glasses (BMGs) were fabricated in Fe-Al-P-C-B alloy system by copper mold casting. Among them, Fe77Al3P9C9B2 (at.%) alloy shows the best glass-forming ability yielding the formation of an amorphous cylinder rod with a diameter of 3.0 mm. This alloy exhibits a high compressive strength of more than 3000 MPa and an appreciable plastic strain of up to 5.0%. In addition, the present alloy also shows good soft magnetic properties, i.e., high saturation magnetization of about 1.36 T and low coercive force of about 2.1 A/m. The integration of high GFA, good mechanical and soft magnetic properties along with low materials cost for the Fe-Al-P-C-B BMG makes it a competitive candidate as structural and functional materials.
