Formation of bulk magnetic ternary Fe80P13C7 glassy alloy

Bulk magnetic Fe80P13C7 glassy alloy rods with a maximum diameter of ∼2.0 mm have been prepared by means of the fluxing technique and so-called J-quenching technique and it is the first ternary Fe-metalloid-based bulk magnetic glassy alloy reported. The magnetic measured results for the as-prepared specimens indicate a very high saturation magnetization Js of 1.53 T at room temperature. The compressive test shows that the as-prepared rod specimens have a high compressive strength of 3.23 GPa and a considerable large plastic strain of 1.1%.

► Fe80P13C7 BMG rods with a Dmax of 2 mm were prepared by fluxing and J-quenching techniques.
► It is the first ternary Fe-metalloid-based magnetic BMG.
► The as-prepared Fe80P13C7 BMG specimens exhibit a Js of 1.52 T and εp of 1.1%.
► It indicates that J-quenching technique is an effective technique to prepare BMGs.
