| titleOfInvention | A kind of FeCoNiSnx medium entropy alloy and preparation method thereof |
| abstract | The invention discloses a FeCoNiSnx medium entropy alloy and a preparation method thereof. The content of the constituent elements Fe, Co, Ni and Sn is 1:1:1:x according to the atomic ratio, when x=0.2, 0.4, 0.6, 0.8 When x=0.9 and 1, it is a hypoeutectic medium entropy system, when x=0.9 and 1, it is a eutectic medium entropy system, and when x=1.1, it is a hypereutectic medium entropy system; the primary phase of the hypoeutectic component is the FCC phase, and the hypereutectic component is primary The phase is Laves phase, and the microstructure of eutectic alloy is composed of BCC phase and Laves phase. The multi-principal alloy system of the present invention does not contain Al, Ti, Zr and other elements that react with the passivation of the quartz test tube, and Fe, Co, Ni, Sn elements can realize the supercooling and rapid solidification of the molten glass, and the non-equilibrium of the entropy alloy is studied in the study. solidification behavior. In addition, with the increase of Sn content in the present invention, the dual-hard BCC phase and the Laves phase generated by the transformation significantly improve the hardness and strength of the alloy. |
