Zusammenfassung:	The present invention relates to a high entropy Ni-Fe-Cr-based alloy. According to one embodiment of the present invention, provided is the high entropy Ni-Fe-Cr-based alloy which comprises: 25-45 at% of Cr; 40-(95-Cr) at% of Ni; 5-(60-Cr) at% of Fe; and extra inevitable impurities. According to one aspect of the present invention, the alloy has an austenite single phase and excellent mechanical properties. 본 발명은 하이 엔트로피 Ni-Fe-Cr계 합금에 관한 것이다. 본 발명의 일 실시형태는 원자%로, Cr: 25~45%, Ni: 40~(95-Cr)% 및 Fe: 5~(60-Cr)%, 기타 불가피한 불순물을 포함하는 하이 엔트로피 Ni-Fe-Cr계 합금을 제공한다. 본 발명의 일측면에 따르면, 오스테나이트 단상을 가지며, 기계적 물성이 우수한 하이 엔트로피 Ni-Fe-Cr계 합금을 제공할 수 있다.
