Nanolayered CoCrFeNi/Graphene Composites with High Strength and Crack Resistance
Emerging high-entropy alloy (HEA) films achieve high strength but generally show ineludible brittle fractures, strongly restricting their micro/nano-mechanical and functional applications.Nanolayered (NL) CoCrFeNi/graphene composites are elaborately fabricated via magnetron sputtering and the transfer process.It is uncovered that NL CoCrFeNi/graphe
