Study on Mechanical Properties and Microstructure of FeCoCrNi/Al Composites via Cryorolling

Aluminum matrix composites (AMCs) reinforced by 1.5 and 3 wt% FeCoCrNi high-entropy alloy particles (HEAp) were obtained a stir casting process. The AMCs strip was further prepared room temperature rolling (RTR, 298 K) cryorolling (CR, 77 K). mechanical properties of the produced RTR CR studied. effect microstructure on analyzed scanning electron microscopy (SEM). results show that can greatly improve HEAp/AMCs. Under 30% reduction, ultimate tensile strength (UTS) HEAp/AMCs 120.3 MPa, but it increased to 139.7 MPa in composites. Due volume shrinkage effect, bonding ability reinforcement with Al stronger, exhibiting higher properties.
