In the present work, a metal-metal composite consisting of aluminum-magnesium alloy AA5083 matrix and nanocrystalline CoCrFeNi high-entropy alloy reinforcement particles in 12vol% was successfully friction deposited in multiple layers. The layer interfaces or the reinforcement/matrix interfaces show...
