Phase, microstructure and mechanical properties evaluation of AlCoCrFeNi high-entropy alloy during mechanical ball milling

The phase transition, microstructure evaluation and mechanical properties of AlCoCrFeNi alloy during mechanical ball milling were studied. The results show that the content of FCC phase decreases gradually with increasing milling time to 20 h. The amorphous phase can be obtained completely when extending the milling time to 84 h. The phase composition of the sintered AlCoCrFeNi alloy exhibits the trend opposite to that of the alloy powder after...
