摘要：The Al0.5CoCrCuFeNi high-entropy alloy was synthesized by the medium frequency induction melting furnace. The effect of electromagnetic stirring on the microstructure and mechanical property of the alloy was investigated. The results showed that the electromagnetic stirring was effective to refine the grains for Al0.5CoCrCuFeNi alloy. And the alloy exhibited excellent mechanical properties. The as-cast rod sample did not fracture even at a compressive engineering strain of above 50%. Besides, the compressive strength and the tensile strength of the alloy with electromagnetic stirring during solidification were higher than that without electromagnetic stirring. Due to the existence of microcracks, the tensile engineering strain of the alloy reduced a little with electromagnetic stirring, but was still higher than 25%. (C) 2011 Published by Elsevier Ltd.
