    Microstructure Evolution and Compressive Property Variation of CoCrFeNiAlx High Entropy Alloys Produced by Directional Solidification

    CoCrFeNiAlx (x = 0.3, 0.6, 0.9 and 1.2, molar ratio) high-entropy alloys (HEAs) were prepared by directional solidification at the withdrawal rate of 70 µm/s and were simply referred to as Al0.3, Al0.6, Al0.9 and...
