Computational Approach to Predict Phase Fraction in Dual-Phase High Entropy Alloys
Type and fraction of secondary phase play a significant role in determining the properties. For the first time, a computational method is used to predict the phase fraction in dual phase high entropy alloy systems. In this work, a new parameter δc(critical lattice distortion) is proposed. Valence electron concentration (VEC) and δc are used to predict phase fraction. To validate the model a series of AlxCoCrFeNi (x=0.3, 0.5, 0.7) alloy was synthesized by vacuum arc melting and analysed using x-ray diffraction and electron backscatter diffraction techniques. It is found that the experimental results agree closely with the predicted value.
