Abstract Scope |
In the most recent decades, the demand of high-throughput calculations increases significantly for materials designs. An ICME (Integrated Computational Materials Engineering) framework is proposed to predict the solid solution strengthening of multicomponent systems. We adopted Walbrühl’s framework which is based on the concentration dependence of x^(2/3) as proposed by Labusch and fitted the coefficients with experimental and computational simulated results. Furthermore, we calibrated the model and optimized the parameters with over 1000 alloy systems, including a wide range of elements. The calibrated systems include pure metals, binary, ternary and multi-component high entropy alloys. The calibrated model gives a good agreement between the calculated and experimental values. The parameters have been implemented into the Thermo-Calc software to design alloys within the solubility range of the desired phases to obtain properties needed. |
