An integrated computational materials engineering (ICME) based approach for designing sintered materials is presented. Development of the design method follows the materials systems approach that integrates processing, structure and property relationships for powder-based processing technologies including additive manufacturing. It includes an evolutionary algorithm to optimize the chemical composition and processing parameters to simultaneously improve the sintering response and the resultant properties. Thermodynamic simulations, based on the CALPHAD method, are used to establish microstructural constraints through phase stability at equilibrium. The importance of fast acting reduced order models to explore the multi-dimensional design space of materials will be discussed. To demonstrate the capability of the method, design exercises of novel pre-alloyed powders for various applications are shown. We show that new alloys with improved sintering performance can be designed while simultaneously enhancing properties by independently controlling composition and processing parameters.
