Computational Efficient Modeling of Supersolidus Liquid Phase Sintering in Multi-component Alloys for ICME Applications

Abstract One of the challenges in computational design pre-alloyed powders for sintering is absence predictive, efficient, and fast acting models that enable space alloys to be tractable. This study presents an efficient predictive model simulate densification as well shape distortion powder compacts during supersolidus liquid phase (SLPS). The combines generalized viscous theory with microstructural diffusional creep accommodated by grain boundary sliding. Critical parameters are obtained from thermodynamic modeling based on calculation diagrams (CalPhaD) simulations transformations metals. validated comparing simulation results experimental data literature various types engineering alloys. In addition, a processing window defect free samples presented defining softening parameter body. can used SLPS within context integrated materials (ICME) frameworks.
