Abstract Scope |
Cellular structures are characterized by the large percentage of porosity and therefore large surface area. Therefore, they are extensively used as catalysts and filters and biological interfaces. Besides, they provide high stiffness-to-weight ratio, a high energy absorption, and low heat conductivity with smart geometrical orientations.
In this work, a multi-physics model is developed starting from the thermodynamics analysis using Finite Element Method (FEM) and Computer Coupling of Phase Diagrams and Thermochemistry (CALPHAD) approach to predict then microstructure features. The proposed approach is applied for both cellular and bulk high-strength stainless steel alloy 17-4PH (Precipitation Hardening) structures to investigate the thermodynamics and kinetics of the transformation and its impact on the resulting microstructure. |
