| Abstract Scope |
In the present work, the densification behavior of boron carbide (B4C) and tungsten carbides (WC) during consolidation by spark plasma sintering (SPS) technology was analyzed. The specimens were processed under various temperature and pressure conditions and characterized in terms of relative density, grain size, and mechanical properties. Moreover, the conducted studies and the experimental data allowed extrapolation of the constitutive parameter for these carbide materials. These constitutive parameters were incorporated in a model based on the continuum theory of sintering that can predict the porosity/density and grain growth evolution and distribution during the sintering process. The model was used to determine the optimal condition for the sintering process to achieve the maximum theoretical density while minimizing the grain growth for both boron carbide and tungsten carbide. |
