Abstract:
Spark plasma sintering (SPS) technology is used to sinter a large range of materials in a very short time. One of the challenges of using this process is to control the final dimension of complex shaped parts. In order to predict the compaction of the powder during a SPS cycle, we develop numerical models which take into account several physical laws involved during sintering such as creep behavior at high temperatures (viscoplasticity). In this study, the deformation model is fitted on an experimental densification curve of a nickel-based superalloy and implemented via the Abaqus® software in a thermal-electrical-mechanical model of the SPS process. A comparison of the numerical outputs with the experimental data shows a good agreement. The results demonstrate the capability to simulate accurately the sintering of powder with a limited number of experimental adjusted parameters compared to literature and to decrease significantly simulation run-time.
