Abstract
Formation of density gradients in green bodies during powder compaction and the resulting sintering distortion still poses a problem in the powder metal industry. Consequently, the design and optimization of powder metallurgical production processes is of paramount relevance to avoid these part defects in the green bodies. However, this technology is currently based to a large extent on expert knowledge. The numerical simulation based on the Finite Element Method (FEM), represents a cost and time-saving alternative in comparison to the "trial and error" method. With the help of FE calculations, powder compaction processes can be optimized in terms of reducing the density gradients and the resulting sintering distortion already in their development and design phase.
