During the sintering of powder compacts, non-uniform shrinkage occurs due to the density variation, inclusions, and other heterogeneous factors, resulting in distortion, warpage, and cracks. In this research, a constitutive relationship for describing solid phase sintering behavior is presented based on a linear-viscous incompressible model. The thermal deformation caused by uniform heating, which varies with time, is also considered. Shrinkage prediction during sintering processing is calculated by using the finite element analysis (FEA) software package ABAQUS. The constitutive model is implemented as a user subroutine with the temperature and density dependent material parameters. Measurements of an in situ axial dilatometer have been performed for a cylindrical bronze sample. The data compare reasonably well with simulated results. This effort is aimed to predict the distortion and to further improve the dimensional accuracy of sintered products.
