Numerical Simulation for Residual Stresses of the Spark Plasma Sintered Ti–TiB Composites
Spark plasma sintering (SPS) is an effective method for preparing the metal matrix composites. The residual stresses in the spark plasma sintered specimen are important factors affecting the mechanical properties and service properties of the composites. The stress distributions in the spark plasma sintered Ti–TiB composites with different Ti contents and different cooling rates were investigated in this paper, using the commercial software of ANSYS. The simulation results indicate that the residual stresses in the spark plasma sintered Ti–TiB composites decrease with increasing the Ti content in the composites. However, the cooling rate does not have an obvious effect on the residual stresses. The numerical simulation method is a useful and convenient method to study the residual stresses during the SPS process.
