Title: Numerical Predictions on the Final Properties of Metal Injection Moulded Components after Sintering Process

Abstract

A macroscopic model based on a viscoplastic constitutive law is presented to describe the sintering process of metallic powder components obtained by injection moulding. The model parameters are identified by the gravitational beam-bending tests in sintering and the sintering experiments in dilatometer. The finite element simulations are carried out to predict the shrinkage, density and strength after sintering. The simulation results have been compared to the experimental ones, and a good agreement has been obtained.
