Abstract
The activation energy for the intermediate sintering stage of powder injection molded 316L stainless steel were obtained by dilatermetric sintering experiments. The corresponding activation energy for relative density of 0.60, 0.65, 0.70, 0.75, and 0.80 are 351.46, 330.12, 279.17, 282.57, and 256.85kJ/mol. Results indicate that the sintering mechanism is dominated by volume diffusion mechanism at low relative densities. The higher activation energies obtained for powder injection molded specimens are due to the presence of binder residue and impurities on the particle surfaces after debinding.
