Outline of Final Research Achievements

Sintering is a processing method to make complicated-shaped components by heating powder compacts. In order to understand and control the powder processing and sintering process, we used X-ray micromicrotomography to observe the microstructural evolution during sintering. The following results were obtained:1) A method to estimate the sintering stress and the bulk viscosity was proposed from the observation of pore structures in viscous sintering of glass particles. 2) The evolution of coarse pores in sintering of alumina powder was elucidated by X-ray micro tomography observation. The effect of the orientation of crystalline particles on anisotropic shrinkage was clarified. 3) The mechanical principles for the sintering of two particles and the shrinkage of a closed pore were proved by using computer simulations.
