抄録
The evolution of structural anisotropy in metallic hollow sphere (MHS) compacts during uniaxial compression in elevated temperatures is examined by experimentation as well as numerical simulation, in which an anisotropic continuum model for the compaction of powder packing is applied. The contacts between MHSs are enlarged with the reduction in the height of the compacts during firing, although the contact areas in the lateral direction are smaller than those in the vertical direction. The calculated results are in good agreement with the experimental data. A quasi-static compression test at room temperature for the sintered bodies is also conducted to reveal the correlation of their strength with the reduction in height during firing. It is shown that the bodies whose height is reduced over a certain value during firing have sufficient strength regardless of sintering temperature and time. Optimum sintering conditions to obtain firm MHS bodies can be estimated by the present method of simulation.
