Mechanism of Anisotropic Dimensional Changes During Sintering of Metal Powder Compact

  • Hidenori Kuroki

The dimensional change of a metal powder compact during sintering has been considered as one of the major parameters with which the mechanism of sintering can be described quantitatively. The changes, however, are anisotropic in a cold pressed compact. The value depends on the direction in which it is measured, i.e., the compacting one or the lateral one.
