Abstract
During sintering with the participation of a liquid phase Al-Cu powder solids experience growth deformation in the first stage and shrinkage in the second. When the copper concentration in the mixture does not exceed the limit of solid-phase solubility at the sintering temperature, powder solids experience only growth; when the liquid phase is preserved during the whole period of sintering, growth is replaced by shrinkage. The growth of such powder solids during liquid-phase sintering is due to diffusion of copper atoms from the melt into aluminum particles, with the formation of solid solutions in these particles and of a liquid phase at grain boundaries. The deformation of powder solids in the shrinkage stage is brought about by dissolution of particles of the solid phase in the liquid and the particle regrouping process. The sign and magnitude of the deformation of powder solids during liquid-phase sintering are determined by Eq. (1).
