Abstract
Microstructure changes, particle growth and the rate of densification during sintering of Cu-Ag in the presence of a liquid phase have been observed. Rapid densification occurred in the early stage of sintering, and more rapidly as the amount of liquid phase and temperature increased.
Particle growth by the solution-precipitation process was observed in this system. In a large amount of liquid, particles were larger in initial stage and smaller in final stage than in a small amount.
Using spherical copper powders, it has been found that the starting particles was disintegrated into smaller particles.
