Dislocation-Activated Sintering Processes

  • Chapter

Abstract

On sphere-plate models made from copper it is shown that during sintering the dislocation density increases considerably in the contact region. Its distribution and time-dependent alteration are able to be analysed by means of the Kessel-technique and described quantitatively. The same effect is observed during sintering compacts of electrolytic copper powder. The results of positron annihilation spectroscopy show the high dislocation densities generated in the heating phase to be reduced by non-conservative dislocation movement in the stage of intensive shrinkage. Resulting densification mechanisms are discussed.
