Sintering as a result of defect structure

Abstract

Abstract Experimental results are presented and conceptions are developed for the qualitative understanding of the fast densification which is frequently observed in the shrinkage stage during the sintering of disperse one‐component compacts. They are based on a dislocation multiplication in the powder particle contact regions which is temporarily connected with the contact growth. Thus, a defect structure state is developed due to which it seems possible that the powder particles as a whole move into the pore space through alternating sliding and deformation processes and get densely packed.
