On the Mechanism of Grain Boundary Elimination from Sintering Neck

Abstract

To clarify the neck boundary elimination behavior (Wilson-Shewmon, 1966 and Alexander-Balluffi, 1957), a model sintering experiment was made using a rope specimen of copper wires. The relative configurations of sintering necks and neck boundaries were inspected on the polished sections of the sintered rope specimens. The neck boundaries were observed in most cases to be out of the minimum area sites, and often to have disappeared from the cross-sectional area. A possible mechanism of the neck boundary elimination has been proposed which takes into account a pulling force of the transverse grain boundaries.
