THE THEORY OF SINTERING BY VOLUME OR SURFACEDIFFUSION.
Abstract
A brief summary is made of the theory of the sintering of two spheres or of a sphere and a plane by either volume-diffusion or surfacediffusion. The previous theories of Kuczynski and Cabrera are considered and following an analysis of some of the approximations involved it is found that the growth of the major neck radius, X, with time, t, can be summarized by X to the nth power/ r to the mth power = At, where r is the sphere radius and n = 5, m = 2 for a volume-diffusion mechanism or n = 7, m = 3 for a surface-diffusion mechanism. A is a constant given in terms of the geometrical and physical constants for the two mechanisms and the two cases of sphere-plane and sphere-sphere sintering. (Author)
