A frequently employed experimental means for determining sintering mechanisms in solids has been the measurement of the rate of growth of a neck between two similar bodies during sintering. If these bodie

Such studies are conveniently classified into three categories, according to whether the observations are made (1) in reflection microscopy; (2) in transmission microscopy; or (3) by serial sectioning* techniques. The present paper avoids the dis

,„Damit Sie gerne wiederkommen!“,monly specified characteristic of powder metallurgy products, because, to a first approximation, mechanical properties are related to density. Often, however, this is a poor approximation due to the recognized fact that porosity, per se, does not determine the properties of the product; that is, at

https://doi.org/10.1007/978-3-642-83543-8The geometrical changes observed during the sintering of solid particles can be accounted for by a variety of atomic mechanisms, including various diffusional fluxes implicit in the geometry of the model systems, and shear processes involving pure slip of dislocations and climb or cross-slip controlled creep.
