The Kinetics of Contact Formation During Sintering by Diffusion Mechanismsacancy sinks into the contact region between the particles has been treated by numerous authors for models and powder aggregates. All these treatments, even the most sophisticated ones, suffer from approximative assumptions on the geometry of the neck or on the superposition of the various diffusion

Sintering Processeseramic material was initially made via the powder route. Modern applications of sintering in materials technology are widespread: powder-metallurgical production of structural steel parts, self-lubricating bearings, porous metals for filtering, tungsten wires for lamp filaments, and soft and hard ma

Computer Simulation of Sintering Processesaneously acting mechanisms (surface and grainboundary diffusion) are treated without simplifying assumptions concerning the neck geometry developed during sintering. The method is independent of the physical constants specific for the sintering material and normalised with respect to size which make

The Influence of Pressing on Sintering Kinetics of Spherical Particless is not yet possible. At present, the quantitative description of the sintering rate and the change of geometry of a system consisting of irregular particles of different size, arranged irregularly and deformed by cold pressing, seems to be a hopeless task. A possible approach is to consider the ef
