Surface Relaxation, Dynamics of Geometric Structure and Macrokinetics of Densification During Sinter monodispersed systems having a characteristic particle size value below 1 μm are considered. The possibility of essential surface relaxation of a system, in which the surface mass transfer process leads to a topologically continuous coarsening of geometric structure in the absence of rearrangement

Theoretical Analysis of Metal Particle Cooling in the Rotating Electrode Process from spherical droplets occurs during their flight through the helium inert atmosphere. Cooling times and solidification path lengths as well as the cooling rates were numerically calculated for the particle diameter range 50 — 600 μm, and initial velocity range 10.5 — 50 m/s.

Activated Sinteringallurgist. The term of activated-sintering may include a variety of “activating” mechanisms, ranging from mechanical activation to activation by a liquid phase. In this paper major activating mechanisms which results in solid state sintering from small amounts of impurities or additives will be desc

Dislocation-Activated Sintering Processesstribution and time-dependent alteration are able to be analysed by means of the Kessel-technique and described quantitatively. The same effect is observed during sintering compacts of electrolytic copper powder. The results of positron annihilation spectroscopy show the high dislocation densities g

The Dependence of Sinterability of Ni-Added W-Powder Compact on the Contact Neck Size of W-Particles obtained by a variation in the degree of presintering of the W-powder compact before Ni-addition. The sintering behaviour of the Ni-doped W-compact was investigated by measuring the sintering shrinkage and the electrical resistivity change..The sinterability of the Ni-doped W-compact depended on th
