摘要：
The studies on deformation and diffusion processes during sintering are analyzed. Attention is paid to the effect of compressive and tensile stresses on shrinkage of silver, copper, and nickel powders. Superplastic deformation and displacement of particles as a whole are observed during shrinkage. Self-diffusion in transition metal carbides as well as their creep and neck growth during sintering are widely studied. The theory of effective diffusion coefficient is developed to be applied to diffusion-controlled processes in interstitial phases. The proposed relationships are shown to be applicable to creep and neck growth during sintering. Areas of further nanoscale studies are discussed.
