Abstract
- The papers focusing on experimental and theoretical studies on sintering kinetics of real powder systems that were published in the 1940s–1950s are analyzed. Two major concepts explaining the nature of the so-called activity shown by metallic powders and some inorganic powders during sintering are addressed in detail. One concept deals with the key role of plastic flow mechanism and the other gives preference to the role of crystal lattice defects formed in powder particles when produced in nonequilibrium conditions. The reasons why neither of the concepts can underlie the physical theory of active sintering, being in full agreement with the experiment, are ascertained.
