Phenomenology of Sintering and Modern Theoretical Concepts
For a quantitative estimate of the effect of the elementary processes on densification it is first necessary to describe them quantitatively as independent processes, after which one can attempt to establish (quantitatively) their interdependence and their effect on densification. The problem would be completely solved if it were possible to describe these processes on the basis of modern physical concepts of lattice imperfections and their part in the flow of a crystalline substance. However, as will be indicated below, the attempts made up to the present time have not been successful — at best they give some qualitative explanation, but no quantitative description.
