Abstract

In a paper entitled Mechanical properties in the initial stage of sintering (Journal of Materials Science 30 (1995) 1863), Arato, Besenyei, Kele and Weber have proposed a model to describe the Young's modulus of sintered materials as a function of porosity. The proposed model, even if it is able to predict actual experimental trends over a wide range of porosity, suffers from a theoretical inconsistency at zero porosity. Consequently, it should be used with care, and probably only in the initial stage of sintering, as indicated by the title of the article.
