Model to Describe the Elastic Modulus of Sintered Materials

Abstract

It is shown experimentally that a simple relation exists between the normalized elastic modulus, E/Em, and the normalized electrical conductivity, γ/γm, for sintered metallic materials. A model established originally to describe the change in electrical conductivity of sintered materials with porosity is extended to include the elastic modulus. This model is based essentially on the concept of the number of contacts between powder particles. Nous avons constate experimentalement qu'il existe une relation simple entre le module d'elasticite relatif, E/Em, et la conductivite electrique relative, γ/γm, pour les materiaux metalliques frittes. Un modele theorique precedemment etabli pour decrire l'evolution de la conductivite electrique des materiaux frittes a ete etendu au module d'elasticite. Ce modele est essentiellement base sur la notion de nombre de contacts entre les particules de poudre.
