Abstract
The strengths of porous bodies depend on the strength of the matrix and are a function of porosity content. In practice, such bodies are required to possess a limited amount of ductility if they are to be useful as engineering materials. A criterion for minimum acceptable ductility is proposed. This and a theory of strength of porous bodies are used to evaluate a maximum strength/porosity relationship for heat-treated steels. Experimental data are found to be in fair agreement with this relationship.
