Microstructural Nature of the Mechanical Properties of Sintered Materials

摘要

The theoretical aspects of microstructural nature of strength and fracture properties of iron based sintered materials are presented in the paper. Strengthening contributions of individual microstructural components and chemical composition are quantified. Special attention is paid to the influence of porosity on the mechanical properties in general, and theoretical models with analytical description are elaborated. Specific examples are presented on selected iron based sintered systems. The results allow the prediction of mechanical properties on the basis of porosity state and selected microstructural parameters.
