Influence of the Total Porosity on the Properties of Sintered Materials—A Review

Porosity is a characteristic present in most sintered materials, full densification only being achieved special cases. For some porosity indeed desired characteristic, serving for the intended application of material. In any case, materials can have strong effect on their properties, both structural and functional. this paper, expressions proposed to describe influence total effective properties are examined. Moreover, universal expression (with two fitting parameters) valid satisfactorily represent all analysed behaviours proposed. One these parameters be assimilated tap powders used manufacture The examined were elastic moduli, ultimate strength, thermal electrical conductivities, magnetic characteristics, other directly related ones. study metallic ceramic, with homogeneous non-texturised microstructure.
