Relations of Porosity to Young's Modulus and Tensile Strength and Correlations between Those Mechanical Properties of Sintered Steels

Young's modulus (E) and tensile strength (S) of sintered steels depend mainly on porosity (P). The Es.0 and bE are affected by pore characteristic, such as pore shape, size, and interconnection, and So, SSUL, and bs depend on not only the pore characteristic but also metal matrix structure. The fitting curves of shear modulus and 0.2% proof stress used by the above relation of P also correspond to the measured values of them, respectively.
