The influence of porosity (P) on Young's modulus (E) and Poisson's ratio of sintered steels produced from four types of steel powders was investigated. The values of E and depend mainly on the value of P, and those were a little affected by alloying elements. The relationships between E, , and P were described as following equations: and , where subscript 0 means P = 0, and and are empirical constants. These approximate equations showed good agreement with empirical results.
