The influence of porosity (P) on Young's modulus (E) and Poisson's ratio (u) of sintered steels produced from four types of steel powders were investigated. The values of E and v depends mainly on the value of P, and those were a little affected by alloying elements. The relationship between compacting pressure (CP) and P and the relationships between E, v, and P were described as following equations: P = P1 + P2 exp(- CP / P 3), E = E0 (1 - kEP)2, and v = (v0 - vsub)(l - kvP)2 + v sub, where subscript 0 means P = 0, and P1-3, k E, kv and vsub were empirical constants. It was clarified that if powder and sintering temperature is defined, the elastic moduli of sintered steel can be calculated as a function of compacting pressure.
