Abstract

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 - k_EP)², and v = (v₀ - v_sub)(l - k_vP)² + v _sub, where subscript 0 means P = 0, and P_1-3, k _E, k_v and v_sub 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.
