Abstract
In the same sintering and heat-treated conditions, the effects of partially alloyed and prealloyed powders with the different contents of alloying elements and compacting pressure on the Young's modulus (E) and Poisson's ratio (v) of sintered low alloy steels were investigated. The values of E and v depended mainly on the porosity (P) controlled by compacting pressure, and those values were affected slightly by the alloy powder types. The relations of P to E and v were described as the following equations: E = E0 (1-kE · P) 2 and v = 0.034 (1-kv · P)2 + 0.267, where E0 was the value of E at P = 0, and kE and kv were experimental constants that depends on the alloy powder types and sintering temperature.
