Abstract

A new relation is proposed between the flow stress tau and the concentration c in relatively dilute solid solutions and precipitation hardened alloys: tau equals alpha square root of c multiplied by (times) (1 plus beta square root of c). Computer simulation indicates that the relation should be valid approximately for beta square root of c less than equivalent to 0. 5. The first term represents the well-known Friedel relation; the new term is due to first-order effects of the finite range of interaction between obstacles and dislocations. It also modifies the conventional linear relation between the reciprocal activation length and the flow stress as the concentration is varied.
