Resistance to dislocation motion in copper-based solid solutions with a statistically disordered atomic distribution

Abstract

The stress σ_F due to friction forces in copper-based solid solutions was determined. Under the conditions of the procedure used to measure σ_F, on the basis of the half-wave hysteresis with polycrystalline samples, the value of d: σ_F = σ_F0 + K_Fd^-(1/2) where σ_F0 is the resistance to dislocation motion in an alloy having an infinite grain size, and K_F is a constant. It is shown that σ_F0 is governed by the interaction of moving dislocations with impurity atoms in the case of a statistically disordered atomic distribution. A study was made of the effects of various factors on σ_F and of the nature of the changes in σ_F0 caused by alloying.
