Abstract
The problems induced by the inhomogeneity of deformation of alloys with high solute concentration are discussed using experimental results on Cu-2...10% Ni and Cu-30% Zn single crystals. Combining microscopic observations (etch-pit/stress-pulse method) with mesoscopic studies (microcinematography of slip line formation) and with macroscopic measurements (stress relaxation) in terms of the effective activation volumes, it is inferred that theories on the motion of a dislocation across the obstacle field in the slip plane can be compared with microscopic (etch-pit) results, while the macroscopic deformation kinetics and the critical resolved shear stress in the yield region of inhomogeneously deformed alloys might rather be controlled by the transfer process of slip to neighbouring slip planes.
