Abstract
Gold single crystals were deformed at room temperature to various amounts of deformation at different strain rates. The crystals were cut into several specimens, each of which was etched to remove an amount of the surface layer (0–416 μ,), and “recrystallized.” An effect of the surface on nucleation of recrystallized grains was found. The effect was most pronounced in crystals deformed to the end of stage II of the stress-strain curve. It is concluded that the surface itself has an effect which results in high dislocation density regions in its layers. Several mechanisms, by which the surface layers interfere with dislocations escaping from the surface, are discussed.
