In the present study the repeated scrach tests were made on the (111) face of the αCu-Al single crystals in the <211> and <110> directional with a unidirectionl or reciprocating. Afer the (111) face had been scratched, the face was electropolished to remove a thin layer of suitable thickness. The slip systems and the each pit distributions were abserved on the exposed surfaces. The results obtained are as follows : (1) The deformations produced by scratch in the [2^^-11]direction are found to be more pronounced than those in the [21^^-1^^-] scratch. The active slip systems on both sides of the scratched track differ from those observed under the track. (2) The scratched tracks and the slip traces on the scratched faces and the dislocation distributions inside of the material show that the deformation produced by the unidirectional scratch is more remarkable than that produced by the reciprocating scratchs in both cases of <211>and <110> directions.
