Abstract

Plane-strain compression tests were made on age-hardened Al-4 pct Cu single crystals of various orientations. The resulting stress-strain curves showed much less anisotropy than would be expected from single-phase crystals under the same conditions of testing. The data are explained by a model in which compatibility is maintained between the matrix and the precipitate platelets, the platelets both deforming and rotating. This model predicts that normally weak orientations are strengthened more by precipitation than normally hard orientations.
