| Abstract |
Tensile strength, yield strength and elongation of aluminum and 2024 aluminum alloy strips were measured with various tensile directions to the rolling direction. Their preferred orientations were also determined using a pole figure device. A simple method of analysis was suggested for qualitative correlation between planar anisotropy of yield strength and preferred orientation of strip specimens. The analysis was made on the basis of an assumption that the yield stress is inversely proportional to an arithmetical average of Schmid factors for all slip systems. For cold rolled aluminum and recrystallized aluminum strip specimens, directionality of yield strength was qualitatively in agreement with the result analyzed by the method. For 2024-T4 aluminum alloy, the longitudinal tensile properties were superior to the transverse properties due to mechanical fibering. |
