A study was made of the anisotropy in the tensile properties of 5083-0 aluminum alloy plates of thickness 22 and 80mm. Specimens with round and rectangular cross sections were prepared in the longitudinal (L), long transverse (LT) and short transverse (ST) directions. The principal results obtained are as follows.
(A) Results for 22mm thick plates: (1) Approximately same tensile strength, σB, was obtained in both the L and LT directions, but specimens with a round cross section showed slightly higher σB than those with a rectangular cross section. (2) Specimens in the LT direction showed appreciably lower 0.2% proof stress, σ0.2, than those in the L direction. (3) Round specimens in the L direction displayed consistently lower elongation, δ, but almost the same value of δ was obtained for rectangular ones in the L and LT directions and round ones in the LT direction.
(B) Results for 80mm thick plates: (4) Changes in the tensile properties were observed with the location in the thickness direction when the specimens were tested in the L direction. The specimens taken from the outer layer showed slightly lower σB and σ0.2 and slightly higher δ than those from the center. (5) The values of σB, σ0.2 and δ did not change with the location in the thickness direction when tested in the LT direction. (6) The mean values of σ0.2 and δ for the round specimens in the L direction taken from four different locations in the thickness direction were virtually identical with those for the large specimens of 80mm thickness. (7) Specimens in the ST direction showed considerably low δ while they showed approximately the same σB and σ0.2 as those in the LT direction.
