Description:... Elevated-temperature compressive-strength test results from room temperature to 600 degrees F and creep test results from 350 degrees F to 500 degrees F are presented for V-groove edge-supported plates of 7075-T6 aluminum alloy. The test data are compared with calculations obtained from procedures for estimating maximum strength from material stress-strain curves and creep-failure stresses from isochronous stress-strain curves. The strength and creep results from this investigation are also compared with similar results from 2024-T3 aluminum-alloy plates.
