Compressive stress-strain test results for 7075-T6 aluminum-alloy sheet are presented for temperatures ranging from room temperature to 700° F and for exposure times from 0.1 to 100 hours. All specimens were loaded parallel to the rolling direction of the sheet and were tested at a nominal strain rate of 0.002 per minute. Stress-strain curves are presented for each temperature and exposure time investi-gated, and significant design data obtained from the curves (compressive yield stress, Young's modulus, secant and tangent moduli, and two stresses useful for determining the maximum compressive-strength of plates) are presented in graphical and tabular form. A time-temperature parameter derived from rate-process theory is used to present the com-pressive yield stresses as a single master curve.
