Creep and Creep Recovery of 2618-T61 Aluminum under Variable Temperature.

Abstract

Creep and creep recovery data are reported for pure tension of 2618 aluminum alloy under variable temperature between 200 deg. C and 230 deg. C. Varying temperature experiments involved an abrupt temperature increase and a linearly increasing and decreasing temperature at a constant stress of 137.9 MPa (20 ksi). A temperature-compensated time by Sherby and Dorn was employed to represent the effect of temperature. The temperature history dependent theory described the test data quiet well for both increasing and decreasing temperature. The apparent activation energy of this alloy was found to be 49,000 cal/mole.
