Abstract

The possibility of parameterization of hot tensile data together with creep data is investigated, for Aluminium Alloy 7475-T7351. This study represents part of a broader research program aiming at the validation of a methodology recently proposed for analyzing both kinds of data together, considering different metallic materials. The results presented in Part 1 of this work, were analyzed according to 4 traditional methods of the literature for parameterization of creep data, namely: Larson-Miller, Orr-Sherby-Dorn, Manson-Succop and Manson-Hafferd. The compatibility of the hot tensile test results with those of creep is remarkably good, indicating the possibility of using both kind of data together also in extrapolation schemes. The criterion proposed for equivalence between hot tensile and creep data is verified to work well also for this kind of material, under the present experimental conditions.
