Résumé
Des tests simples et multiples d'action de compression uni-axiale sont pratiqués sur des métaux Al-Mg-Si et des alliages d'acier 0.02% Nb HSLA. Le degré de sensibilité à la vitesse, l'énergie d'activation et l'effet d'interruption de la déformation plastique des métaux sont déterminés.
Abstract
Single and multistage, uniaxial compression tests are conducted on Al-Mg-Si and 0.02% Nb HSLA steel alloys. Rate sensitivity, activation energy and the effect of interruption on the flow strength of the metals are determined.
