Abstract
Maps of the strain tensor component εyy and profiles of the distribution of εyy along the length of the sample plotted by the method of digital image correlation are used to study the evolution of εyy and the width bb of the nucleating center, of the band nucleus and the band itself during tension of sample 1 of steel 08G2B exhibiting a high magnitude of the strain aging effect (SAE) after heating to Th = 250°C; the results are compared to the data for sample 2 (Th = 680°C) with low SAE. The experimental data obtained are used to reconstruct at the micro- (dislocation) level the process of formation and growth of the nucleating center and of the nucleus of the localized strain band emerging from it.
