Features of local inelasticity distribution in D16T aluminum alloy under static tensile conditions

We have assessed the characteristic of local inelasticity distribution, which controls the evolution of microstructural processes in a loaded surface layer of D16T structural aluminum alloy specimen in view of the strain-hardening stages and deformation mechanism changeover. The deformation stages for static tensile conditions are correlated with the characteristic of local inelasticity distribution, in order to determine the relationship between the deformation mechanism changeover and local inelasticity kinetics for the transition point from strain-hardening to strain-softening of the alloy under study.
