Abstract

The effects of shot peening on the mechanical properties of a 2060 Al-Li alloy were investigated through tensile tests and microhardness tests on longitudinal sections of the specimens. Moreover, the microstructural evolution of the rolled (non-shot-peened) and shot-peened specimens was analyzed. Experimental results indicated that the phenomenon of work softening occurred due to shot peening. Therefore, the tensile strength, yield strength, and microhardness decreased, while the total elongation increased. Furthermore, microstructural analysis showed that softening effects were primarily ascribable to the partial dynamic recrystallization and textural transition from β to α fiber textures. These resulted from simultaneous influences of heat effect and plastic deformation during the shot peening process. Consequently, the dislocation density decreased while the weighted average of the Schmid factor increased, making the deformation easier and the material softened. As a result, the 2060 Al-Li alloy was softened by the relatively high-intensity shot peening, and an empirical equation was proposed to embody the comprehensive effects of the grain size and orientation on the mechanical properties of Al-Li alloys.
