Influence of Twin Thickness and Grain Size on the Tensile Behavior of Fully Nanotwinned CuAl Alloys
Source abstract
Abstract
In this study, the mechanical properties of fully nanotwinned Cu–2 wt%Al and Cu–6 wt%Al are evaluated by tension testing utilizing digital image correlation, allowing for the observation of local macroscopic deformation. By individually varying twin thickness, grain size, and composition, the isolated effect of each of these parameters on both strength and ductility is observed. Increased strength correlated with decreasing grain size or increasing Al content. It is observed that with decreasing twin thickness the ductility could be improved.
