We report the influence of strontium on the evolution of microstructural damage during tensile deformation of hot-rolled AZ31 alloys tested parallel to the rolling, transverse, and diagonal directions using a 4D (3D X-ray tomography plus time) technique. X-ray computed tomography images were collect...
