The fine-scale microstructure of an Al 5083 alloy sensitized at 373 K (100 °C) for 3, 7, 14, 30, 45, and 90 days has been investigated using transmission electron microscopy (TEM) to study the evolution of the β phase (Al 3 Mg 2 ) at grain boundaries. In fully sensitized Al 5083, the β phase (Al 3 M...
