title = "Effects of different temper and aging temperature on the precipitation behavior of Al 5xxx alloy",
abstract = "Al 5xxx alloys can become sensitized to intergranular corrosion (IGC) and stress corrosion cracking (SCC) because of the precipitation of intergranular β phase (Al3Mg2) when exposed to elevated temperature for sufficient time. In this study, ASTM G67 mass loss tests of Al 5083 H131, H116 and Al 5456 H116 aged at 323 K and 343 K for different times were conducted. The average grain size and grain boundary thickness of the three alloys were obtained from Electron Backscattered Diffraction (EBSD) images, and the classical nucleation theory was used to predict the precipitation behavior. Transmission Electron Microscopy (TEM) and Energy Dispersive X-ray Spectroscopy (EDS) were used to characterize Al 5083 H116 aged at different temperature for different times. Scanning Electron Microscopy (SEM) images of Al 5083 H131 etched for different times were used to evaluate the corrosion behavior of different grain boundaries.",
