The A1-2.79Li-1.3Cu-0.7Mg-0.12Zr(8090) alloy has excellent resistance to intergranular and exfoliation corrosion as naturally aged, worst as peak aged and rather better as underaged than as overaged. The corrosion behaviour of the alloy is closely dependent on its microstructure. Under the peak agin...

The structure and transport properties in molten NaF have been studied using the method of molecular dynamics simulation. The calculations are based on two models of interionic potentials, which are Fumi-Tosi potential (FT) and the Fumi-Tosi potential without Van der Waals attractive item (FT). The ...
