The effect of post weld heat treatment on the corrosion behaviour of a AA2050T34-FSW
… function of post weld heat treatment condition. Immersion tests in 0.1 M Nac1 and G110 intergranular tests were performed and the corrsion morphology and the depth of attacks in the different regions of the weld were investigated using FEG/SEM. Polarisation measuresments in the different regions …

Evaluating Leachability of Residual Solids Generated from Unconventional Shale Gas Production Operations in Marcellus Shale
… to both single extraction (i.e. Shake Extraction Test, SET) and multiple extraction (i.e. Immersion Test, IT) leaching tests. For the shake extraction test, samples were mixed with a specific amount of leaching solution without renewal over a short time period. In the immersion test, samples were …
