Author:Mutombo, K; Du Toit, MDate:Oct 2010The fatigue life of Al6061-T651 for various applied stress amplitudes in the unwelded and welded conditions was significantly lower in 3.5% NaCl simulated sea water solution, compared to that in air. The damage ratio increased with a decrease ...Read more
Author:Moller, H; Masuku, EPDate:2009Semi-solid metal processing results in liquid segregation at the surface of the components. The pitting behaviour of this surface layer of semi-solid metal processed alloy F357 was compared with the centre (or bulk) of cast plates in 3.5% ...Read more
Author:Mutombo, KDate:Jul 2011The polished 6061-T651 aluminium alloy was immersed in 3.5% NaCl solution with about 7 ppm dissolved oxygen. Scanning Electron Microscopy equipped with Energy dispersive Xray Spectroscopy revealed the presence of Al-Si-Fe-containing particles ...Read more
