Corrosion fatigue performance in simulated sea water of aluminium 6061-T651 welded using ER4043 filler wire

Author: Mutombo, K ; Du Toit, M Date: Oct 2010 The 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
Electrowinning molten titanium from titanium dioxide

Author: Van Vuuren, DS ; Engelbrecht, AD ; Hadley, TD Date: Oct 2005 The value chain of titanium products shows that the difference between the cost of titanium ingot and titanium dioxide is about $9/kg titanium. In contrast, the price of aluminium, which is produced in a similar way, is only about $1.7/kg. ... Read more
In search of low cost titanium: the Fray Farthing Chen (FFC) Cambridge process

Author: Oosthuizen, SJ Date: Oct 2010 This article explores the Fray Farthing Chen (FFC) Cambridge Process, a novel method for the electrochemical de-oxidation of metal oxides in molten salt, discovered at the University of Cambridge in 1997. The process was hailed as a highly ... Read more
Lighter, greener and strong: developing light metals for application in the aerospace industry

Author: Du Preez, W Date: Aug 2010 This presentation starts of by discussing the drivers of the international titanium industry, followed by drivers of the South African titanium industry. The Titanium Centre of Competence is then analysed. The conclusion is reached that the ... Read more
Mechanical properties of mill-annealed Ti6Al4V investment cast

Author: Mutombo, K ; Rossouw, P ; Govender, G Date: Jul 2011 Ti6Al4V alloy, produced by investment casting using yttria stabilized zirconia, was machined and then mill-annealed in vacuum furnace. The ultimate strength, yield strength and percentage elongation were largely improved compared to the same ... Read more
Microstructure and wear behaviour of Al/TiB2 metal matrix composite

Author: Popoola, AP ; Pityana, Sisa L ; Ogunmuyiwa, E Date: Oct 2010 Al/TiB2 metal matrix composite (MMCs) was fabricated on aluminium AA1200 with the aim of improving the wear resistance property of the substrate. The characterization of the MMCs was carried out by Optical Microscopy (OM), Scanning Electron ... Read more
