Author:Müller, H; Govender, G; Stumpf, WEDate:Jun 2011Semi-solid metal high pressure die casting was used to produce plates from traditional wrought Al-Mg-Si alloys 6082 and 6004, as well as from traditional casting Al-Si-Mg alloys A356 and F357. The high Si-content of the casting alloys offer ...Read more
Author:Möller, H; Govender, G; Stumpf, WEDate:Jun 2011The natural and artificial aging responses of wrought and SSM-HPDC alloy 6082 are compared. It is shown that the heat treatment response of this Al-Mg-Si alloy is not influenced by differences in microstructures produced by different processing ...Read more
Author:Govender, G; Möller, HDate:2008In order for SSM forming to produce homogeneous properties in a casting, it is important that there is a uniform distribution of the primary grains. Besides producing a sound casting free of porosity, the amount of liquid segregation must be ...Read more
Author:Chauke, L; Moller, H; Curle, UA; Govender, SDate:Oct 2012Heat treatment of rheo-high pressure die cast (R-HPDC) A356 brake callipers has produced good mechanical properties on the laboratory scale. An industrial heat treatment is required to evaluate the applicability and conformance of the R-HPDC ...Read more

Author:Du Preez, WDate:Aug 2010This 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
Author:Möller, H; Govender, G; Stumpf, WEDate:Sep 2008The heat treatment cycles that are currently applied to semi-solid processed components are mostly those that are in use for dendritic casting alloys. These heat treatments are not necessarily the optimum treatments for non-dendritic ...Read more
Author:Govender, G; Ivanchev, LHDate:Oct 2005The SSM forming technology has demonstrated that it will be a competitive process for the manufacture of high quality, high volume components for the automotive industry in particular. The new slurry approaches to SSM forming has made the ...Read more
Author:Chou, HN; Govender, G; Ivanchev, LDate:2006SSM is now considered an established technology to produce high integrity near net shape components for the automotive industry in particular. Although it is used extensively in the automotive industry, very little attention has been given ...Read more
Author:Moller, H; Govender, G; Stumpf, WEDate:Nov 2007The heat treatment cycles that are currently applied to processed components are mostly those that are in use for traditional dendritic alloys. These heat treatments are not necessarily the optimum heat treatments for SSM processing. The T6 ...Read more
