Influence of Mn on the tensile properties of SSM-HPDC Al-Cu-Mg-Ag alloy A201

Author: Müller, H ; Masuku, EP ; Curle, UA ; Pistorius, PC ; Knutsen, RD ; Govender, G Date: Mar 2011 A201 aluminium alloy is a high strength casting alloy with a nominal composition of Al-4.6Cu-0.3Mg-0.6Ag. It is strengthened by the O(Al2Cu) phase and the ’(Al2Cu) phase during heat treatment. Further strengthening of this alloy system can ... Read more
Influence of surface liquid segregation on corrosion behavior of semi-solid metal high pressure die cast aluminium alloys

Author: Masuku, EP ; Moller, H ; Curle, UA ; Pistorius, PC ; Li, W Date: Sep 2010 The aim of SSM forming is to obtain a semi-solid structure (which is free of dendrites) with the solid present in a near spherical form. The nature of the SSM slurry (with solid spherical grains suspended in a liquid), makes it susceptible ... Read more
Magnesium: origin and role in calcium-treated inclusions

Author: Pistorius, PC ; Presoly, P ; Tshilombo, G Date: Aug 2009 Steel was sampled after calcium treatment at an industrial steel plant, and the inclusions identified by energy-dispersive X-ray microanalysis (EDX) on polished sections of the samples analysing the samples in a scanning electron microscope. ...

Oxygen activity measurements in simulated converter matte

Author: Tshilombo, KG ; Pistorius, PC Date: 2007 The authors argue the possibility of using an oxygen probe to follow iron removal during converting, if local equilibrium is established between iron in the matte and the iron oxides in the fayalitic slag. The oxygen activity is expected to ... Read more
