    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 ...
  • Masuku, EP; Moller, H; Curle, UA; Pistorius, PC; Li, W (Editorial office of Transactions of Nonferrous Metals Society of China, 2010-09)
    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), ...
  • Pistorius, PC; Presoly, P; Tshilombo, G (2009-08)
    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 ...
  • Tshilombo, KG; Pistorius, PC (South African Institute of Mining and Metallurgy, 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 ...
