  • Chauke, L; Möller, H; Curle, UA; Govender, G (2013-07)
    Anodising of aluminium alloys can be used to improve corrosion resistance during application or it can be simply for decorative purposes. In this research, anodising of 6111 (Cu containing) and 6082 (without Cu) alloys ...
  • Moller, H; Curle, UA; Masuku, EP (Editorial office of Transactions of Nonferrous Metals Society of China, 2010-09)
    Semi-solid metal (SSM) processing is a unique manufacturing method to produce near-net shape products for various industrial applications. The nature of the SSM slurry (with solid spherical grains suspended in a liquid), ...
  • Mazibuko, NE; Curle, UA (Trans Tech Publications, 2011-06)
    During rheo-high pressure die casting (R-HPDC) of Al-Zn-Mg-Cu alloys a coarse eutectic phase is formed. This eutectic phase is difficult to take into solution because of its size and it would require longer solution heat ...
  • Chauke, L; Moller, H; Curle, UA; Govender, S (Trans Tech Publications, 2012-10)
    Heat 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 ...
  • Chauke, L; Möller, H; Curle, UA; Govender, G (S2P 2012 (Semi-Solid Processing), 2012-10)
    Heat 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 ...
  • Curle, UA; Wilkins, JD; Govender, G (Hindawi Publishing Corporation, 2011)
    Industrial semi-solid casting trials of aluminum A356 brake calipers were performed over five days with the CSIR-RCS and highpressure die casting process cell. Consecutive visual passed castings were used as the measure ...
  • Müller, H; Masuku, EP; Curle, UA; Pistorius, PC; Knutsen, RD; Govender, G (Southern African Institute of Mining and Metallurgy, 2011-03)
    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), ...
  • Curle, UA; Wilkins, JD; Govender, G (Trans Tech Publications, 2013)
    Flexibility of the Council for Scientific and Industrial Research’s Rheocasting System (CSIR-RCS) and its rheo-high pressure die casting (R-HPDC) technology is again demonstrated, as with aluminium alloys, by processing ...
  • Curle, UA (Materials Science and Manufacturing, 2011-07)
    Wrought aluminium alloys are prone to hot tearing when cast into near-net shapes. This problem can be overcome by the novel casting technique of rheo-processing combined with high pressure die casting. An industrial engine ...
  • Curle, UA (Editorial office of Transactions of Nonferrous Metals Society of China, 2010-09)
    Flexibility of the CSIR-RCS, induction stirring with simultaneous air cooling process, in combination with high pressure die casting is successfully demonstrated by semi-solid rheocasting of plates performed on commercial ...
  • Curle, UA; Govender, G (Editorial office of Transactions of Nonferrous Metals Society of China, 2010-09)
    Near-net shape rheocasting with the Council for Scientific and Industrial Research Rheo casting system(CSIR–RCS) and a high pressure die casting machine was successfully performed on Al–5Ti–1B grain refined aluminum alloy ...
  • Curle, UA; Moller, H; Wilkins, JD (Elsevier, 2011-03)
    It is demonstrated experimentally that using the Council for Scientific and Industrial Research Rheo Casting System and high pressure die casting it is possible to semi-solid process and cast into a shape high purity ...
  • Curle, UA; Möller, H; Wilkins, JD (Elsevier, 2011-02)
    It is demonstrated experimentally that by using the Council for Scientific and Industrial Research Rheo Casting system and high pressure die casting it is possible to semi-solid process and cast into a shape unmodified ...
  • Curle, UA; Ivanchev, L (Editorial office of Transactions of Nonferrous Metals Society of China, 2010-09)
    Rheocasting of plates in Al alloy 359 reinforced with SiC at 11%, 27% and 50% (volume fractions) exhibits the capability of the council for scientific and industrial research-rheocasting system (CSIR-RCS) in rheo-processing ...
