  • Masuku, EP; Moller, H; Knutsen, R; Ivanchev, L; Govender, G (Trans Tech Publications, 2009-06)
    The traditional solution treatment cycles that are currently applied to rheo-processed A201 are mostly those that are used for conventional castings. These solution treatments are not necessarily the optimum solution ...
  • Moller, H; Govender, G; Stumpf, WE (2007-11)
    The 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 ...
  • Curle, A; Moller, H; Govender, G (Trans Tech Publications, 2013)
    The history of semi-solid metal forming and in particular rheo-high pressure die casting at the Council for Scientific and Industrial Research in South Africa is discussed. Processing flexibility is demonstrated on the ...
  • Masuku, EP; Moller, H; Govender, G; Ivanchev, LH (2008-09)
    Rheocasting of alloys A206 and A201 was investigated in this study. Conical bars with different silver contents were produced using CSIR rheoprocess technology, together with high pressure die casting. The results showed ...
  • 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 ...
  • Sha, G; Moller, H; Stumpf, WE; Xia, JH; Govender, G; Ringer, SP (Elsevier for Acta Materialia Inc and Pergamon, 2012-01)
    The solute nanostructures formed in the primary a-Al grains of a semi-solid metal cast Al–7Si–0.6Mg alloy (F357) during ageing at 180°C, and the age-hardening response of the alloy, have been systematically investigated ...
  • Moller, H; Govender, G; Stumpf, W (Trans Tech Publications, 2009-04)
    The T5 heat treatment of semi-solid metal (SSM) processed alloy F357 was investigated by considering the effects of cooling rate and natural aging after casting, as well as artificial aging parameters on tensile properties. ...
  • Moller, H; Govender, G; Stumpf, WE (Bentham Science Publishers, 2008)
    Semi-solid metal (SSM) processing is a unique manufacturing method to produce near-net shape products for various industrial applications. The aim is to obtain a semi-solid structure free of dendrites (which are formed by ...
