  • 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 ...
  • 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 ...
  • Ivanchev, L; Wilkinson, D; Govender, G; Du Preez, W; Bean, R (Academy of Science of South Africa, 2008)
    The latest trend in the automotive industry to produce fuel-efficient vehicles has resulted in the increased use of aluminium and magnesium alloys. Liquid metal high pressure die-casting (HPDC) currently satisfies the bulk ...
  • Ivanchev, L; Wilkins, D; Govender, G; Du Preez, WB; Bean, R (2006-02)
    The new trend in the automotive industry to produce more fuel-efficient vehicles has resulted in the increased use of aluminium and magnesium alloys. Currently liquid metal high-pressure die-casting (HPDC) fulfills 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 ...
  • Ivanchev, L; Camagu, ST; Govender, G (Trans Tech Publications, 2012-10)
    There are two main technologies for manufacturing of particulate reinforced metal matrix composites (MMC), solid state and liquid state processing. The great challenge of producing cast metal matrix composites is to prevent ...
  • 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 ...
  • 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 ...
  • Camagu, ST; Govender, G; Möller, H (Scientific Research Publishing, 2013-07)
    A method for producing metal matrix composites MMC was successfully implemented for mixing nano and low micron (“Hybrid”) sized SiC reinforcing particles in an aluminium alloy matrix. Due to the improved specific modulus ...
