Evaluation of HEBM Mechanical Alloying of Al2O3— 356/7075 Powder Mixture

Author: Govender, G ; Ivanchev, L ; Burger, H ; Mulaba, A ; Chikwanda, H Date: Apr 2012 Particle reinforced aluminium alloy metal matrix composites (MMC) have proven to be one of the advanced materials capable of replacing conventional structural alloys. However, the demand for such materials has been confined to high cost ... Read more
Hardfacing of aluminium alloys by means of metal matrix composites produced by laser surface alloying

Author: Pityana, Sisa L Date: Jun 2009 Metal matrix composite layers were formed on an aluminium substrate by means of laser surface alloying method. Aluminium 1200 was used as a host material and TiC particles were used as the reinforcement. The microstructure of the modified ... Read more
Nd: YAG laser treatment of aluminium-TiB2 coated: optimization of corrosion properties

Author: Popoola, PAI ; Pityana, Sisa L ; Fedotova, T ; Popoola, OM Date: Jun 2011 As the reports in the literature regarding corrosion performance of Al/TiB2 MMC are rather contradictory, the optimization of laser surface alloying parameters for these composite coatings seems to be necessary. The characterization of the ... Read more
Semi-solid high pressure die casting of metal matrix composites produced by liquid state processing

Author: Ivanchev, L ; Camagu, ST ; Govender, G Date: Oct 2012 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 agglomeration of ... Read more
