Deformation behaviour of aluminium low-micron MMCs and MMNCs at warm working temperatures (0.3—0.5 Tm)

Author: Gxowa, Zizo ; Chown, LH ; Govender, Sagren ; Curle, Ulyate Date: Oct 2016 This work evaluates the deformation behaviour, at warm working temperatures, of green particle-reinforced aluminium composites produced by powder blending in a high-energy ball mill. The work focuses on metal matrix composites (MMCs) based ... Read more c b
Effects of Ti and TiC ceramic powder on laser-cladded Ti-6Al-4V in situ intermetallic composite

Author: Ochonogora, OF ; Meacock, C ; Abdulwahaba, M ; Pityana, Sisa L ; Popoolaa, API Date: Dec 2012 Titanium metal matrix composite (MMCs) was developed on titanium alloy (Ti–6Al–4V) substrate with the aim of improving the hardness and wear properties by laser cladding technique using a Rofin Sinar 4 kW Nd: YAG laser. Wear investigations ... Read more
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
Impact toughness of laser surface alloyed Aluminium

Author: Mabhali, Luyolo AB ; Sacks, N ; Pityana, Sisa L Date: Mar 2012 Laser surface alloying of aluminium AA1200 was performed with a 4kW Nd:YAG laser and the impact resistance of the alloys was investigated. The alloying powders were a mixture of Ni, Ti and SiC in different proportions. Surfaces reinforced ... Read more
Improvement of the surface properties of aluminium by the formation of intermetallic phases and metal matrix composites during laser surface alloying

Author: Mabhali, Luyolo AB ; Pityana, Sisa L ; Sacks, N Date: May 2011 Aluminium is widely used in industry due to its low cost, light weight and excellent workability, but is lacking in wear resistance and hardness. Laser alloying is used to improve the surface properties, such as hardness, by modifying the ... Read more
Microhardness and wear behaviour of surface modified Ti6Al4V/Zr-TiC metal matrix composite for advanced material

Author: Popoola, API ; Ochonogor, OF ; Abdulwahab, M ; Pityana, Sisa L ; Meacock, C Date: Dec 2012 Surface modification of titanium alloy (Ti-6Al-4V) was made using a Rofin Sinar 4 kW Nd: YAG laser. A laser multi-track 50% overlapping process was employed to produce Zr and Zr-TiC metal matrix composite (MMC) coatings on Ti6Al4V substrate. ... Read more
Microstructure characterization of laser-deposited titanium carbide and zirconium-based titanium metal matrix composites

Author: Ochonogor, OF ; Meacock, C ; Pityana, Sisa L ; Popoola, PAI ; Dutta Majumder, J Date: Sep 2012 Laser metal deposition (LMD) is an additive manufacturing technique whereby a stream of metal powder is consolidated by a focused laser beam on the surface of a substrate or engineering component. The interaction zone between the laser beam ... 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
