Comparison of in situ alloyed Ti-6Al-4V+10Mo via selective laser melting and directed energy deposition

Author: Madikizela, C ; Cornish, LA ; Chown, LH ; Möller, H ; Arthur, Nana KK Date: Nov 2017 In situ alloying is an important topic for alloy development and improvement of mechanical properties in additive manufacturing. With the scarcity of getting most commercial titanium alloys in powder form, development and qualification of ... Read more
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
Microstructure and mechanical properties of selective laser melted Ti-3Al-8V-6Cr-4Zr-4Mo compared to Ti-6Al-4V

Author: Madikezela, C ; Cornish, LA ; Chown, LH ; Moller, H Date: Feb 2019 Beta Ti-alloys are known for their high fracture toughness and ductility, and are used in applications where these properties are needed, such as the aerospace and biomedical industries. The selective laser melting of the alpha + beta Ti-6Al-4V ... Read more
Warm temperature (170-280°C) uniaxial compresion of SiC reinforced MMCs

Author: Gxowa, Zizo ; Chown, LH ; Govender, Gonasagren Date: Oct 2017 This work evaluates the effect of warm temperature (170-280°C) uniaxial compression on the deformation behaviour of SiC reinforced Metal Matrix Composites (MMCs). Green and sintered compacts (d=8mm, h=12mm) were produced by blending 2124-Al ... Read more
