Characteristics of laser In-situ alloyed titanium aluminides coatings

Author: Tlotleng, Monnamme ; Masina, Bathusile N ; Pityana, Sisa L Date: Jan 2017 The use of titanium aluminides as high temperature materials in the aerospace and automobile industries is becoming a reality since their early research and development in 1955. Their mechanical properties at elevated temperatures make them ... Read more
A comparative study on the sintering and casting of a blended elemental Ti-6Al-4V alloy

Author: Masikane, M ; Chikwanda, HK ; Sigalas, I Date: Jul 2015 Over the past years, the blended elemental powder metallurgy (PM) approach has been identified as one of the most promising strategies to reduce the cost of titanium-based components. However, oxygen pick-up, inhomogeneity of the microstructure ... Read more
Effects of heat-treatment on the microstructure of TiAl-Nb produced with laser metal deposition technique

Author: Tlotleng, Monnamme ; Lengopeng, Thabo ; Seerane, Mandy N ; Pityana, Sisa L Date: Oct 2017 Ti and its intermetallic alloys are light-weight and have good creep properties. Materials of this nature are desired for the manufacturing of parts for the aerospace, automotive and power plants. Titanium aluminides, in particular, are ... Read more
Evaluation of the microstructure and microhardness of laser-fabricated titanium aluminate coatings

Author: Tlotleng, Monnamme ; Lengopeng, T ; Pityana, Sisa L Date: Oct 2016 Titanium aluminide intermetallics are very brittle at room temperature, hence they are challenging to fabricate even by conventional manufacturing techniques such as casting and forging. The production of TiAl from elemental powders using ... Read more
Reinforcement of 2124 Al alloy with low micron SiC and nano Al2O3 via solid-state forming

Author: Gxowa, Z ; Camagu, ST ; Govender, S ; Pereira, MF Date: Jul 2015 A powder metallurgical process was used to fabricate Metal Matrix Composites (MMCs). A 2124 aluminium alloy was reinforced with 5 and 10 vol. % of Al2O3 (40-70nm) to form Metal Matrix Nano Composites (MMNCs) as well as 10 and 15 vol. % of SiC ... Read more
