Low-cycle fatigue behaviour of titanium-aluminium-based intermetallic alloys : a short review

Ellard, John J.M.; Mathabathe, Maria N.; Siyasiya, Charles Witness; Bolokang, Amogelang S. (MDPI, 2023-08)

Over the past decade, relentless efforts have brought lightweight high-temperature γ-TiAl-based intermetallic alloys into real commercialisation. The materials have found their place in General Electric’s (GE) high bypass ...
Powder characteristics blending and microstructural analysis of a hot-pack rolled vacuum arc-melted γ-tial-based sheet

Ellard, John J.M.; Mathabathe, M.N.; Siyasiya, Charles Witness; Bolokang, A.S. (Southern African Institute for Industrial Engineering, 2022-11-11)

In the quest for cost-effective fabrication processes capable of producing sound γ-TiAl products, the microstructure and mechanical properties of a modified second-generation hot-rolled γ-TiAl-based alloy with nominal ...
Vacuum melting of compressed powders and hot rolling of the as-cast Ti-48Al-2Nb-0.7Cr-0.3Si intermetallic alloy : mechanical properties and microstructural analysis

Ellard, John J.M.; Mathabathe, M.N.; Siyasiya, Charles Witness; Bolokang, A.S. (Elsevier, 2023-09)

The amalgamated effect of hot-rolling, rapid cooling and heat treatment on the grain refinement and the resultant mechanical properties of an intermetallic sheet of nominal composition Ti-48Al-2Nb-0.7Cr-0.3Si was investigated. ...
