Alpha case formation mechanism in Ti-6Al-4V alloy investment castings using YFSZ shell moulds

Bauristhene, A.M.; Mutombo, Kalenda; Stumpf, Waldo E. (Southern African Institute of Mining and Metallurgy, 2013-04)

Ti-64, which accounts for more than 50% of the worldwide titanium tonnage, has found commercial importance in industries requiring components with high specific strength and resistance to corrosion. Investment casting ...
Corrosion fatigue behaviour of aluminium alloy 6061-T651 welded using fully automatic gas metal arc welding and ER5183 filler alloy

Mutombo, Kalenda; Du Toit, Madeleine (Elsevier, 2011-12)

The fatigue life of aluminium 6061-T651 at various applied stress amplitudes in the unwelded and welded condition was found to be significantly reduced on immersion in a 3.5% NaCl simulated sea water solution, compared ...
Preparation and microstructural characterization of the 60Al- 40V master alloy

Mapoli, Tresor Okabo; Annan, Kofi Ahomkah; Siyasiya, Charles Witness; Mutombo, Kalenda (IOP Publishing, 2019-11-09)

The present study focused on preparation and characterization of 60Al-40V master alloy which was produced via aluminothermic process. The study assessed the production in order to provide the optimum Al requirement for ...
