EBSD characterisation of the B2 orientation in -TiAl based alloy

Mathabathe, Maria Ntsoaki; Bolokang, A.S.; Govender, G.; Siyasiya, Charles Witness; Mostert, Roelf Johannes (IOP Publishing, 2019-11-09)

Electron backscattered diffraction (EBSD) has been conducted to determine the orientation relationship of the remnant B2 phase in an -solidified -Ti-45Al-2Nb-0.3Si (at. %) based intermetallic alloy. The morphology and ...
The effect of soaking time on mechanical properties of roll-bonded AA3003 and AA4045 used for heat exchangers

Moema, Joseph; Siyasiya, Charles Witness; Morudu, Veronica K.; Buthelezi, Thokozani (MDPI, 2023-09)

Due to the rising need for energy saving, high-performing automotive heat exchangers, demand has significantly grown in recent years. As a result, effective fin-tube heat exchangers are becoming more popular. These tubes ...
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. ...
