  • Mathabathe, Maria Ntsoaki; Bolokang, A.S.; Govender, G.; Siyasiya, Charles Witness; Mostert, R.J. (Roelf) (Elsevier, 2019-12)
    Beta (β) solidifying γ-TiAl intermetallic alloys of nominal composition Ti-48Al, Ti-48Al-2Nb, Ti-48Al-2Nb-0.7Cr alloys have been cold pressed and vacuum arc melted. The Al loss was due to compaction method used prior to ...

    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 ...
  • Mathabathe, Maria Ntsoaki; Govender, S.; Bolokang, A.S.; Mostert, R.J. (Roelf); Siyasiya, Charles Witness (Elsevier, 2018-08)
    The γ-Ti-45Al-2Nb-0.7Cr-0.3Si based intermetallic alloy was developed. Microstructure evolution of the as-cast and heat-treated alloy yielded the spheriodised and Widmanstätten laths. High temperature differential thermal ...
  • Mathabathe, Maria Ntsoaki; Bolokang, A.S.; Govender, G.; Mostert, R.J. (Roelf); Siyasiya, Charles Witness (Elsevier, 2018-10)
    Structure-property relationship of the as-cast γ-Ti-45Al-2Nb-0.7Cr-0.3Si based intermetallic alloy was examined. The phases stable at room temperature in the alloy were γ/α2/Ti5Si3, respectively; while their crystal ...

    The γ-TiAl intermetallic alloy doped with Nb, Cr, and Si metals has been developed. It has emerged that the ternary Ti-48Al-2Nb and quinary Ti-48Al-2Nb-0.7Cr-0.3Si alloys yielded the best mechanical and cyclic oxidation ...
