  • Cold-pressing and vacuum arc melting of γ-TiAl based alloys 
    Mathabathe, Maria Ntsoaki; Bolokang, A.S.; Govender, G.; Siyasiya, Charles Witness; Mostert, Roelf Johannes (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 ...
  • Roughing of thick, coarse-grained high-temperature-processing steels processed via compact strip production 
    Banks, K.M. (Kevin); Tuling, Alison; Maubane, Dannis Rorisang Nkarapa (Iron and Steel Institute of Japan, 2017)
    The roughing conditions required to avoid local heterogeneous regions in the final microstructure of high temperature processing (HTP) Nb linepipe steels have been investigated for quasi-compact strip production (CSP) ...
  • The vacuum melted ɣ-TiAl (Nb, Cr, Si)-doped alloys and their cyclic oxidation properties 
    Mathabathe, Maria Ntsoaki; Bolokang, A.S.; Govender, S.; Mostert, Roelf Johannes; Siyasiya, Charles Witness (Elsevier, 2018-08)
    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 ...
