Characterisation and monitoring of TI-6AL-4V Eli power used for the qualification of medical implants produced through additive manufacturing

Thejane, Kekeletso (Bloemfontein: Central University of Technology, Free State, 2018)

The characterisation and monitoring of Ti-6Al-4V extra low interstitial (ELI) powder is an important requirement for full qualification of medical implants and aerospace components produced through Selective Laser Melting ...
Determination of the fatigue properties of Ti6Al4V (ELI) parts built by a direct metal laser sintering system with standard process parameters followed by post-processing treatments

Malefane, Lerata Botsane (Bloemfontein : Central University of Technology, Free State, 2019-02)

Design of hard tissue medical prostheses is typically based on the mechanical properties of the materials used. However, apart from non-loadbearing implants, medical prostheses in use are exposed to various forms of dynamic ...
Variation of Impact Toughness of As-Built DMLS Ti6Al4V (ELI) Specimens with Temperature

Muiruri, A.M.; Maringa, M.; Du Preez, W.B.; Masu, L.M. (South African Journal of Industrial Engineering, 2018-11)

The response of direct metal laser sintering (DMLS) produced Ti6Al4V (ELI) to impact was investigated using an instrumented Charpy impact test machine and V-notch specimens. Impact toughness testing was conducted over the ...
