Investigation and optimization of heat treatment process on tensile behaviour of Ti6Al4V alloy

Author: Omoniyi, PO ; Mahamood, RM ; Arthur, Nana KK ; Pityana, Sisa L ; Akinlabi, SA ; Okamoto, Y ; Maina, MR ; Akinlabi, ET Date: Oct 2021 This article examines the microstructure and tensile strength of annealed Ti6Al4V alloy at different temperatures and times. Taguchi based L9 (32) design was used for the experimental design matrix and optimization of the tensile strength of ... Read more
Investigation of the mechanical and microstructural properties of TIG welded Ti6Al4V alloy

Author: Omoniyi, PO ; Mahamood, RM ; Arthur, Nana KK ; Pityana, Sisa L ; Akinlabi, SA ; Hassan, S ; Okamoto, Y ; Maina, MR ; Akinlabi, ET Date: Jul 2021 The joint integrity of 1 mm thick sheets of Ti6Al4V alloy welded autogenously using TIG welding was investigated in this article. The current and gas flow rate were varied and their effects on the mechanical properties and microstructure of ... Read more
Joint integrity evaluation of laser beam welded additive manufactured Ti6Al4V sheets

Author: Omoniyi, PO ; Mahamood, RM ; Arthur, Nana KK ; Pityana, Sisa L ; Skhosane, Besabakhe S ; Okamoto, Y ; Shinonaga, T ; Maina, MR ; Jen, TC ; Akinlabi, ET Date: Mar 2022 The feasibility of joining laser metal deposited Ti6Al4V sheets using laser beam welding was investigated in this article. The additive manufactured sheets were joined using a 3 kW CW YLS-2000-TR ytterbium laser system. The mechanical properties ... Read more
Optimization of laser-cladded SS316L/IN625 functionally graded material deposited on a copper substrate for boiler pipe heat exchanger applications

Author: Morake, JB ; Maina, MR ; Mutua, JM ; Olakanmi, EO ; Pityana, Sisa L Date: Dec 2023 Laser cladding is a surface modification method that can be employed in components under severe operating conditions, such as boiler heat exchangers, to mitigate degradation. However, poor clad quality hinders performance during service. This ... Read more c b
