The effect of laser shock processing on the anti-corrosion performance of LENS-Fabricated Ti-6Al-4V alloy

Author: Arthur, Nana KK ; Kubjane, SM ; Popoola, API ; Masina, Bathusile N ; Pityana, Sisa L Date: May 2023 Titanium alloys are prone to increased oxidation rates when exposed to higher temperatures during application. As a result, the components suffer mechanical failure due to the formation of the alpha-case layer at 500 °C. To improve its corrosion ... Read more
The effects of LENS process parameters on the behaviour of 17-4 PH stainless steel

Author: Mathoho, Ipfi ; Akinlabi, ET ; Arthur, Nana KK ; Tlotleng, Monnamme ; Makoana, Nkutwane W Date: Feb 2020 17-4 PH stainless steel has proven to be one of the workhorse materials in industries such as aerospace, chemical, and energy. The attraction of this alloy to the aforementioned industries is derived from the fact that 17-4 PH stainless steel ... Read more
Influence of Mo on microstructure and nanoindentation hardness of Ti-Al-Si-xMo alloy processed by Laser Engineered Net Shaping (LENS)

Author: Raji, SA ; Pityana, Sisa L ; Popoola, API ; Popoola, OM ; Arthur, Nana KK ; Tlotleng, Monnamme Date: Oct 2021 In this work, the microstructure and nanoindentation hardness properties of Ti-Al-Si-xMo alloys produced through laser in-situ alloying using laser engineered net shaping (LENS) technology were investigated. The microstructures and phases ... Read more
Residual stress modelling and experimental analyses of Ti6Al4V ELI additive manufactured by laser engineered net shaping

Author: Ngoveni, AS ; Popoola, API ; Arthur, Nana KK ; Pityana, Sisa L Date: Mar 2019 This paper focus on the experimental analyses and modelling of the residual stresses build up during laser additive manufacturing by Laser Engineered Net Shaping. Currently, additive manufactured parts employ heat treatment for the reduction ... Read more
