Metallurgical characteristics of laser peened 17-4 PH SS processed by LENS technique

Author: Mathoho, Ipfi ; Akinlabi, ET ; Arthur, Nana KK ; Tlotleng, Monnamme ; Masina, Bathusile N Date: Mar 2019 This study investigated the effect of laser peening on the surface integrity (surface roughness, microstructure and microhardness) of 17-4 PH stainless steel components which were built through the direct energy deposition (DED). Additive ... Read more
Microstructure and microhardness characterization of Cp-Ti/SiAlON composite coatings on Ti-6Al-4V by laser cladding

Author: Sibisi, PN ; Popoola, API ; Kanyane, LR ; Fatoba, OS ; Adesina, OS ; Arthur, Nana KK ; Pityana, Sisa L Date: Mar 2019 Failure of engineering components on application is mainly a result of poor surface behavior of materials under certain conditions. Titanium and its alloys have numerous beneficial properties including light weight, high strength and excellent ... 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
