Research ArticleOpen accessIn the abstractHardening Effects of In-Situ Aging for a Laser Welded Maraging SteelMilton Sergio Fernandes de Lima, Rafael Humberto de Mota Siqueira, Sheila Medeiros de Carvalho, Antonio Jorge AbdallaMaraging steels are ultra-high strength alloys which have been successfully laser welded to obtain structural components. For most of the applications these steels are in an aged state to attain tensile strength up to 1.5 GPa, although welding induces local softening due to dissolution of precipitates. This paper aims to investigate the effect of in-situ aging of the maraging steel … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 12 Nov 2019 · 7,210 accessesView PDFCite
