Determination of Anisotropic Mechanical Properties for Materials Processed by Laser Powder Bed Fusion
Hovig, Even Wilberg; S. Azar, Amin; Grytten, Frode; Sørby, Knut; Andreassen, Erik (Peer reviewed; Journal article, 2019)Improving the success rate in additive manufacturing and designing highly optimized structures require proper understanding of material behaviour. This study proposes a novel experimental method by which anisotropic ... -
A fully kinetic phase diagram-coupled multicomponent columnar-to-equiaxed grain transition model with an application to additive manufacturing
Du, Qiang; M'Hamdi, Mohammed; Reiersen, Magnus; Hovig, Even Wilberg; Zhang, Kai (Peer reviewed; Journal article, 2024)The columnar-to-equiaxed transition (CET) is known to impact crack formation during the additive manufacturing of metallic alloys. While previous experiments have shown that CET is tunable via its alloying elements, a ... -
High cycle fatigue life estimation of AlSi10Mg processed by laser powder bed fusion
Hovig, Even Wilberg; S. Azar, Amin; Sunding, Martin Fleissner; Sørby, Knut; M'hamdi, Mohammed; Andreassen, Erik (Journal article, 2018)Fatigue life is known to be dependent on the surface properties of the material. Surface roughness provokes local stress concentration and cause crack initiation even at minute cyclic loads. In laser powder bed fusion, ... -
An investigation of the anisotropic properties of heat-treated maraging steel grade 300 processed by laser powder bed fusion
Hovig, Even Wilberg; S. Azar, Amin; Solberg, Klas; Sørby, Knut (Peer reviewed; Journal article, 2021)In order to explore the possibilities enabled by laser beam powder bed fusion of metals (PBF-LB/M), reliable material models are necessary to optimize designs with respect to weight and stiffness. Due to the unique processing ... -
Laser beam remelting of stainless steel plate for cladding and comparison with conventional CMT process
Bunaziv, Ivan; Ren, Xiaobo; Hagen, Anette Brocks; Hovig, Even Wilberg; Jevremovic, Ivana; Gulbrandsen-Dahl, Sverre (Peer reviewed; Journal article, 2023)Progressing towards circular economy requires smarter and more efficient use of energy and resources. Laser beam can be efficient and flexible tool for melting different metals, commonly used in cladding and additive ... -
Mechanical Properties of AlSi10Mg Processed by Laser Powder Bed Fusion at Elevated Temperature
Hovig, Even Wilberg; S. Azar, Amin; M'hamdi, Mohammed; Sørby, Knut (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2020)AlSi10Mg processed by laser powder bed fusion is expected to have remarkable mechanical properties due to the dominant cellular microstructure. However, the as-processed material is often both anisotropic and containing ... -
Toward semantic standard and process ontology for Additive manufacturing
Gouttebroze, Sylvain; Friis, Jesper; Hovig, Even Wilberg; Boivie, Klas Magnus (Peer reviewed; Journal article, 2023)Advanced modelling of additive manufacturing often requires the combination of models at multiple scales and multi-physics. Therefore, building the modelling workflow describing the process is complicated. The modelling ...
