Evaluation of structure and magnetic properties of maraging steel powder feedstock for additive manufacturing of magnetic components

Clean production and utilisation of hydrogen in molten salts

“…The low cost and green fabrication of metallic powders using this innovative approach should be interesting, particularly considering the rise of additive manufacturing that utilises metallic powders for the precise, fast and economical manufacturing of components for various industries including aerospace, automotive, energy, and biomedical applications. [100][101][102] It is worth mentioning that in the traditional hydrogen reduction processes, metal oxides are reduced by a hydrogen gas stream, from which only a small fraction of hydrogen molecules can contribute to the reduction process 41,42 and the rest ows away from the reduction zone. In contrast, in the molten salt process, hydrogen is gradually formed in the vicinity of metal oxides, and therefore, a substantially less amounts of hydrogen is required, contributing to the high efficiency of the process.…”

Effect of post-treatment on local mechanical properties of additively manufactured impellers made of maraging steel

“…Additive manufacturing (AM) is an innovative and rapidly developing technology, in which the material is deposited layerby-layer, based on the three-dimensional computer-aided design model without a necessity of prior process planning. The main benefits of AM are creation of customized parts of complex shapes including lightweight design, minimal overall material waste of small-batch manufacturing and unique possibility of part reparation or redesign (Bajaj et al, 2020; The current issue and full text archive of this journal is available on Emerald Insight at: https://www.emerald.com/insight/1355-2546.htm Gotterbarm et al, 2020;Thotakura et al, 2020;Melzer et al, 2021;Pragana et al, 2021). The interest in AM continues to grow, attracting the attention of many researchers.…”
