16. Microstructure engineering of additively manufactured materials by powder bed fusion-laser beam: Cases for ferritic stainless steels and medium entropy alloys
Abstract : Powder bed fusion laser beam (PBF-LB) is a powder bed fusion additive manufacturing process that is one of the most established and widely used techniques for manufacturing near net shape components. The unique characteristics of PBF-LB, such as the high cooling rates and local directional heat transfer, lead to the formation of unique microstructures. READ MORE

17. Influence of microstructure on fatigue and ductility properties of tool steels
Abstract : Fatigue and ductility properties in various tool steels, produced by powder metallurgy, spray forming or conventionally ingot casting, have been analysed experimentally and successfully compared to developed models. The models are able to predict the fatigue limit and cause for fatigue fracture, and strain- and stress-development until fracture during the ductile fracture process respectively. READ MORE

18. Laser Based Powder Bed Fusion of Plain Carbon and Low-Alloy Steels: Microstructure and Processability
Abstract : Despite the prominence of laser based powder bed fusion (LB-PBF) as an additive manufacturing technique, the number of alloys that have been approved for the process remains limited. In traditional manufacturing, ferrous alloys are the most common alloy group, consisting primarily of plain carbon and low-alloy steels. READ MORE

19. Microstructural development in laser-based powder bed fusion - from ferritic stainless steel to medium entropy alloys
Abstract : Ever since the advent of additive manufacturing (AM), the interest in AM technologies has skyrocketed due to its intrinsic ability to produce near net shaped components. Laser-based powder bed fusion (LB-PBF), being one of the most widely adapted AM technologies, has been especially a game changer due to its ability to produce components of complex geometries with improved designs and to reduce not only the final weight of the products but also the amount of the waste produced.
