16. Microstructure and properties of welds in the lean duplex stainless steel LDX 2101
Sammanfattning : Duplex stainless steels can be very attractive alternatives to austenitic grades due to their almost double strength at equal pitting corrosion resistance. When welding, the duplex alloys normally require addition of filler metal, while the commodity austenitic grades can often be welded autogenously. LÄS MER
17. Experimental study and simulation of sintering of 316L components produced by binder jetting
Sammanfattning : Binder Jetting (BJT) is a multi-step Additive Manufacturing (AM) technique that is used for producing components with highly complex geometries and competitive final properties with high productivity when compared to other AM technologies. The first step provides the basic part geometric shape (BJT printing), and the next step (debinding and sintering) consolidates the part to reach final geometry and intended basic material properties.

18. Increased Productivity of Ferrous Alloys Produced by Powder Bed Fusion - Laser Beam
Sammanfattning : Low production speeds limit wider adoption of powder bed fusion – laser beam (PBF-LB) in cost sensitive industries as it correlates directly with high production costs. The main process parameters such as scan speed, hatch distance and layer thickness can be scaled up to increase build speed, but it often comes at a trade off in lower quality, i. LÄS MER
19. Laser-based powder bed fusion of stainless steels
Sammanfattning : The aim of the present work has been to widen the knowledge of how variations within powder manufacturing affect laser-based powder bed fusion processing, and how this processing affects the microstructure and strength of stainless steels. The approach was to keep the processing parameters fixed while the powder feedstock was varied. LÄS MER
20. Evaluations of Non-metallic Inclusionsin Ca-treated Steels and Their Effect on the Machinability
Sammanfattning : In recent decades, a considerable development of steel with respect to the performance of steel has taken place, which also has resulted in large challenges to process these steel grades. Therefore, it is essential to make suitable modifications of non-metallic inclusions (NMI) in the steelmaking process and to have a good control of its characteristics to meet the target mechanical properties and to obtain a good machinability.
