1. Powder Bed Fusion – Laser Beam of Mg alloy WE43 : Establishing the process – structure – properties relationship
Sammanfattning : Powder bed fusion - laser beam (PBF-LB) of Mg alloy WE43 (Mg-4wt%Y-3wt%RE-Zr) has great potential for the development of future biodegradable metal implants, as well as aerospace lightweight materials. However, the work published thus far has mainly focused on obtaining a fully dense material, and the understanding of the relationship among the PBF-LB process parameters, structure and the resulting material properties remains limited.

2. Powder degradation during powder bed fusion processing: impact of processing conditions and alloy composition
Sammanfattning : In the recent decade, powder bed fusion (PBF) metal additive manufacturing (AM) has attracted huge attention both from the industry and the research community. This effort has helped mature PBF technology as a potential alternative to conventional manufacturing processes as casting, machining, forging, etc. LÄS MER
3. Development of Structural Steels for Powder Bed Fusion - Laser Beam
Sammanfattning : Over the past decade, powder bed fusion – laser beam (PBF-LB) has attracted noticeable attention from both academia and industry. However, there remains a scarcity of approved material for the process, as fewer than 40 alloys are commercially available. LÄS MER
4. Investigating the effect of extending powder particle size distribution of Ti-6Al-4V produced by powder bed fusion laser beam process : Influence of process parameters on material integrity
Sammanfattning : This thesis focuses on the topic of PBF-LB applied to titanium alloys. Of allalloys, an α + β is chosen, named Ti-6Al-4V. The selection of this particular alloy is driven by its current widespread use in many industrial applications where high strength coupled with low density are both desirable properties. LÄS MER
5. 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
