   Sammanfattning : Mg-RE based alloys have exhibited promising properties in application for biodegradable implants. This work provides a systematic study on the characterization of melt pool geometry and profile for one such alloy, WE43. LÄS MER

4. 18. Fabricability of a high alloy tool steel produced with LPBF, with a focus on part geometry

   Master-uppsats, Karlstads universitet

   Författare :Zulfaqar Abdelamir; [2021]
   Nyckelord :Addtive Manufacturing; Laser Powder Bed Fusion; High alloy Cold Work Tool Steel; Addtiv Tillverkning; LPBF; Höglegerat kallbearbetningsstål;

   Sammanfattning : Additive manufacturing (AM) is a promising manufacturing process that provides that ability to fabricate components with complex geometries with relatively low lead times compared to other manufacturing processes. This allows for more freedom of design, as prototypes can easily be produced throughout the development process. LÄS MER

5. 19. Fatigue properties of Laser Powder Bed Fusion (LPBF) built 21-6-9 stainless stee

   Master-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

   Författare :Jayanth Krishna; [2021]
   Nyckelord :stainless steels; LPBF; Fatigue; 21-6-9;

   Sammanfattning : Fatigue performance is one of the important mechanical properties which is hindering some of the additive manufacturing build structures. The main objective of this study is to investigate the fatigue life dependence of the 21-6-9 austenitic stainless-steel build using the laser powder bed fusion (LPBF) technique. LÄS MER
