  3. 32. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction

    University essay from KTH/Materialvetenskap

    Author : Leyla Koort; Viktoria Sutorius Trollbäck; [2021]
    Keywords : ;

    Abstract : The formation of non-metallic inclusions (NMIs) are common in all steel grades and it is not possible  as  of  today  to  be able  to  remove  all  of them.  The  inclusions  are  categorised  into endogenous (oxides, nitrides, sulfides, carbides, and phosphides), and exogenous (entrapment of  nonmetals:  slag, mold).

  4. 33. Improvement and Development of Powder Spreadability Testing

    University essay from KTH/Materialvetenskap

    Author : Fabrice Rosala; [2021]
    Keywords : ;

    Abstract : With rising interest in metal additive manufacturing and, specifically, in powder bed fusion processes, it is essential to understand relevant process parameters and the behavior of powders used in such processes. At the time of writing, the flow behavior of powders is in the spotlight whereas little research into the spreadability of a powder is being conducted. READ MORE

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

    University essay from Karlstads universitet

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

    Abstract : 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. READ MORE
