1. 1. Process characterisation of an additive manufacturing equipment : An analysis of the effect of electron beam powder bed fusion process parameters on the melt pool geometry and microstructure of Ti-6Al-4V

   Master-uppsats, Linköpings universitet/Konstruktionsmaterial

   Författare :Ida Ljusell; [2023]
   Nyckelord :Additive manufacturing; AM; 3d printing; titanium; process characterisation; electron beam powder bed fusion;

   Sammanfattning : Additive manufacturing (AM) are manufacturing methods where components are produced by adding material layer by layer which allows for a high freedom of design as well as little or no material waste compared to conventional manufacturing methods. Despite the many benefits of AM there are still problems concerning the quality of the produced material. LÄS MER

   Sammanfattning : Microstructure and micro-mechanical characterization of as-built and heat-treated samples of Hastelloy X produced by laser powder bed fusion (LPBF) process has been carried out in this study. As-built LPBF blocks were solution heat-treated at 1177°C and 1220°C followed by fast cooling. LÄS MER

4. 3. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

   Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

   Författare :Jijesh Rajan; [2022]
   Nyckelord :Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

   Sammanfattning : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. LÄS MER
