    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam; Powder bed fusion; EBM; PBF-EB; PBF-EB M; PBF-EB C; Process development; Material development; Ti-6Al-4V; 316L; V4E; Al2O3;

    Sammanfattning : Electron beam powder bed fusion (PBF-EB) is an additivemanufacturing (AM) method based on layer-by-layer melting of apowder bed. The technology is industrialized in certain applicationsbut still considered as immature and is not as widely used as laserbeam-based systems (PBF-LB). LÄS MER

  5. 9. Constitutive and fatigue crack propagation behaviour of Inconel 718

    Författare :David Gustafsson; Kjell Simonsson; Johan Moverare; Sjöström Sören; Sten Johansson; Christer Persson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nickel-base superalloys constitutive modelling mean stress relaxation fatigue crack propagation hold times grain boundary embrittlement;

    Sammanfattning : In this licentiate thesis the work done in the TURBO POWER project Influence of high temperature hold times on the fatigue life of nickel-based superalloys will be presented. The overall objective of this project is to develop and evaluate tools for designing against fatigue in gas turbine applications, with special focus on the nickel-based superalloy Inconel 718.
