  1. 1. The effect of printing parameters on the deformation and microstructure of Inconel 718 : A study in pulsed laser and powder based directed energy deposition additive manufacturing

    Master-uppsats, KTH/Materialvetenskap

    Författare :Elias Repper; [2020]
    Nyckelord :Laser; Additive Manufacturing; Metal; Deposition; Quasi-continuous-wave; Pulsed; Ni-base superalloy; Laves; Deformation; Residual stresses;

    Sammanfattning : Additive manufacturing has the power to redefine how we create components. In order to minimize removal of printed material, deformation must be kept a minimum. When deposition rate is increased during directed energy deposition so is the power requirement for melting the feedstock. LÄS MER

  3. 2. Unga vuxnas delaktighet i församlingsgemenskapen : En självklarhet eller en anpassning till rådande strukturer?

    Kandidat-uppsats, Enskilda Högskolan Stockholm/Avdelningen för religionsvetenskap och teologi

    Författare :Johanna Karlsson; [2018]
    Nyckelord :;

    Sammanfattning : Denna studie syftar till att undersöka hur församlingsaktiva unga vuxna, med olika etnisk och religiös bakgrund, upplever delaktighet i några församlingar inom Equmeniakyrkan. Med unga vuxna avses informanter i åldern 16 till 26 år. Undersökningen bygger på tre semistrukturerade fokusgruppssamtal med sammanlagt sexton informanter. LÄS MER

  4. 3. Study of the effect of process parameters in laser blown powder with superalloys : Varying laser power and scanning speed, analyzing material properties

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Viktor Pettersson; [2018]
    Nyckelord :Additive manufacturing; Laser Blown Powder; Haynes 282; Inconel 718;

    Sammanfattning : Additive manufacturing (AM) is a growing process interesting many companies in many industries. Thereare multiple processes within the familty of AM, but this study focuses on laser blown powder (LBP). LBP involves a laser beam focused on the substrate with powder being blown into the laser beam. LÄS MER

  5. 4. Characterization of Laser Deposited Alloy 718

    Master-uppsats, KTH/Materialvetenskap

    Författare :Pengcheng Cao; [2016]
    Nyckelord :Additive; Deposition; Alloy 718;

    Sammanfattning : Additive Manufacturing (AM) is a method of producing three-dimensional objects using additive processes. It allows great flexibility in the processes and reduces the design-to-production time. Laser Metal Deposition (LMD) is one of AM methods under development and is based on the deposition technology.

  7. 5. Homogenization of Precipitation Hardening Nickel Based Superalloys

    Master-uppsats, Materialvetenskap

    Författare :Olutayo Adegoke; [2012]
    Nyckelord :;

    Sammanfattning : Allvac 718 Plus and Haynes 282 are relatively new precipitation hardening nickel based superalloys with good high temperature mechanical properties. In addition, the weldability of these superalloys enhances easy fabrication. LÄS MER
