  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

    University essay from KTH/Materialvetenskap

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

    Abstract : 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. READ MORE

  3. 2. Defect formation in laser welded steels after use of corrosion protection coating

    University essay from KTH/Materialvetenskap

    Author : Elias Repper; Amanda Carsbring; [2017]
    Keywords : Laser welding; steel; porosity; mid-section bulging; defects; corrosion protection;

    Abstract : This bachelor thesis was made in collaboration with Scania. The objective was to find the cause for defects found in some rear axle welds. It was known axle material was coated with anti-corrosive oil. Oils were examined through ICP-AES, and then compared to the composition found on the surface of the steel samples. READ MORE
