    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ti-6Al-4V; Electron beam melting; Microstructures; Surface roughness; phase filed modelling.;

    Abstract : The work presented in this dissertation is concerned with the microstructures and surface roughness of test slabs of Ti-6Al-4V produced by one of powder based Additive Manufacturing (AM) technique namely electron beam melting (EBM). The effects of process parameters of a EBM system and geometry factors of a EBM build such as slabs’ thickness and height etc. READ MORE

  5. 3. Defects in E-PBF Ti-6Al-4V and their Effect on Fatigue Behaviour : Characteristics, Distribution and Impact on Life

    Author : Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Hans Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Materialteknik; Engineering Materials;

    Abstract : Layer by layer manufacturing (additive manufacturing, AM) of metals is emerging as an alternative to conventional subtractive manufacturing with the goal of enabling near net-shape production of complex part geometries with reduced material waste and shorter lead times. Recently this field has experienced rapid growth through industrial adaptation but has simultaneously encountered challenges. READ MORE

    Abstract : Titanium alloys are widely used for components in the fan and compressor sections of aeroengines mainly because of their superior strength-to-weight ratio. Large static compressor components can be manufactured by welding together smaller subcomponents, which has potential to provide benefits such as higher buy-to-fly ratio and improved performance of the components.
