  4. 2. Microstructure and Texture of Additive Manufactured Ti-6Al-4V

    Author : Magnus Neikter; Marta-Lena Antti; Johan Moverare; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; microstructure; Ti-6Al-4V; texture; Material Mechanics; Materialmekanik;

    Abstract : Additive manufacturing (AM) for metals is a manufacturing process that has increased a lot in popularity last few years as it has experienced significant improvements since its beginning, both when it comes to accuracy and deposition rates. There are many different AM processes where the energy sources and deposition methods varies. READ MORE

  5. 3. Effect of Stress Relief Annealing: Part Distortion, Mechanical Properties, and Microstructure of Additively Manufactured Austenitic Stainless Steel

    Author : Emil Edin; Marta-Lena Antti; Pia Åkerfeldt; Fredrik Svahn; Magnus Neikter; Paul Åkerström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser powder bed fusion; stainless steel; residual stress; heat treatment; tensile testing; relaxation testing; Materialteknik; Engineering Materials;

    Abstract : Additive manufacturing (AM) processes may introduce large residual stresses in the as-built part, in particular the laser powder bed fusion process (L-PBF). The residual stress state is an inherent consequence of the heterogeneous heating and subsequent cooling during the process. READ MORE

  6. 4. Investigating the effect of extending powder particle size distribution of Ti-6Al-4V produced by powder bed fusion laser beam process : Influence of process parameters on material integrity

    Author : Linda Squillaci; Magnus Neikter; Ru Peng; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powder Bed Fusion Laser Beam PBF-LB ; Ti-6Al-4V; Microstructure; Particle Size Distribution PSD ; Productivity Enhancement; Pulverbädd additiv tillverkning PBF-LB M ; Ti-6Al-4V; Mikrostruktur; Pulverpartikelstorleksfördelning; Produktivitetsförbättring; Production Technology; Produktionsteknik;

    Abstract : This thesis focuses on the topic of PBF-LB applied to titanium alloys. Of allalloys, an α + β is chosen, named Ti-6Al-4V. The selection of this particular alloy is driven by its current widespread use in many industrial applications where high strength coupled with low density are both desirable properties. READ MORE
