  2. 1. Process Development for Electron Beam Melting of 316LN Stainless Steel

    Author : Stefan Roos; Lars-Erik Rännar; Andrei Koptioug; Jonas Danvind; Lars Pejryd; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; beam deflection rate; electron beam melting; energy input; material properties; microstructure; powder bed fusion; process parameters; 316LN stainless steel;

    Abstract : Additive manufacturing (AM) is a technology that inverts the procedure of traditional machining. Instead of starting with a billet of material and removing unwanted parts, the AM manufacturing process starts with an empty workspace and proceeds to fill this workspace with material where it is desired, often in a layer-by-layer fashion.

  4. 2. Hole deviations in percussion drilling and control measures : theoretical and field studies

    Author : Thomson Sinkala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : In this thesis, we study the problem of hole deviations in percussive drilling and present a solution to minimize the deviations. Field tests are performed to study the interactive behaviour of drilling parameters. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vancomycin; electrochemistry; transducer; DUV lithography; nanoimprint lithography; thin film; cantilever; sensor; interdigitated electrode; electrostatic interaction; mix-and-match processing; bacteria; Fysicumarkivet A:2010:Skjolding;

    Abstract : This thesis focuses on the study of thin-film sensor technologies, novel microfabrication technologies, and thin-film technology in general. The work discusses electrochemical sensors and mechanical sensor technologies as well as fabrication strategies for them. READ MORE

  6. 4. Laser-driven particle acceleration - Experimental investigations

    Author : Filip Lindau; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis describes experimental studies of laser-driven particle acceleration. With the focused intensity of today’s high-power lasers exceeding 10^18 W/cm2,extremely high-gradient accelerators are possible. READ MORE
