  1. 16. Aspects of Heat Flow in Laser Processing of Metals

    Författare :Jesper Sundqvist; Alexander F.H. Kaplan; John Powell; Andreas Otto; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : Since the laser was invented in 1960, its use in manufacturing industry has been growing rapidly. Laser processing of metals is based on the flow of heat that is generated by the absorbed laser beam. LÄS MER

  2. 17. Modelling microstructure evolution of weld deposited Ti-6Al-4V

    Författare :Corinne Charles; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal deposition; Ti-6Al-4V; microstructure modelling; titanium alloy; Finite Element Method; Johnson-Mehl-Avrami; RTMwD; Materials science; Teknisk materialvetenskap; Manufacturing and materials engineering; Produktions- och materialteknik; Material Mechanics;

    Sammanfattning : The microstructure and consequently the mechanical properties of titanium alloys are highly dependent on the temperature history endured by the material. The manufacturing process of metal deposition induces repetitive cooling and heating in the material determining a specific microstructure. LÄS MER

  3. 18. Laser welding of ultra-high strength steel and a cast magnesium alloy for light-weight design

    Författare :Karl Fahlström; Lars-Erik Svensson; Leif Karlsson; Michael Rethmeier; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; ultra-high strength steel; cast magnesium alloy; light-weight design; automotive industry; distortion; porosity; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : There is a strong industrial need for developing robust and flexible manufacturing methods for future light-weight design. Better performing, environmental friendly vehicles will gain competitive strength from using light weight structures. LÄS MER

  4. 19. Magnetic Fields and Induced Power in the Induction Heating of Aluminium Billets

    Författare :Mark William Kennedy; Ragnhild E. Aune; Andreas Westermoen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction; heating; billets; coils; magnetic fields;

    Sammanfattning : Induction heating is a common industrial process used for the reheating of billets before extrusion or forging. In this work the influence of the coil and work piece geometry, the effect of the electrical properties of the work piece, and the coil current and frequency, on the magnetic flux density and resulting work piece heating rates were studied.

  5. 20. Means to Optimize the Nutritional Properties of Starch in Potato Products - Impact on glycaemia, satiety and resistant starch content

    Författare :Margareta Leeman; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Näringslära; amylopectin; starch; glycaemic index; resistant starch; Nutrition; vinegar; satiety; amylose; Solanum tuberosum; potato;

    Sammanfattning : Despite decreased consumption potatoes still constitute an important staple in the Swedish diet. An objection to potatoes and potato products from a nutritional point of view is the ease by which the starch is digested and absorbed in the gastrointestinal tract. LÄS MER
