  1. 16. Aluminium alloy property data in engineering design

    Författare :Joacim Hagström; KTH; []
    Nyckelord :;

    Sammanfattning : The vast amount of materials existing today and the fastdevelopment of new and modified ones make it favourable to haveaccess to computerised materials property data. The advantagesare fast access and the possibility to process datainstantaneous. LÄS MER

  3. 17. The Role of Microstructure in the Atmospheric Corrosion of Selected Light Alloys and Composites

    Författare :Mohsen Esmaily; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; galvanic corrosion; Al content; microstructure; intermetallic particles; atmospheric corrosion; Al alloy 6xxx; casting; Mg-Al alloys; FSW P; BFSW.; Mg alloys-based MMCs;

    Sammanfattning : Magnesium-aluminum (Mg-Al) alloys, Mg-based metal matrix composites (MMCs) and Al alloys are among the best material candidates for future lightweight solutions. However, the use of these materials is limited by a number of issues, including the ability to resist corrosion. LÄS MER

  4. 18. Mechanical Properties of Welds at Creep Activation Temperatures

    Författare :Henrik C.M. Andersson-Östling; Rolf Sandström; Kamran Nikbin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; creep; creep crack propagation; OFHC copper; welds; nuclear waste disposal; creep modeling; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Welds in materials intended for service at temperatures above the creep activation temperature often develop damage before the base metal. The weld is a discontinuity in the material and stresses and strains often accumulate in the weld. Knowledge of the properties of the weld is essential to the safe operation of the component containing the weld. LÄS MER

  5. 19. 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
