    Sammanfattning : With the advent of environmental issues in the public debate, historians world-wide have shown an increased interest in studying environmental issues. In this field of study, phenomena such as industrialisation, as well as economic and technological progress, have often been understood solely as the causes of environmental degradation with few attempts to examine the more complex features of the technology-environment relationship.

    Sammanfattning : Small and medium-sized enterprises badly need new knowledge. Their need is constantly increasing due to the market demand for custom-designed products, which means companies must be more flexible. Wood processing companies are having difficulty establishing contact with academia in order to meet this need. LÄS MER

  7. 5. Processability of Laser Powder Bed Fusion of Alloy 247LC-Influence of process parameters on microstructure and defects

    Författare :Olutayo Adegoke; Joel Andersson; Robert Pederson; Moataz Attallah; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser powder bed fusion; Alloy 247LC; additive manufacturing; nickel-based superalloys; processability; cracks; voids; Laserpulverbäddssmältning; legering 247LC; additiv tillverkning; superlegeringar; processbarhet; sprickor; porositet.; Production Technology; Produktionsteknik;

    Sammanfattning : This thesis is about laser powder bed fusion (L-PBF) of the nickel-basedsuperalloy Alloy 247LC. Alloy 247LC is mainly used in gas turbine blades and processing the blades with L-PBF may confer performance advantage over the blades manufactured with conventional methods. LÄS MER
