  2. 11. Microstructural development in laser-based powder bed fusion - from ferritic stainless steel to medium entropy alloys

    Author : Sri Bala Aditya Malladi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; interstitial solid solution strengthening; ferritic stainless steels; inoculation; Laser-based powder bed fusion; microstructural characterization; medium entropy alloys;

    Abstract : Ever since the advent of additive manufacturing (AM), the interest in AM technologies has skyrocketed due to its intrinsic ability to produce near net shaped components. Laser-based powder bed fusion (LB-PBF), being one of the most widely adapted AM technologies, has been especially a game changer due to its ability to produce components of complex geometries with improved designs and to reduce not only the final weight of the products but also the amount of the waste produced.

    Abstract : The automotive industry is moving from mass production towards an individualized production, in order to improve product quality and reduce costs and material waste. This thesis concerns aspects of load balancing of industrial robots in the automotive manufacturing industry, considering efficient algorithms required by an individualized production. READ MORE

  5. 13. 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

  6. 14. Brownfield Factory Layout Planning using Realistic Virtual Models

    Author : Daniel Nåfors; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision support; factory layout planning; manufacturing systems; Industry 4.0; Production systems; digitalisation;

    Abstract : To stay competitive in an increasingly digitalised and global context, manufacturing companies need to increase productivity and decrease waste. This means their production systems must improve; something they can achieve in a multitude of ways. READ MORE

  7. 15. System studies of the use of industrial excess heat

    Author : Sarah Broberg Viklund; Magnus Karlsson; Mats Söderström; Semida Silveira; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; waste heat; surplus heat; energy systems; greenhouse gas emissions; energy efficiency; energy policy; system studies;

    Abstract : Energy, materials, and by-products, can be exchanged between companies, having positive effects in the form of improved resource efficiency, environmental benefits, and economic gains. One such energy stream that can be exchanged is excess heat, that is, heat generated as a by-product during, for example, industrial production. READ MORE
