  2. 1. High Temperature Corrosion Behaviour of Ni-base Alloys and FeCrAl Alloys – The Influence of Water Vapour

    Author : Tommy Sand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr-evaporation; FeCrAl alloy; Oxidation; Chromia scale; Alumina scale; High-temperature corrosion; Ni-base alloy;

    Abstract : Electricity production, transportation, and manufacturing industry are some of the largest sources of greenhouse gas emissions. In many cases, these processes are carried out at high temperature and energy efficiency is limited by material degradation, so-called ‘high-temperature corrosion’. READ MORE

  4. 2. High-temperature corrosion properties of chromia- and alumina-forming alloys

    Author : Tommy Sand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-temperature corrosion; Alumina scale; Chromia scale; Cr-evaporation; Nitridation; Oxidation;

    Abstract : Electricity production, transportation, and manufacturing industry are some of the largest sources of greenhouse gas emissions. In many cases, these processes are carried out at high temperature and energy efficiency is limited by material degradation, so-called ‘high-temperature corrosion’. READ MORE

  5. 3. Sampling from large flotation cells : An invastigation of spatial distribution

    Author : Lisa Malm; Jan Rosenkranz; Tommy Karlkvist; Anders Sand; Nils-Johan Bolin; Pertti Lamberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flotation; sampling; Mineral Processing; Mineralteknik;

    Abstract : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. READ MORE

  6. 4. Large-scale testing of granular material

    Author : Elin Bergliv; Jan Laue; Tommy Edeskär; Stefan Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : The main problem to investigate in this study is if larger grained materials, up to 200 mm nominal size, could be used as an embankment material for high-speed railways. High-speed railways have very strict settlement requirements, allowing only very small settlements to ensure safety. READ MORE
