  1. 16. Accelerate ageing of refuse-derived-fuel (RDF) fly ashes

    Författare :Evelina Brännvall; Britt-Marie Steenari; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : Ashes have properties that can be exploited in various applications, e.g. some ashes can be used in the construction of barriers in a landfill final top cover. LÄS MER

  3. 17. Characterization of Raw Materials for Salt Extraction from Lake Katwe, Uganda

    Författare :Hillary Kasedde; Stefan Jonsson; Baohua Zhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; characterization; PHREEQC;

    Sammanfattning : Uganda is well endowed with economic quantities of salt evident in the interstitial brines and evaporite deposits of Lake Katwe, a closed saline lake located in the western branch of the great East African rift valley. Currently, rudimentally methods of salt mining based on solar evaporation of brine continue to be used for salt extraction at the lake. LÄS MER

  4. 18. High strain rate deformation of Alloy 718

    Författare :Joakim Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Split-Hopkinson; Alloy 718; Johnson-Cook;

    Sammanfattning : Alloy 718 is a high temperature alloy, used where high temperature strength or oxidation resistance is required. As the alloy is precipitate heat treatable it is possible to have a large variety of strength depending on microstructure. LÄS MER

  5. 19. Microstructure Evolution and Mechanical Properties of Haynes 282

    Författare :Ceena Joseph; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma prime; carbide stabilization treatment; heat treatment; Haynes 282; isothermal transformation; anisotropy ductility; solution treatment; carbides; microstructure;

    Sammanfattning : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. LÄS MER

  7. 20. An Experimental Study of a Liquid Steel Sampling Process

    Författare :Ola Ericsson; Andrey Karasev; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; inclusion characteristics; sampling conditions; sample homogeneity.; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : During the steelmaking process samples are taken from the liquid steel, mainly to assess the chemical composition of the steel. Recently, methods for rapid determination of inclusion characteristics (size and composition) have progressed to the level where they can be implemented in process control. LÄS MER
