  1. 1. Fatigue Anisotropy in Forged Components

    Författare :Cornelius Temmel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inclusion Cluster; Low Sulfur; Machinability; Inclusion; Manganese Sulfide; Quenching Crack; Forging; Isotropic Quality; Steel; Anisotropy;

    Sammanfattning : Ever-growing requirements on combustion engine efficiency of motor vehicles demand increasing service loads in powertrain components. Optimization of component material is therefore inevitable. A major detriment with many forged transmission components is their anisotropic mechanical behavior, not least during cyclic loading.

  3. 2. Complex Phase Behavior in Thermoelectric Mg2Si1-xSnx Alloys and Development of Transient Plane Source Method for Structural Characterization

    Författare :Andrey Sizov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiphase structure; quality control; inhomogeneity tests; Rietveld refinement; Transient Plane Source method; isotropic and anisotropic materials; defects detection; advance measurements of thermal properties; X-ray diffraction; structural characterization; spark plasma sintering; magnesium silicide-stannide alloys; complex behavior; thermoelectric properties; thermal conductivity vs. probing depth;

    Sammanfattning : The thermoelectric effect was discovered nearly 200 years ago, but it started to be utilized for waste heat recovery only fairly recently. From an economical point of view, such applications requires a cheap and efficient material, which is able to convert heat energy into electricity. LÄS MER

  4. 3. Phase-Contrast and Spectroscopic X-ray Imaging for Paperboard Quality Assurance

    Författare :Salim Reza; Christer Fröjdh; Börje Norlin; Jan Thim; Anna Burvall; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The end-use performance of a paperboard depends on its quality.The major properties of a good quality paperboard include consistencyin the expected ratio between the thickness of the core andthe coating layers, and the uniformity in the coating layer. LÄS MER

  5. 4. Studies of the free mica properties and its influence on quality of road constructions

    Författare :Dimitri Kondelchuk; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Sammanfattning : The thesis presents series of laboratory studies of aggregates containing mica minerals obtained from aggregate producers located throughout Sweden. The main idea of the research was to study physical properties and behaviour of free mica particles in unbound granular products of crushed rock materials. LÄS MER

  7. 5. Evolution of coke properties while descending through a blast furnace

    Författare :Tobias Hilding; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Due to increasing price and economic pressures, there is a need to minimise coke consumption. The lesser amount of coke used has indirectly set higher standards for coke quality and led to a wish for even more knowledge about its function in the blast furnace. LÄS MER
