    Abstract : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.

  4. 2. Heterogeneous deformation of multi-phase engineering materials - an in-situ neutron diffraction study

    Author : Nitesh Raj Jaladurgam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eutectic high entropy alloys; in-situ neutron diffraction; Deformation mechanisms; Superalloys; Electron microscopy;

    Abstract : Gas turbines are complex power generation systems used in aerospace or land-based-power stations. Materials such as Ni-base superalloys are involved in the combustion zone of these machines, which continuously experiences harsh environments with loading at high temperatures. READ MORE

  5. 3. Fibre-reinforced Concrete for Industrial Construction - a fracture mechanics approach to material testing and structural analysis

    Author : Ingemar Lövgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ cast; non-linear; self-compacting; fibre-reinforced; concrete;

    Abstract : ABSTRACTMore efficient and industrialised construction methods are both necessary for thecompetitiveness of in-situ concrete and essential if the construction industry is to moveforward. At present, the expenditure on labour (preparation and dismantling offormwork, reinforcing, and casting and finishing of concrete) almost equals the cost ofmaterial. READ MORE

  6. 4. In-situ concrete frameworks in multifamily buildings : Modelling and simulation of construction methods and activities

    Author : Robert Larsson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In Sweden and elsewhere in the world the construction industry has encountered criticism due to its lower productivity gains in comparison to other industries. This is why continual improvement of processes and forms of cooperation are important, as is utilisation of technologies giving greater efficiencies. READ MORE

  7. 5. High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties

    Author : Markus Peterson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-storey residential buildings; Structural frames; SCC; Self-compacting concrete; High-performanceconcrete; HPC; Concrete; Building materials; Cast in-situ concrete;

    Abstract : Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. READ MORE
