  2. 1. Investigations on the Formation of Defect Bands in Semi-Solid High Pressure Die Cast Aluminium-Silicon Alloys

    Author : Madeleine Law; Pär Jönsson; Christopher Hulme-Smith; Taishi Matsushita; Jessica Elfsberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Semi-Solid Metals; SSM; Al-Si Alloys; Defect bands; HPDC; Semisolida metaller; SSM; Al-Si-Alloys; defektband; HPDC; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : High-pressure die casting of semi-solid aluminium-silicon alloys is used in the automotive industry to manufacture components, like housings, brackets, and bars. It is commonly known that during high-pressure die casting, defect bands may be created that follow the contour of the component surface. These bands consist mainly of a eutectic phase. READ MORE

  4. 2. Sea Ice and Ocean Environmental Applications of Spaceborn SAR

  7. 5. Sensitivity and Uncertainty Analysis of Boiling Water Reactor Stability Simulations

    Author : Ivan Gajev; Weimin Ma; Tomasz Kozlowski; Kostadin Ivanov; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; SRA - Energy; SRA - Energi;

    Abstract : The best estimate codes are used for licensing of Nuclear Power Plants (NPP), but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. READ MORE
