  2. 1. Optimization product parts in high pressure die casting process

    Author : Mohammad Sadeghi; Rebei Bel-fdhila; Dan Loyd; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industriell ekonomi och organisation; Industrial Economics and Organisations;

    Abstract : This thesis describes optimization of die temperature in high pressure die-casting (HPDC) of A380 alloy by experimental observation and numerical simulation with the use of statistical tools. The goal of this research is to determine the optimum die temperature to minimize incidence of these defects and thus maximize production of parts without defects. READ MORE

  4. 2. Thermal cracking of young concrete : partial coefficients, restraint effects and influence of casting joints

    Author : Martin Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Cracks can occur due to temperature induced movements during the hardening phase of concrete. Thermal cracks are not decisive for the load-bearing capacity but cause costs for repair and may reduce the life of the structure. The risk of cracking can be judged through safety values, (partial coefficients) given in building codes. READ MORE

  5. 3. Gene : on the origin, function and development of sedentary Iron Age settlement in northern Sweden

    Author : Per H. Ramqvist; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; sedentary; settlement; colonization; internal development; origin; development; three-aisled long-houses; house construction; room division; inter-regional structure; iron forging; bronze casting; Järnåldern;

    Abstract : This thesis deals with questions concerning the sedentary settlement in central Norrland: its origins, function and development. This type of settlement appears at the start of our calendar. The material comprises an almost fully excavated farmstead from the Early Iron Age (1-600 A.D. READ MORE

  6. 4. Densities and viscosities of slags : modeling and experimental investigations

    Author : Mikael Persson; Seshadri Seetharaman; Rob Brooks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; density; nolar volume; thermodynamics; enthalpies; model; slags; oxide melts; viscosity; mould flux; continuous casting; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : The present dissertation describes part of the efforts directed towards the development of computational tools to support process modeling. This work is also a further development of the Thermoslag software developed in the Division of Materials Process Science, KTH. READ MORE

  7. 5. Rheocasting of Aluminium Alloys : Slurry Formation, Microstructure, and Properties

    Author : Mostafa Payandeh; A. E. W. Jarfors; Torbjörn Carlberg; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SSM Casting; aluminium alloy; RheoMetalTM process; microstructure; physical and mechanical properties;

    Abstract : Innovative materials with novel properties are in great demand for use in the criticalcomponents of emerging technologies, which promise to be more cost-effective and energyefficient.A controversial issue with regard to manufacturing complex industrial products isto develop advanced materials with optimised manufacturability in addition to the requiredmechanical and physical properties.
