    University dissertation from Stockholm : Materialvetenskap

    Author : Akira Yamauchi; KTH.; [2001]
    Keywords : Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

    Abstract : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. READ MORE

  2. 2. Mechanical properties and microstructure of laser sintered and starch consolidated iron-based powders

    University dissertation from Karlstad : Karlstads universitet

    Author : Yu Wang; Karlstads universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Materialteknik; Materials Engineering; Powder metallurgy; Laser sintering; Microstructure; Fatigue; Thermal fatigue; Wear; Starch consolidation; Rapid forming; Net shaping; Liquid phase sintering; Nitriding; High speed steels;

    Abstract : In powder metallurgy research field, Direct Metal Laser Sintering (DMLS) and Metal Powder Starch Consolidation (MPSC) are relatively new rapid forming techniques to fabricate complex and near net-shaped components. The working principles of DMLS are to melt and fuse metal powder layer by layer in computer controlled systems to pile up components like three dimensional printing. READ MORE

  3. 3. Optimization product parts in high pressure die casting process

    University dissertation from Västerås : Mälardalen University

    Author : Mohammad Sadeghi; Mälardalens högskola.; [2015]
    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
