  4. 23. Parameter study of a muffle furnace performance on powder heating using numerical multiphysics simulation with COMSOL

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Emil Stålnacke; [2015]
    Nyckelord :muffle furnace; syngas; biomass; natural gas; parameter study; comsol; powder metallurgy; heat transfer;

    Sammanfattning : The muffle furnace main purpose is to anneal the rough sponge iron powder transported through it, which is done by burning natural gas. Heat is absorbed by the muffle and is transferred to the bed of sponge iron powder. LÄS MER

  5. 24. A model-based design approach to redesign a crankshaft for powder metal manufacturing

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Vasileios Angelopoulos; [2015]
    Nyckelord :Crankshaft; balancing; modularization; Powder Metallurgy; Vevaxel; balansering; modularisering; pulvermetallurgi;

    Sammanfattning : A crankshaft is a component which is used to convert a reciprocating movement into rotating or vice versa. Through the past years classical manufacturing techniques did not leave space for a new approach regarding manufacturing this component. LÄS MER

  7. 25. CALPHAD study of cubic carbide systems with Cr

    Master-uppsats, KTH/Materialvetenskap

    Författare :Zhangting He; [2015]
    Nyckelord :CALPHAD; cubic carbide; thermodynamics;

    Sammanfattning : Cubic carbides (titanium, tantalum, niobium, and zirconium carbides) can constitute a significant proportion of so-called cubic and cermet grades, where it is added to substitute a portion of tungsten carbide. It is thus critical to understand and be able to thermodynamically model the cubic carbide systems. LÄS MER
