  1. 21. A model-based design approach to redesign a crankshaft for powder metal manufacturing

    University essay from KTH/Maskinkonstruktion (Inst.)

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

    Abstract : 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. READ MORE

  3. 22. CALPHAD study of cubic carbide systems with Cr

    University essay from KTH/Materialvetenskap

    Author : Zhangting He; [2015]
    Keywords : CALPHAD; cubic carbide; thermodynamics;

    Abstract : 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. READ MORE

  4. 23. Evaluation of Ce Addition by Different Wire inLiquid 316 Stainless Steel

    University essay from KTH/Materialvetenskap

    Author : Oscar Juneblad Målar; [2015]
    Keywords : Stainless steel; Continuous Casting; Mold Metallurgy; REM-­‐clusters; Electrolytic Extraction;

    Abstract : It is well known that REMs are strong oxide and sulphide formers that can easily form large clusters which have harmful effect on the casting process as well as the quality of the final steel product. By adding these elements right before casting, the number of narrow transfer parts are eliminated (compared to if added in ladle) Also, the REM inclusions has less time to sinter together to form large clusters, preventing clogging.

  5. 24. Characterization of Metal Powders Produced by Two Gas Atomizing Methods for Thermal Spraying Applications

    University essay from KTH/Materialvetenskap

    Author : Tim Pettersson; [2015]
    Keywords : Powder metallurgy; Gas atomization; Thermal Spraying; Ni-Si-B; Ni-boride;

    Abstract : This thesis work is focused on the influence of process parameters during gas atomization on the thermal spraying properties of a Ni-Cr-B-Si hardfacing alloy. The metal powder alloy, known as 1-60-20, is produced by Höganäs AB. READ MORE
