  1. 1. Thermodynamic Modelling and Experimental Investigation of Tungsten Partitioning in Nickel Based Alloys

    University essay from KTH/Materialvetenskap

    Author : Joshva Kumpati; [2018]
    Keywords : Calphad; Tungsten partitioning; Nickel based alloys; Thermo-Calc; Thermodynamic database; Ni-W binary; Calphad; volframpartitionering; Nickelbaslegering; Termo-Calc; Termodynamisk databas; Ni-W;

    Abstract : Thermo-Calc software AB develops high quality thermodynamic and kinetic databases to predict and simulate accurately multi-component phase behaviour in complex systems. One problem with their Ni-based alloys and superalloy solutions database (TCNI8) is poor description of tungsten partitioning for multi-component nickel based alloys. READ MORE

  2. 2. Independent Project in Chemical Engineering and Materials Engineering : A literature study of powder-based additive manufacturing

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Daniel Feldt; Petra Hedberg; Asker Jarlöv; Elsa Persson; Mikael Svensson; Filippa Vennberg; Therese You; [2018]
    Keywords : Additive manufacturing; selective laser melting; electron beam melting; binder jetting; stainless steel; tool steel; nickel alloys;

    Abstract : The focus of this literary study was additive manufacturing (AM) and the purpose was to find general trends for selected materials that have been additively manufactured and compare them to results from other reviews. The raw materials studied were stainless steels 316L, 17-4 PH, 15-5 PH and 420, as well as tool steel H13 and nickel alloys 625, 718 and Hastelloy X. READ MORE

  4. 4. Effect of carbon activity on microstructure evolution in WC-Ni cemented carbides

    University essay from KTH/Materialvetenskap

    Author : Olivia Danielsson; [2018]
    Keywords : Cemented carbides; Hard metal; WC-Ni; Tungsten carbide; Nickel binder; Grain coarsening; Grain growth; Carbon activity; Size distribution; EBSD; Electron backscattered diffraction;

    Abstract : The aim of this work was to systematically study how the microstructure evolution is affected by the carbon activity in WC-Ni cemented carbides. Seven WC-9.59at%Ni alloys with different carbon activity were sintered at 1500 °C. READ MORE

  5. 5. Development of aluminium-silicon alloys with improved properties at elevated temperature

    University essay from Högskolan i Jönköping/JTH, Material och tillverkning

    Author : Toni Bogdanoff; [2017]
    Keywords : Al-Si alloy; Nickel; Cobalt; Elevated temperature properties; Microstructure;

    Abstract : Aluminium-silicon alloys have gained increasing market share in the automotive and aerospace industry because of increased environmental demands. These alloys have a high strength-to-weight ratio, good corrosion resistance, castability and recycling potential. READ MORE
