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

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, 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

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

    Sammanfattning : 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. LÄS MER

  4. 4. Korrosionsstudie om nickel-krom-molybden legeringar i våt skrubber.

    Kandidat-uppsats, Högskolan i Jönköping/JTH, Maskinteknik; Högskolan i Jönköping/JTH, Maskinteknik

    Författare :Simon Garza; Lundrim Shaqiri; [2016]
    Nyckelord :Ni-Cr-Mo alloys; wet scrubbers; corrosion; corrosion testing; Ni-Cr-Mo legeringar; våt skrubber; korrosion; korrosion test;

    Sammanfattning : Arbetet som utförts är en material studie som inriktar sig på nickel-krom-molybdenbaserade legeringar som används i dagens våt skrubber. Eftersom kraven på mängden utsläpp av svaveldioxid är en viktig miljöfråga, skapar detta ett behov för användandet av en våt skrubber. LÄS MER

  5. 5. Investigation Of Scalloping Effects Of Radial Turbines With Computational Fluid Dynamics

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Anders Jacobsson; [2016]
    Nyckelord :Radial turbine; scallop; inertia; turbocharger; STAR-CCM ; CFD; Technology and Engineering;

    Sammanfattning : Turbochargers should both have high efficiency and rapid engine response. By removing material from the rotating parts in the turbocharger, decreases the inertia. Most suited is the turbine in the turbocharger, which has high density because of nickel-based alloys. LÄS MER
