  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

  3. 2. The impact of stumps’ height on secondary spread of Heterobasidion parviporum in precommercial thinning stands of Norway spruce (Picea abies)

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Iwona Urban; [2015]
    Keywords : Norway spruce; Heterobasidion parviporum; precommercial thinning; wysokość pnia; świerk pospolity; czyszczenia późne;

    Abstract : The economic losses caused by Heterobasidion spp. infection is an important issue in the Swedish forestry sector where Scots pine and Norway spruce make up to 80% of the standing volume. Both of the fungi species naturally existing in Sweden: H. annosum and H. READ MORE

  4. 3. Heat Resistant Steel Alloys : Atlas Copco

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Malin From; Johanna Ejerhed; Artin Fattah; Markus Lindén; Alex Karlstens; [2015]
    Keywords : steel alloy heat resistant nitration;

    Abstract : Atlas Copco is interested in investigating the friction in the top-hammer drilling tool threads thatcauses the steel to heat up, leading to a phase transformation and a softer steel in the threads. Theaim of this project is to find a steel alloy or surface finishing that will retain its hardness atelevated temperatures better than the presently used threads material. READ MORE
