  1. 1. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  3. 2. Simulation of solidification and cooling of a casting product using COMSOL Multiphysics

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Tom Allen; [2019]
    Keywords : Heat transfer; casting; phase change; COMSOL Multiphysics; Technology and Engineering;

    Abstract : In this project, the cooling and solidification processes for a Valmet Foundry product have been simulated in order to shorten the cooling time. The study has also been done in cooperation with RISE Swecast in Jönköping, as a part of finding ways to make casting procedures more energy efficient. READ MORE

  4. 3. Residual Stresses Induced by Welding in High Performance Steel

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Rebecca Erlingsdotter Stridsman; Felicia Månsson; [2018]
    Keywords : Residual Stresses; High Performance Steel; Heat transfer; Abaqus; Welding;

    Abstract : Today, high performance steel as a construction material is treated as conventional steel in the European standards. Referring to the Eurocodes, the buckling curves for dimensioning of steel constructions only presents values up to steel grade S460, meaning that the full potential of high performance steel is not considered.

  5. 4. MIG/MAG brazing with Cold Metal Transfer

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : MARIE ALLVAR; [2012]
    Keywords : CMT; Cold Metal Transfer; forceTIG; Plasmatron; brazing; arc brazing; laser brazing; automotive; zinc coated; galvanised; lap joint; CMT; Cold Metal Transfer; forceTIG; Plasmatron; lödning; båglödning; laserlödning; fordonsindustri; förzinkad; överlappsfog;

    Abstract : In the automotive industry a commonly used material is thin steel sheets coated with a thin layer of zinc for corrosion resistance purposes. Welding of this material, with the high temperatures involved, causes problems with zinc burn-off leading to reduced corrosion resistance. READ MORE

  6. 5. Regulation of non-specific lipid transfer proteins in abiotically stressed Physcomitrella patens

    University essay from Molekylär genetik

    Author : Sandra Jansson; [2011]
    Keywords : Abiotic stres; cuticle; non-specific lipid transfer protein; Physcomitrella patens; qRT-PCR;

    Abstract : Non-specific lipid transfer proteins is a large and diverse protein family found in plants, with roles in biological systems ranging from long distance signaling to plant pathogen defense. Little is known about the roles of nsLTPs, but recent studies have cast some light on the issue, among other things proposing that they may be involved in the cutice formation on land-living liverworts, mosses and non-seedbearing plants.
