  1. 21. Diffusion in the liquid Co binder of cemented carbides: Ab initio molecular dynamics and DICTRA simulations

    University essay from KTH/Materialvetenskap

    Author : Martin Walbrühl; [2014]
    Keywords : Ab initio; molecular dynamics; AIMD; DICTRA; cemented carbides; hardmetals; diffusion; liquid Co; cobalt; binder phase;

    Abstract : A fundamental quantum mechanical modelling approach is used for calculating liquid diffusion parameters in cemented carbides. Up to now, no detailed description of diffusion for alloying elements in a liquid Co matrix is available. READ MORE

  3. 22. Stress test methods : a potential approach to hurry up shelf-life tests on oat products

    University essay from SLU/Dept. of Food Science

    Author : Klara Stenmark; [2013]
    Keywords : ASLT; Q10- modeling; indirect conditions; oat-base; oat quality assurance; Arrhenius equation;

    Abstract : The aim of this Master’s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. READ MORE

  4. 23. RETRIEVING THE HEIGHT OF THE PLANETARY BOUNDARY LAYER OVER STOCKHOLM FROM LIDAR MEASUREMENTS

    University essay from Lunds universitet/Fysiska institutionen

    Author : Ewa Johansson; [2013]
    Keywords : Planetary Boundary Layer; Meteorology; weather forecast; Raman LIDAR; Physics and Astronomy;

    Abstract : LIDAR data from the Polly system on the roof of the Arrhenius laboratory at Stockholm University are used to determine the planetary boundary layers (PBL) height distribution. To this end, a wavelet covariance transform method is employed to analyze LIDAR measured data signals from the years 2011-2012. READ MORE

  5. 24. Tool wear in titanium machining

    University essay from Institutionen för kemi - Ångström

    Author : Stina Odelros; [2012]
    Keywords : Tool wear; titanium machining; WC Co cutting tool; tool wear prediction; cutting temperature;

    Abstract : The present work was performed at AB Sandvik Coromant as a part in improving the knowledge and understanding about wear of uncoated WC/Co cutting tools during turning of titanium alloy Ti-6Al-4V. When machining titanium alloys, or any other material, wear of the cutting tools has a huge impact on the ability to shape the material as well as the manufacturing cost of the finished product.
