  1. 1. Analysis of granulated carbide powder and how it affects pressing

    University essay from KTH/Materialvetenskap

    Author : Maeva Anfossi; Emma Hjortzberg-Nordlund; Linnéa Lundemo Mattsson; [2023]
    Keywords : Cemented Carbide Tools; Pressing Agent; Flowability; Tap Density; Angle Of Repose; Hall Flow Time; Particle Size Distribution; Powder Rheometer; Compatibility; Hårdmetallverktyg; Pressmedel; Flytbarhet; Tapp Densitet; Rasvinkel; Hall Flödestid; Partikelstorleksfördelning; Pulverrheometri; Kompatibilitet;

    Abstract : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. READ MORE

  3. 2. Automation of powder level reading in a tap density test

    University essay from KTH/Materialvetenskap

    Author : Tim Juréen; Sigrid Karlsson; [2021]
    Keywords : ;

    Abstract : When using metal powder in any form of production, it needs to be stored, handled and transported. To do this effectively, it is of importance to know how the powders flow and this is governed by a behaviour called flowability. One method of assessing powder flowability is by comparing changes in powder density. READ MORE

  4. 3. Influence of structural and materials properties on the flexural strength of laminated high-density cellulose fiberboards

    University essay from KTH/Hållfasthetslära

    Author : Ola Serck; [2021]
    Keywords : ;

    Abstract : Laminated pressboard is a structural electrical insulation material used in power transformers. Typical applications are areas in the power transformers where high mechanical forces are present such as pressrings or winding tables and cleats which support the electrical cables connecting the transformer windings to tap-changes and bushings.

  5. 4. Characterizing flowability of metal powders

    University essay from KTH/Materialvetenskap

    Author : David Correa Zapisotski; Martin Wallhed; [2019]
    Keywords : Powder Metallurgy;

    Abstract : Powder metallurgy is a growing field with much potential. The core purpose and problem in this work is attempting to describe and understand what and how metal powder properties impact powder flowability. READ MORE

  6. 5. Near-local density approximation approach to one-dimensional lattice systems

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Basheer Joudeh; [2018]
    Keywords : DFT; Hartree; Hartree-Fock; LDA; BALDA; Mean-field; Hubbard; SOFT; Physics and Astronomy;

    Abstract : Describing many-body quantum systems has been an analytically and computationally challenging task since the advent of quantum mechanics. However, in the past 50 years as a result of our technological advancement and the emergence of methods such as density-functional theory (DFT), we have taken crucial steps forward regarding our ability to study and understand large quantum systems.
