  1. 1. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Chun Hei Ho; [2023]
    Nyckelord :Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Sammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER

  3. 2. Investigation of new hot melt adhesives with plasticisers based on renewable resources : Investigating the use of sustainable plasticisers in hot melt adhesives

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Shadi Feyzabi; [2023]
    Nyckelord :Hot melt adhesives; renewable; mineral oil; vegetable oil; rheology; viscosity; loop tack; adhesive strength; Smältlim; förnybar; mineralolja; vegetabilisk olja; reologi; viskositet; loop tack; vidhäftningsstyrka;

    Sammanfattning : Hot melt adhesives (HMA) are a class of adhesives that, unlike solvent-or waterborne counterparts, do not contain organic solvents or other carriers, and are produced and subsequently applied in a molten state. The main components of HMA are polymers, tackifying resins, and a plasticiser. LÄS MER

  4. 3. Apparent density for water atomized low-carbon steel powder

    Master-uppsats, KTH/Materialvetenskap

    Författare :Simon Lindström; [2023]
    Nyckelord :;

    Sammanfattning : Carbon content does not affect the apparent density for water atomized iron powder monotonically. At low carbon content, around 0.1 wt %, apparent density is higher than a similar powder with 0.3 wt % carbon. LÄS MER

  5. 4. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Thibault Desjonquères; [2022]
    Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

    Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER

  7. 5. En Jämförelse Mellan Rheogjutning Och Konventionell Pressgjutning Med Vakuum. : Vid Tillverkning Av Aluminiumkomponenter.

    M1-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Marisa Ling Brännlund; Hanna Martinsson; [2021]
    Nyckelord :semi-solid; rheocasting; rheogjutning; pressgjutning med vakuum; gjutning; RheoMetal;

    Sammanfattning : The car industry is constantly under pressure to be competitive in their product development which includes not only safety and increased performance, but also in their environmental impact. Volvo Cars strives to be more environmental and high performing in their product development, which of course includes manufacturing methods since these highly effect a components environmental impact and mechanical performance.
