  1. 21. FEM analysis of existing buildings during renovation

    University essay from KTH/Hållfasthetslära

    Author : Agnes Nyberg; [2023]
    Keywords : Sturegallerian; Räumlich Finite Element Method; Euro code; Masonry; Steel amplifier; Sturegallerian; Räumlich Finita Element Metod; Eurokoder; Murverk; Stål förstärkning;

    Abstract : In this masters thesis the aim was to investigate a part of Sturegallerian in Stockholm to be reconstructed. The reconstruction did implicate that openings were to be established in an already existing masonry wall. READ MORE

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

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

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

    Abstract : 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. READ MORE

  4. 23. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    University essay from Lunds universitet/Materialteknik

    Author : Johan Ranstad; [2023]
    Keywords : Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Abstract : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. READ MORE

  5. 24. Optimization of the process-route of a Nickel-base alloy : Investigation of Sigma-phase precipitation in heat treatment

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Felix Andersson; [2023]
    Keywords : Sigma-phase; austenitic stainless steel; Nickel-base alloy; heat treatment; Sigmafas; austenitiskt rostfritt stål; Nickelbas legering; värmebehandling;

    Abstract : The focus of this master’s thesis is on the heat treatment of Ni-base alloys, specifically the risk of intermetallic σ-phases during different stages of heat treatment. The alloy studied is Sanicro®28, a super-austenitic stainless steel produced by Alleima AB. READ MORE

  6. 25. Resistance Element Welding of Ultra High Strength Steel to Aluminium

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Malte Eriksson; [2023]
    Keywords : ;

    Abstract : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. READ MORE
