  1. 1. Irradiation Embrittlement on a Core Shroud from Decommissioned BWR

    Master-uppsats, KTH/Fysik

    Författare :Åsa Bjåland; [2023]
    Nyckelord :hardness; Vickers hardness test; ATT; yield strength; irradiation embrittlement; welds; hårdhet; Vickers hårdhetstest; ATT; sträckgräns; bestrålningsförsprödning; svetsar;

    Sammanfattning : Irradiation embrittlement is a problematic issue for internal structures, such as acore shroud, in a light water reactor. It is characterized by decreased ductility andtoughness, and increased yield strength and hardening due to increased dislocations. LÄS MER

  3. 2. Evaluation of mechanical and fluoride ion release properties of a resin based restorative material, “Cention”

    Master-uppsats, Umeå universitet/Institutionen för odontologi

    Författare :Line Hulsart; Chawanrat Hongseethong; [2022]
    Nyckelord :cention; alcasite; composite resin; glass ionomer; fluorid ion release; dental restoration; compression strength; vickers hardness;

    Sammanfattning : Background: A new permanent dental restorative material, Cention Forte, have recently been introduced. The manufacturer claims that this material has higher compressive strength than glass ionomer as well as positive ion release properties. LÄS MER

  4. 3. Examination of a Damaged Slitting Knife using Scanning Electron Microscopy and Finite Element Simulations

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Love Öman; [2021]
    Nyckelord :slitting; slitting knives; damage; sem;

    Sammanfattning : At voestalpine Precision Strip AB, the slitting process is used frequently. Slitting is a commonly applied manufacturing technique during sheet metal processing that aims to split large coils of sheet metal into narrower widths. LÄS MER

  5. 4. Analysis of a Plate of High Strength Steel: Simulation of Impact and Determination of Residual Stresses

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Martin Hviid; [2021]
    Nyckelord :;

    Sammanfattning : In this study a finite element model has been created in ABAQUS/Standard in order to replicate impact tests performed by SSAB and to determine residual stresses in a plate. Uniaxial tensile tests have been done in order to determine the plastic behaviour of a high strength steel from the manufacturer SSAB and to determine whether the material can be assumed to be isotropic.

  7. 5. Correlating the microstructure with wear properties of aluminium silicon carbides

    Master-uppsats, Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design; Högskolan i Jönköping/JTH, Material och tillverkning

    Författare :Chaitanya Krishna Jammula; [2019]
    Nyckelord :Aluminium silicon carbide; silicon carbide; wear test and scratch test;

    Sammanfattning : Aluminium is one of the metals playing a prominent role in automobile industry after cast iron. Because of its light weight property and good mechanical properties. When aluminium reinforced with silicon carbide showing good tribological properties and improved strength. LÄS MER
