  1. 1. Study and empirical modelling of recrystallisation annealing of martensitic chromium steel strip by means of EBSD

    Detta är en avhandling från Stockholm : KTH

    Nyckelord :EBSD; Etching; Metallography; Cold Rolling; Recrystallisation annealing;

    Sammanfattning : Recrystallisation annealing, a repeated heat treatment between different stages of cold rolling of martensitic chromium steel strip, is successful when neither high rolling forces nor wear of the working rolls occur during the subsequent cold rolling. Mechanical properties as tensile strength, yield, elongation or hardness have been, by tradition, the criteria that described the quality of the annealing process. LÄS MER

  2. 2. Friction stir welding of copper canisters for nuclear waste

    Detta är en avhandling från Stockholm : KTH

    Sammanfattning : The Swedish model for final disposal of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. One of the methods to seal the copper canister is to use the Friction Stir Welding (FSW), a method invented by The Welding Institute (TWI). LÄS MER
