    Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

  3. 2. Hydrogen-assisted stress corrosion cracking of high strength steel

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Rohollah Ghasemi; [2011]
    Keywords : Hydrogen embrittlement; hydrogen induced cracking; stress corrosion cracking; high strength steel; uniform corrosion; SSRT; hydrogen charging; fractography; hydrogen degradation;

    Abstract : In this work, Slow Strain Rate Test (SSRT) testing, Light Optical Microscopy (LOM) and Scanning Electron Microscopy (SEM) were used to study the effect of micro-structure, corrosive environments and cathodic polarisation on stress corrosion cracking (SCC) of two grades of high strength steels, Type A and Type B. Type A is manufactured by quench and tempered (Q&T) method. READ MORE
