1. 1. Influence of hydrogen on mechanical properties, microstructure and fracture surface of stainless steel 316L and stainless steel 304

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Mustafa Adnan Tawfeeq Salman; [2020]
   Keywords : Hydrogen embrittlement; stainless steel; microstructure; hydrogen charging; slow and fast strain rate.; Väteförsprödning; rostfritt stål; mikrostruktur; väte laddning; långsam och snabb töjnings hastighet;

   Abstract : Since hydrogen is an alternative energy source and has both economic and environmental benefits, it has received more attention. To use hydrogen a certain condition must be met, safe pressurized containers which are often made of metal. The metal isrequired due to the high mechanical strength and reasonable cost. READ MORE

3. 2. Reduction of hydrogen embrittlement on Electrogalvanized Ultra High Strength Steels

   University essay from Uppsala universitet/Institutionen för kemi - Ångström

   Author : Adam Haglund; [2014]
   Keywords : hydrogen embrittlement; electrogalvanized; ultra-high strength steel; martensite; vacuum evaporation; decarburization; hydrogen relief treatment; väteförsprödning; elförzinkning; ultrahöghållfast stål; martensit; vakuumförångning; ytavkolning; väteutdrivning;

   Abstract : Ultra-high strength steels is known to be susceptible for hydrogen embrittlement at very low concentrations of hydrogen. In this thesis three methods to prevent or reduce the hydrogen embrittlement in martensitic steel, with tensile strength of 1500 MPa, were studied. READ MORE

4. 3. Slow strain rate testing of welded copper

   University essay from KTH/Materialvetenskap

   Author : Kirti Teja Pasupuleti; [2013]
   Keywords : copper canister; friction stir welding; slow strain rates; creep test; knock-mecking model;

   Abstract : In Sweden spent nuclear fuel is planned to be placed 500 m down in the bedrock. The spent nuclear fuel will be contained in copper canisters. The reason behind the selection of copper is its thermodynamic stability against corrosion in the depository. The copper will be exposed to mechanical loading and will be plastically deformed due to creep. READ MORE

5. 4. Hydrogen-assisted stress corrosion cracking of high strength steel

   University essay from KTH/Materialvetenskap

   Author : Rohollah Ghasemi; [2011]
   Keywords : Hydrogen assisted stress corrosion cracking; Hydrogen embrittlement; High strength steel; Slow Strain Rate Test;

   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 microstructure, 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

6. 5. 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
