1. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms
Master-uppsats, KTH/HållfasthetsläraSammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER
2. SFEER Hydrogen Permeation : Finding a suitable coating for the PA6 liner
Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6. LÄS MER
3. Design of a test rig for in situ hydrogen charging of rolling element bearings under load
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/MaskinelementSammanfattning : This Master's thesis is part of the Hydrogen Embrittlement in Rolling element bearings project (HERo) initiated at Luleå University of Technology (LTU), with the primary objective of determining critical hydrogen concentrations in bearing steel for rolling element bearings. The specific aim of this Master's thesis is to design a test rig that enables the investigation of the effects of hydrogen embrittlement on rolling element bearings under load. LÄS MER
4. Effect of Proton Irradiation on the Mechanical Properties of Fe-10Cr-4Al in Liquid Lead
Master-uppsats, KTH/FysikSammanfattning : Among the structural materials under consideration for future lead-cooled fastreactors, special attention is paid to ferritic Fe-10Cr-4Al due to its superior corrosionand erosion protective properties, as well as its insensitivity to liquid metalembrittlement in liquid lead. This thesis gives an inside look into the radiation damageproperties of the alloy and the possible embrittlement scenarios. LÄS MER
5. Influence of hydrogen and carbides on high temperature cracking in cast Inconel
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. LÄS MER
