1. Oxidation, Creep and Fatigue Synergies in Cast Materials for Exhaust Manifolds
Sammanfattning : The future development of engines of heavy-duty vehicles towards reduced CO2 emission will increase the exhaust gas temperature and render the exhaust atmosphere more corrosive. The current service material of exhaust gas components - a ferritic ductile cast iron called SiMo51 - will soon meet its upper-temperature limit. LÄS MER
2. On Low-Cycle Fatigue
Sammanfattning : The experimental results presented confirm the anticipation that it is extremely important not to confuse the concept of 'static loading' with the one of 'monotonic loading'. In principle three different crack configurations were investigated in: edge-cracks, internal flaws and surface cracks. LÄS MER
3. Comparability of Railway Rail Steels Low Cycle Fatigue Behaviour
Sammanfattning : Several different kinds of steel are used for railway rails. From simple pearlitic steels for rarely used tracks over premium pearlitic steels for high performance lines to special bainitic, martensitic and austenitic steels for switches and crossings. Most of these steels have been trial and error developed over time in track. LÄS MER
4. Low Cycle Fatigue and Thermo-Mechanical Fatigue of Uncoated and Coated Nickel-Base Superalloys
Sammanfattning : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. In such environments superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface. LÄS MER
5. Interfacial Reactions and Low Cycle Fatigue of Lead-Free Solders for Electronic Packaging
Sammanfattning : Two key technologies used by the electronics industry are chip technology and packaging technology. Solder plays a crucial role in both of them. During the last decade, there has been a strong worldwide environmental movement towards lead-free electronic products. LÄS MER
