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
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
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
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
5. Low Cycle Fatigue Reliability and Interfacial Reaction of Lead-free Solder Joints for Electronic Packaging
Sammanfattning : Two key technologies in electronics industry are chip technology and packaging technology. Solder plays a crucial role in the assembly and interconnection in the electronic packaging industry. As a joint material, solder provides electronic, thermal and mechanical continuity. LÄS MER
