11. Very high cycle fatigue of tool steels
Sammanfattning : An increasing number of engineering components are expected to have fatigue life in the range of 107 - 1010 load cycles. Some examples of such components are found in airplanes, automobiles and high speed trains. LÄS MER
12. Predicting Sheared Edge Characteristics of High Strength Steels
Sammanfattning : An efficient way of reducing CO2 emissions from the transportation sector is to reduce the vehicle weights, i.e. lightweighting. A common strategy for lightweighting of vehicles is to replace the steels used to build structural parts of the vehicle, usually manufactured by metallic sheets, with stronger, advanced high strength steel (AHSS) grades.

13. High temperature tribology of high strength boron steel and tool steels
Sammanfattning : There are many tribological interfaces that are exposed to elevated temperatures. Typical examples are the interfaces of various moving assemblies, for examples in aerospace industry, power generation and metalworking processes. LÄS MER
14. Weld Metal Properties for Extra High Strength Steels
Sammanfattning : .... LÄS MER
15. Dissimilar joining of aluminium to ultra-high strength steels by friction stir welding
Sammanfattning : Multi-material structures are increasingly used in vehicle bodies to reduce weight of cars. The use of these lightweight structures is driven by requirements to improve fuel economy and reduce CO2 emissions. The automotive industry has replaced conventional steel components by lighter metals such as aluminium alloy. LÄS MER
