21. Isothermal and Thermal Fatigue of Martensitic Chromium Hot-Work Tool Steels
Sammanfattning : A lot of our everyday products, e.g. car-parts and mobile phone covers, are shaped by using high temperature techniques, such as die casting, extrusion, forging or rolling. The die in all these forming processes play an important role, since it usually gives the object its final shape. LÄS MER
22. Isothermal low cycle 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. However, the superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface of the superalloys. LÄS MER
23. Prediction of traction in EHL contacts operating in the linear isothermal region
Sammanfattning : The vehicle industry plays an important role in moving people and goods all over the world. Unfortunately, the vehicular transportation has a huge (negative) impact on the climate. Improved fuel-efficient vehicle technologies are therefore required to reduce emissions and address environmental concerns. LÄS MER
24. Mass transfer during isothermal drying of a porous solid containing multicomponent liquid mixtures
Sammanfattning : Mass transfer in a porous solid, partially saturated with asingle solvent and multicomponent liquid mixtures, has beenexperimentally and theoretically studied. A porous materialcontaining single liquids and mixtures of organic solvents wasisothermally dried. LÄS MER
25. Crack growth in single crystal nickel base superalloys under isothermal and thermomechanical fatigue
Sammanfattning : This work concerns the fatigue crack growth behaviour of nickel base single crystal superalloys. The main industrial application of this class of materials is in gas turbine blades, where the ability to withstand severe mechanical loading in combination with high temperatures is required. LÄS MER
