Sammanfattning : High temperature oxidation and corrosion of Ni-based superalloys used for blades in industrial gas turbines was studied using advanced high-resolution electron microscopy methods. Both coated and non-coated alloys were tested. LÄS MER
Sammanfattning : Manufacturing of hot structural components for aero engines requires the materials being used to be weldable. The high demands on strength and temperature resistance make nickel based superalloys the material of choice for this application. LÄS MER
3. Microstructure of Pt modified aluminide diffusion coatings on Ni based single crystal superalloys
Sammanfattning : .... LÄS MER
4. High Temperature Fatigue Crack Growth in a Ni-based Superalloy : Modelling Including the Interaction of Dwell Times
Sammanfattning : Safe life of gas turbines is always of major concern for manufacturers in order to ensure passenger safety and stable continuous power output. An increasing amount of resources have been put into research and development to assure that all safety aspects are covered in the design of new turbines and to ensure that enough frequent service intervals are scheduled to avoid complications. LÄS MER
Sammanfattning : Ni-based superalloys are the important materials for gas turbines in advancedaeroplane engines . The addition of refractory elements to these superalloys,such as rhenium and tungsten, can significantly improve the hightemperatureperformance by so-called solid-solution hardening. LÄS MER
