3. 2. Thermo-mechanical Fatigue Crack Propagation in Inconel 718

   Författare :Lars Jacobsson; Materialteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crack closure; image analysis; potential drop; in-situ scanning elecron microscopy; crack propagation experiments; Thermo-mechanical fatigue; Inconel 718;

   Sammanfattning : Thermo-mechanical fatigue crack propagation in Inconel 718 has been studied with different methods. In-situ observations with a scanning electron microscope (SEM) were performed, the crack propagation process was followed cycle by cycle and the influences from load, temperature, and microstructure on the crack growth were analyzed.

4. 3. Railway wheel steel behaviour upon thermo-mechanical loadings

   Författare :Erika Steyn; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual stress; thermo-mechanical fatigue; railway wheel steel; pearlitic microstructure; severe block braking; repair welding;

   Sammanfattning : Optimised railway maintenance techniques such as rail grinding and milling, or rail repair welding, are vital to more sustainable rail networks. As demands on the railway increases, the need to better understand the material behaviour during local heating events occurring during maintenance is amplified. LÄS MER

5. 4. Low Cycle Fatigue and Thermo-Mechanical Fatigue of Uncoated and Coated Nickel-Base Superalloys

   Författare :Svjetlana Stekovic; Torsten Ericsson; Hael Mughrabi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AMDRY997; CMSX-4; SCB; Thermo-Mechanical Fatigue; Coatings; Gas Turbine; IC1; IC3; IN792; Low Cycle Fatigue; Nickel-Base Superalloys; RT22; Materials science; Teknisk materialvetenskap;

   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

7. 5. Thermo-mechanical modelling of welding with experimental verification

   Författare :Mats Näsström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

   Sammanfattning : Residual stresses and deformations after welding were studied numerically and experimentally. The numerical simulations were performed using the finite element method. In the calculations a thermoelastoplastic material model was used. LÄS MER
