A Snapshot of Your Day
The severe operating conditions encountered in a gas turbine require high performance materials with the ability to withstand high mechanical loading in combination with high temperatures. The start/stop cycle of the gas turbine gives rise to a cyclic variation of both temperature and load, which may cause crack initiation and propagation due to thermomechanical fatigue (TMF). Knowledge of the TMF crack growth behavior is of vital importance for the fatigue life prediction of gas turbine components.
How You'll Make an Impact
The aim of this master thesis is to characterize the TMF crack growth behavior of a cast nickel base superalloy and investigate how this is influenced by the microstructure. Precision cast gas turbine components typically have complex geometries with large variation in grain size within the casting and therefore the grain size influence is of particular importance. Crack growth testing has been performed in advance of the thesis work on specimens with different grain sizes. Additional crack growth testing will be a part of the thesis work. Microstructural and fractographic investigation of the tested specimens will constitute a major part of the thesis work. Test data analysis and a literature survey will also be required to evaluate the correlation between microstructure and crack growth resistance.
What You Bring
* Ongoing Master of Science in a relevant field, and you are interested in working both theoretically and practically.
* It is an advantage if you have practical experience with mechanical testing and/or microscopy.
