This set of lectures is on "Single Crystal Superalloys for Turbine Blade Applications" for the Superalloys & High Performance Materials course part 12. This part of the course was taught by Dr Christopher Daniel at The University of Manchester in 2021.
Video 1 will first focus on the processing and heat-treatment of polycrystalline superalloys and explain how the process can be optimised to produce idealised properties for the turbine disk in a jet engine.
Video 2 will explain the processing stages for single-crystal superalloys that can be used to improve the high temperature properties and creep performance of the turbine blades in a jet engine.
Video 3 will summarise the reasons behind trends for different chemical additions and how they have helped steadily improve the single crystal turbine blade properties, as well as describing the importance of minimising freckling, orientation and grain boundary defects during production.
Video 4 will cover the in-service performance of single crystal turbine blades, explaining the creep performance and the creep process of rafting, summarising the fatigue properties, and explaining the reasons behind coatings and joinings.
The live lecture includes poll questions and discussion for the "Single Crystal Superalloys for Turbine Blade Applications" topic and was recorded on Tuesday 20th April 2021.
