On Competitive Dendrite Growth in Single Crystal Ni-Base Superalloys
Abstrakt
Ni-base single crystal superalloys are used to make blades for gas turbines operating in aero engines and power plants. They have to withstand mechanical loads at temperatures close to their melting point. They are produced via an ingot-metallurgy route involving directional solidification, constitutional undercooling, and dendrite growth. The lecture focuses on how dendrites grow and how collective dendrite growth phenomena account for crystal mosaicity. Dendrite interactions are studied with a special focus on branching and extinction events.
This lecture is organized as part of the project “Partnership for Security in Sustainable Transport and Energy (PSSITE)”, Reg. No. CZ.02.01.01/00/23_020/0008549, co-financed by the European Union.
