Nickel Based Super Alloy Turbine Blade Investment Casting

[PDF] Progress on modeling and simulation of directional ...

Directional solidified turbine blades of Ni-based superalloy are widely used as key parts of the gas turbine engines. The mechanical properties of the blade are greatly influenced by the final microstructure and the grain orientation determined directly by the grain selector geometry of the casting. In this paper, mathematical models were proposed for three dimensional simulation of the grain ...
