Design of variable withdrawal rate for superalloy single-crystal blade fabrication
Stray grains bring great challenges to the production of superalloy single-crystal blades using the Bridgman method. The height difference between the liquidus isotherms in the airfoil and platform, which is induced by the difference between liquidus isotherm advancing velocity and withdrawal rate,...
