Abstract
A turbine blade having a pre-segmented squealer tip is provided. The segment or slots in the squealer tip are located in regions of maximum stress, and reduce cracking of the squealer tip and propagation of cracks into the airfoil. The slots are preferably filled with a corrosion resistant material which is more ductile than the base alloy.
