Abstract

Fractures of single-crystal turbine blades of GTP of alloys GS26-VI and GS32-VI after operating damage were analyzed to identify fracture mechanism. Single-crystal samples of alloy GS32-VI were tested under short-term loading and creep at temperature of 570°С, which corresponded to working conditions of blade tails, to confirm the fracture mechanism.
