EFFECT OF DUCTILE-BRITYLE TRANSITION TEMPERATURE OF Al-Si COATING ON FATIGUE PROPERTIES OF Ni-BASE SUPERALLOYS

摘要

The effect of Al content on the ductile-brittle transition temperature of Al-Si coating and theeffect of fracture behaviour.of the Al-Si coating on the fatigue properties of Ni-basesuperallovs have been investigated to propose the theoretical basis of search for an optimum ofmechanical properties of the high temperature coating on Ni-base alloys.
