Abstract
The effect of notch root radius on the mode I fracture toughness of Ti–18Al–8Nb alloy in beta solution treated and water quenched condition was investigated. The apparent fracture toughness KIA was found to be independent of the notch root radius below a critical notch root radius ρ0 and subsequently increase linearly with the square root of notch root radius ρ1/2 beyond ρ0. The critical notch root radius in this alloy was found to be ∼50 μm. The results were explained on the basis of strain controlled fracture model.
