Abstract

Fracture mechanics and tensile tests have been performed on the metastable β-Ti alloy Ti-IOV-2Fe-3AI. A variety of microstructures was established by several combinations of forging and heat treatment resulting in different types, morphologies, and volume fractions of the a-phase which precipitates from the matrix-β phase. Both fracture toughness and ductility are strongly reduced by increasing hardening by the secondary a-phase. An elongated primary a-phase (α p ) shows higher toughness compared to a globular α p -phase. A thick, continuous subgrain boundary a-film lowers the toughness significantly. For microstructures without primary a a grain boundary α-film does not affect the toughness, while the ductility is drastically reduced. Very attractive combinations of fracture toughness and ductility were found for a microstructure without primary a and without grain boundary α. The results are discussed based on the fractographic observations, and a model is proposed which includes the effect of microstructure and slip distribution on the crack nucleation, the crack growth path, and the crack deviation.
