Abstract
The effect of the change in microstructure produced by means of different heat treatments on mechanical properties and fracture topography of a Ti-6Al-4V alloy has been studied. It has been demonstrated that an acicular microstructure produces a loss of ductility independently of its morphology. However, this morology has a strong influence on toughness. The coarse acicular microstructure obtained by air cooling from the β phase shows the highest toughness. However, the fine needles of α′ martensite produced by water quenching from the β phase have the lowest values. The different fracture mechanisms and the crack growth path tortuosity justify this change in behaviour.
