When forging large billets of titanium, microtextured regions can form. After doing a heat treatment above the beta tranus, some grains can grow abnormally coarse. These abnormally coarse grains are expected to affect the mechanical properties such as strength and fatigue strength. Through computational modelling, using LightForm’s in-house code MatFlow and experimental based work like in situ digital image correlation while applying tension. The mechanical properties are to be understood, specifically how and where cracks are likely to form. Some initial modelling results show that strain is highly localised in the grain boundary alpha between the abnormally coarse grains, and it is expected that this localised strain will be the region for crack formation.
