Alpha\Beta Titanium alloys such as Ti-6Al-4V often undergo beta annealing to improve fatigue crack growth resistance. Under certain processing paths the grain growth may exhibit abnormal growth kinetics, which leads to coarse grains that may be detrimental to component durability. Previous studies have suggested this is a texture-controlled process which relies on spatial non-uniformities in grain boundary mobility and energy, giving a select few grains an advantage for growth. This work uses Monte Carlo simulations of grain growth to systematically study the most important factors leading to coarse grain development. The texture-controlled nature of coarse grain growth is explored by considering the influence of grain boundary mobility and energy as a function of misorientation, as well as the stored energy of the grains.
