The effect of grain size on deformation twinning in commercially pure titanium was investigated. In order to generate different grain sizes, the samples were subjected to cold rolling followed by annealing. Tensile tests were carried out on material with a range of different grain sizes (10-70 μm) at room temperature. To investigate twinning formation during plastic deformation, separate tensile tests were carried out to strains of 5% and 10%. The number of twins per grain and volume fraction of twins was measured. The results reveal the important influence of grain size on deformation twinning activity. The results will lead to better material models.
