Effect of notch severity and crystallographic texture on local deformation and damage in commercially pure titanium

•Initial crystallographic texture notch severity controls deformation and damage micro-mechanisms in CP-Ti•Off-basal (BA) orientation shows higher apparent yield stress, greater plastic deformation, better notch strength ratio value than prismatic-pyramidal (PP) orientation•Extensive extension twinning in BA samples compared to PP samples which increases with notch severity from unnotched to U and V notch samples•Combination of dominant prismatic slip and crystallographic texture contributes to higher diffuse necking in BA sample and higher fraction of fluted voids in PP sample•Symbiotic role of texture and notch severity decides deformation and damage mechanisms in CP-Ti
