The　commercial　pure　titanium　plate　was　shot　vertically　by　the　projectile　with　a　diameter　of　7.62mm　at　impact　velocities　ranging　from　782m/s　to　825m/s.　The　microstructure　around　the　crater　of　commercial　pure　titanium　plate　was　analyzed　by　optical　microscopy　(OM)　and　electron　backscatter　diffraction　(EBSD)　methods.　It　was　found　that　different　microstructures　were　observed　along　the　depth　of　cater.　In　upper　region　of　the　crater,　grains　were　deformed　and　fragmented.　Adiabatic　shear　bands　(ASBs)　were　observed　in　the　middle　of　the　crater,　and　some　ASBs　were　bifurcated.　At　the　bottom　of　the　crater,　the　grains　were　less　deformed,　and　the　deformation　twins　were　formed.　The　microstructures　in　the　center　of　adiabatic　shear　band　were　mainly　consisted　of　the　dynamic　recrystallization　grains　and　sub-grains.　The　microstructure　in　the　transition　region　was　elongated　grains　along　the　shear　stress　distribution.　©　2016　Trans　Tech　Publications,　Switzerland.
