The　effect　of　initial　texture　on　the　twinning　behaviors　of　pure　titanium　during　uniaxial　compression　was　investigated　by　electron　backscattered　diffraction　(EBSD)　technology.　The　{11−22}　and　{10−12}　twinning　variant　selection　behaviors　were　investigated　by　the　Schmid　factor　(SF),　strain　compatibility　factor　(m′)　and　twinning　strain　tensor.　For　{11−22}　contraction　twins,　multiple　twin　variants　are　more　likely　to　form　within　a　grain.　For　{10−12}　extension　twins,　however,　single　variant　is　usually　observed　within　one　grain.　The　variant　selection　of　{10−12}　twinning　is　more　favorable　to　follow　the　SF　law　than　that　of　{11−22}　twinning.　However,　both　{11−22}　twinning　and　{10−12}　twinning　variant　selection　behaviors　can　be　well　explained　by　the　twinning　strain　tensor.　The　activated　{11−22}　twinning　or　{10−12}　twinning　variants　can　well　accommodate　the　deformation　along　the　compression　direction.　For　intragranular　cases,　when　multiple　twins　are　generated　within　a　grain,　most　of　the　activated　variants　have　high　SF　values,　and　both　{11−22}　twinning　and　{10−12}　twinning　activities　show　stronger　orientation　dependence.　For　intergranular　twin　pairs,　the　strain　compatibility　is　related　to　their　formation　sites.　The　twin　pairs　forming　in　the　common　boundaries　of　the　two　grains　have　good　strain　compatibility.　However,　twin　pairs　at　those　triple　junctions　show　poor　strain　compatibility.　©　2020　Elsevier　Inc.
