A　novel　microstructure　i.e.,　lamellar　bimodal　microstructure　(LBM)　was　prepared　in　high　temperature　ti-tanium　alloy.　The　morphology　of　primary　alpha　phase　and　secondary　alpha　phase　were　tailored　by　hot　rolling　and　cyclic　phase　transformation,　respectively.　The　LBM　possess　the　excellent　tensile　yield　strength　and　elongation　to　failure　of　995.5　MPa　and　16.7　%　at　room　temperature　and　569.5　MPa　and　31.6　%　at　650　degrees　C,　respectively.　The　refined　primary　alpha　platelet　and　secondary　alpha　colony　were　the　main　strengthening　mechanisms　of　LBM　at　room　temperature.　Meanwhile,　the　formation　of　geometrically　necessary　dislocations　provide　an　assistant　work　hardening　effect.　In　addition,　unique　lamellar　bimodal　structure　and　alpha　colony　refinement　enhance　the　hindering　effect　of　secondary　alpha　phase　on　primary　alpha　phase　deformation　at　650　degrees　C.　This　strategy　may　provide　a　new　route　to　design　novel　high-temperature　titanium　microstructure　with　excellent　tensile　properties　at　room　and　high　temperature.(c)　2022　Published　by　Elsevier　B.V.
