In　this　paper,　the　Ti-Al-Sn-Zr-Mo-Si　series　high　temperature　titanium　alloy　is　designed　by　using　the　electron　concentration　theory　and　the　first　principles　calculation.　The　ingot　of　a　novel　high　temperature　alloy　was　prepared　by　induction　skull　melting　(ISM)　in　a　water　cooler　copper　crucible,　then　three　different　kinds　of　forging　technology　(two　steps　of　axial　forging,　two　steps　of　lateral　forging　and　two　steps　of　multi-directional　forging)　are　employed　for　the　Sub　beta　forging　at　1050　degrees　C　and　the　near　beta　forging　at　980　degrees　C.　It　shows　a　basket-weave　microstructure　after　sub　beta　forging　at　1050　degrees　C.　While　after　the　near　beta　forging　at　980　degrees　C,　the　alloy　shows　a　duplex　microstructure　with　a　little　amount　of　primary　alpha-phase　and　mechanical　properties　is　better　than　the　alloy　forging　at　1050　degrees　C.　The　grains　undergoing　a　two　steps　of　multi-directional　forging　is　finer　and　more　uniform,　and　the　properties　is　more　excellent　for　the　alloy.
