Mechanical　properties　of　the　TiAl　alloy　produced　by　centrifugal　spray　deposition　(CSD),　compared　to　that　produced　by　ingot　metallurgy　(IM),　were　investigated　at　different　temperatures　from　293　to　973K.　The　result　shows　that　the　ultimate　strength,　yield　strength　and　plasticity　of　the　CSD　TiAl　alloys,　with　excellent　compression　properties　and　plasticity,　are　higher　than　those　of　as-cast　TiAl　alloys　at　room　temperature　as　well　as　at　high　temperature.　There　exists　a　critical　temperature　of　873K　in　the　relationship　between　strength　and　temperature,　in　which　strength　increases　with　increasing　temperature　above　873K.　The　effects　of　CSD　on　mechanical　properties　of　the　TiAl　alloy　are　discussed,　and　the　higher　strength　with　moderate　ductility　achieved　is　because　of　the　finer　lamellar　structure　got　in　the　CSD　processing,　and　this　structure　is　also　believed　to　be　beneficial　to　ductility.
