Ti-48Al-2Mn-2Nb　alloy　was　produced　by　＇centrifugal　spray　deposition＇　(CSD),　and　then　hot　isostatic　pressing　(HIP)　was　employed　to　remove　the　porosity　formed　by　CSD.　The　effects　of　CSD　and　HIP　processing　on　the　mechanical　properties　and　microstructure　of　the　TiAl　alloy　were　investigated.　The　results　show　that　the　CSD　and　HIP　processing　can　both　improve　the　strength,　plasticity　of　the　TiAl　alloy,　and　the　tensile　elongation　values　of　the　CSD　or　HIP　samples　are　around　3%,　which　are　better　than　those　of　as-cast　TiAl　alloys　in　room　temperature.　Especially,　they　show　more　excellent　compressive　properties　at　ambient　temperature　with　a　compressive　ratio　of　33.8%　and　compressive　strength　of　2210MPa　for　the　CSD　samples,　and　a　compressive　ratio　of　37.8%　and　compressive　strength　of　2348MPa　for　the　HIP　samples.　The　CSD　processing　also　improves　the　fracture　toughness　of　TiAl　alloy,　which　is　much　higher　than　that　of　the　HIP　processing,　while　the　HIP　processing　seems　to　be　beneficial　the　ductility　and　plasticity　as　having　a　duplex　structure.　The　effects　of　CSD　and　HIP　processing　on　microstructure　and　properties　of　TiAl　alloys　are　discussed　to　understand　the　deformation　and　fracture　process　of　the　alloy.
