The　microstructures　and　properties　of　Ti-48Al-2Mn-Nb　alloy　formed　by　centrifugal　spray　deposition　(CSD)　were　investigated.　Hot　isostatic　pressing　was　employed　to　remove　the　porosity　of　CSD　samples.　The　tensile　and　compressive　tests　were　carried　out　at　ambient　temperature　and,　especially,　compression　strains　of　1,　3,　5,　10　and　20%,　respectively,　were　also　done.　The　results　show　that　the　ductility　of　CSD　TiAl　alloy　is　around　3%.　On　the　other　hand,　an　excellent　compression　behavior　is　achieved,　which　shows　2210-2310　MPa　of　compressive　strength　and　34-38%　of　compressive　ratio.　The　scanning　electron　microscopy　observations　show　that　the　character　of　slip　bands　is　related　to　the　lamellar　structure　of　TiAl,　which　slips　along　the　interfaces　between　the　layers.　Transmission　electron　microscopy　observations　show　lots　of　twins　and　some　dislocation　lines　built　up　in　the　boundaries　between　lamellar　domains　or　between　the　lamellae.
