摘要	The dual phase nanosized (TiBinf2/inf-Ti5Siinf3/inf)/TiAl composites were successfully fabricated using in situ method of combustion synthesis and hot press consolidation. The effects of proportions of the in situ dual phase nanoparticles (TiBinf2/inf and Tiinf5/infSiinf3/inf) on microstructures and compression properties of the composites were investigated. Compared with the monophase TiBinf2/inf and Tiinf5/infSiinf3/inf particles, dual phase TiBinf2/inf-Tiinf5/infSiinf3/inf particles exhibit more obvious grain refinement effect. The grain size of TiAl alloy was refined from 66 to 12 mm with the the generation of dual phase TiBinf2/inf-Tiinf5/infSiinf3/inf particles. Moreover, the TiAl matrix composites reinforced with dual phase nanosized TiB2-Ti5Si3 particles exhibit better comprehensive compression properties. When TiBinf2/inf:Tiinf5/infSiinf3/inf = 2:1[S(TiBinf2/inf + Tiinf5/infSiinf3/inf) = 4 vol.-%], the TiAl matrix composite has a high true fraction strain of 26.1%, a true yield strength of 761 MPa and an ultimate compression strength of 1647 MPa. 2015 Institute of Materials, Minerals and Mining.
