TiAl alloy workpieces were prepared using titanium powder or titanium hydride power and aluminum powder as raw material by low-temperature sintering, gel-casting, batching out and pressureless sintering. The results show that the TiAl alloy powder can be obtained by heating titanium powder and aluminum power for 2 h at 500 oC and 3 h at 600 oC, or heating titanium hydride power and aluminum powder for 3 h at 750 oC. The last sintering process is 2 h at 1450 oC and 2 h at 1400 oC for the two kinds of processing. The relative density are 91% and 96.75%, respectively
