| Abstract |
| Intermetallic compound TiAl was synthesized by using self-propagating high-temperature synthesis(SHS) method. SHS reaction of TiAl was realized by exothermic reaction between molten Al and solid Ti particles. The synthesis product consisted of TiAl(L1_(0) type) matrix which contains small amount of Ti₃Al as a second phase. The reaction temperature increased from 1477K to 1542K with increment of Al contents in mixed powder, but propagation rate decreased from 0.394 cm/sec to 0.238 cm/sec in the range of 52 at%Al to 54 at%Al. Also, both of reaction temperature and propagation rate in the range of 2.24 g/㎤ to 2.93 g/㎤ of green density increased linearly. |
