英文摘要 | TiAl pre-alloyed powder (nominal composition Ti-47Al-2Cr-2Nb-0.2W-0.15B, atomic fraction, %) was produced by electrode induction melting gas atomization (EIGA) technique. The average diameter is 120.7 mu m, and the distribution of the powder diameter follows Gaussian distribution. The phase constitution is a function of particle diameter. The amount of the gamma phase increases with powder diameter increasing, the finest powder consists of predominantly alpha(2) phase. The alpha(2) phase in the powder was transformed into gamma phase after annealing at temperatures higher than 500 degrees C. Local coarsening was observed in the microstructure of TiAl compact duo to the microsegregation of elements in the powder. The)(PS result indicated that the outer layer of the TiAl pre-alloyed particle consists of a thin layer of Al(2)O(3) and TiO(2). |
