Abstract
The 1400 degrees C isothermal section of Ti-Al-Nb system was determine d using the diffusion couple technique, along with optical microscopy and electron probe microanalysis (EPMA). Equilibrated alloys were empl oyed to identify the phase regions using XRD. The isothermal section c onsists of seven single-phase regions including beta(beta Ti,Nb), alph a(alpha Ti), gamma(TiAl), eta((Ti,Nb)Al-3), sigma(Nb2Al), delta(Nb3Al) , and gamma(1). The detailed studies on the gamma(1) phase were made b y XRD, DTA, and DSC.
