Abstract
The 1400‡C isothermal section of Ti-Al-Nb system was determined using the diffusion couple technique, along with optical microscopy and electron probe microanalysis (EPMA). Equilibrated alloys were employed to identify the phase regions using XRD. The isothermal section consists of seven single-phase regions including Β(ΒTi,Nb), α(αTi), γ(TiAl), η((Ti,Nb)Al3), σ(Nb2Al), δ(Nb3Al), and γ1. The detailed studies on the γ31 phase were made by XRD, DTA, and DSC.
