The Polythermal Section of Ti-22Al-<i>x</i>Nb (30-78at.%Ti) in Ti–Al–Nb System

The Polythermal Section of Ti-22Al-<i>x</i>Nb (30-78at.%Ti) in Ti–Al–Nb System

The polythermal section of Ti-22Al-<i>x</i>Nb (30–78 at.% Ti) in the Ti-Al-Nb system was studied using X-ray diffraction analysis (XRD), differential thermal analysis (DSC), and electron probe micro-analysis (EPMA). No new ternary compounds were found in this work. The polythermal sectio...
