Experimental Investigation of Phase Equilibria in the Ti—Al—Zr System at 1000–1300 °C

Four partial isothermal sections of the Ti—Al—Zr system up to 60 at. % Al and 30 Zr were experimentally established between 1000–1300 °C. Six heat-treated alloys analysed by scanning electron microscopy, transmission probe microanalysis, conventional high-energy X-ray diffraction, differential thermal analysis. Phase equilibria determined B2-ordered (β0), βTi,Zr, αTi, Ti3Al, TiAl, ZrAl2.
