The analysis of the isothermal sections of the Ti-Al-Fe phase diagram resul
ted in the identification of several composition regions of interest for po
ssible alloy developments. Seven TiAl-based intermetallic alloys and three
intermetallic alloys on the basis of Fe-rich phases were selected and prepa
red by induction melting. All phases in these alloys were characterised by
light microscopy, X-ray diffraction and electron-probe microanalysis with r
espect to composition and crystal structure. With the results the isotherma
l section of the Ti-Al-Fe phase diagram at 1000 degrees C was updated. The
alloys were tested mechanically in compression at various temperatures up t
o 1000 degrees C and were characterised with respect to hardness, Young's m
odulus, ratio of plastic and elastic work, yield stress and creep resistanc
e. The mechanical properties of the studied alloys varied within wide limit
s depending on the character and the distribution of the constituent phases
. Alloys of interest for further investigation were identified.
