摘要：

Several ternary alloys were designed to help understand the type of substitution and the nature of transformation in L1(2)-type ternary (Fe or Ni) titanium aluminides. X-ray powder diffraction analysis, scanning electron microscopy and microhardness measurements were used to delineate the phases present in arc-melted alloys that were annealed at 1300 K for 10 days. The results of this study show that, in L1(2) type ternary (Fe, Ni) titanium aluminides, Fe or Ni substitutes for Ti, and these materials are TiAl2-based, contrary to previous assumptions.
