The possible crystal structure has been suggested to be tetragonal lattice with a =0.558─0.584 nm, c =0.815—0.845 nm, based on the results from selected area electron diffraction pattern( SADP). The composition of γ1-phase has been obtained by EDS. The supercell reflection spots of Ll_0(TiAl) sructure have also been found in the alloy containing Nb up to 11at.-%. Thus, the transformation from L1_0(TiAl) structure to γ1 is a continuous ordering process with the substitution of Nb atoms for Ti atoms in alloys.
