The contour lines of solidification reaction temperatures and eutectic(γ+γ′) volume fraction in the Ti-Ta-Nb compositional triangle were determined by DTA andimaging analyzer. Compared with the reference alloy IN738LC, in most of the compositionalranges studied, the designed alloys show very low amount of eutectic (γ+γ′), ≤0.4 v.-%, low-er solidification range, ≤65℃, and wider "heat treatment window", >100℃, which indi-cates that the alloys should have the promising microstructural stability, single crystalcastability and be easier for complete solution treatment. In wide compositional ranges, thedesigned alloys showed good hot corrosion resistance (mass loss less than 20 mg / cm~2 after24 h kept in moiten salt at 900℃). By summarizing the results, the promising alloy,compositional ranges with balanced propertise were determined for the final alloy design step,i.e., the single crystal growth and mechanical property characterization of the alloys selectedfrom the above regions.
