Section I: Basic and Applied Research


Differential thermal analysis (DTA) was used to determine the solidus and liquidus surfaces of the iAl-rich portion of the NiAl-Cr pseudobinary system. The results indicate that depressions in thes esurfaces due to Cr are larger than previously suggested and that the solubility of Cr in NiAl when substituted for AI is enhanced. For Cr contents greater than ≈2 at.%, Al-rich alloys exhibit higher solidus temperatures than do Ni-rich alloys.
