Significant improvement in room temperature ductility of the conventionally cast NiAl alloy was achieved by adding less than 3 at% of Cr and a trace amount of Ce. This improvement has also accompanied with a minor reduction in strength. It was found that the solubility of both the Cr and Ce was increased by their co‐presence in NiAl, which was believed to be a result of forming Cr‐Ce complexes in NiAl.
