1. A product, comprising a material having:
nickel; and
at least one rare earth element, wherein the at least one rare earth element is present in the material in a weight percentage in a range of about 2% to about 20% relative to a total weight of the material,
wherein the material is characterized as having a feature selected from the group consisting of: dendrites in the material with an average spacing between the dendrites in a range of about 0.5 microns to about 30 microns, cellular dendrites in the material with an average spacing between the cellular dendrites in a range of about 0.05 microns to about 2 microns, and disconnected rare-earth-containing intermetallic particles in the material with an average intermetallic particle spacing in a range of about 0.05 microns to about 5 micron.
