2018-7-8  Rare-earth element, any member of the group of chemical elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through lutetium [Lu]).

Rare Earth an overview ScienceDirect Topics

Rare earths containing alloys are two types with small additions < 1% and > 30%. Alloys with rare earths containing less than 1% alloying elements, includes addition of misch metal or cerium to nodularize cast iron or for controlling the inclusion shapes in steels.
