1. An alloy, comprising:
aluminum;
a rare earth element; and
an alloying element selected from the group consisting of: Si, Cu, Mg, Fe, Ti, Zn, Zr, Mn, Ni, Sr, B, Ca, and a combination thereof,
wherein the aluminum (Al), the rare earth element (RE), and the alloying element are characterized by forming at least one form of an intermetallic compound,
wherein an amount of the rare earth element in the alloy is in a range of about 1 wt. % to about 12 wt. %,
wherein an amount of the alloying element in the alloy is greater than an amount of the alloying element present in the intermetallic compound,
wherein the amount of alloying element present in the intermetallic compound is a portion of the amount of alloying element in the alloy.
