Superalloys have been made of nickel and aluminum. The alloy owes its strength to the formation of an ordered phase called the gamma-prime phase, in which Al atoms are at the corners of a cubic unit cell and Ni atoms are at the face centers. What is the composition (relative numbers of atoms) for this phase of the nickel-aluminum superalloy?
