Chapter 23, Problem 23.85(choose chapter or problem)
As mentioned in the text, Ni3Al is used in the turbines of aircraft engines because of its strength and low density. Nickel metal has a cubic close-packed structure with a face-centered cubic unit cell, while Ni3Al has the ordered cubic structure shown in Figure 23.17(b). The length of the cubic unit cell edge is 3.53 A for nickel and 3.56 A for Ni3Al. Use this data to calculate and compare the densities of these two materials.
