Chapter 16, Problem 75E

Interpretation Introduction

Interpretation : The composition of gamma-prime phase in Aluminum-Nickel super alloy should be determined.

Concept Introduction :

Super alloys exhibit excellent properties like high resistance to deformation, high tensile strength different and unusual structural features and more perfection than the usual crystalline solids.

Gamma prime phase ( $\gamma \text{'}$ ) is a phase that can be found in the lattice structure of super alloys. Cube faces and cube edges in the gamma prime phase is usually occupied by the metal atoms in the super alloy. Each atom at the edges is shared by eight unit cells. Each atom at the face of a unit cell is shared by two unit cells.
