Chapter 4, Problem 4.24P

Interpretation Introduction

(a)

Interpretation:

The miller indices of the slip directions in the FCC unit cell on the $\left(111\right)$ plane needs to be determined.

Concept Introduction:

In the material science, a set of symmetrically same slip planes having directions for the dislocation motion resulting plastic deformation is described. The geometry of metal is changed due to an external force that causes the crystal lattice to slide over each other. The slip systems present in the material depends on the type of lattice. It specifically occurs in close-packed planes and in closed-packed directions. The magnitude is represented by the Burgers vector.
