Chapter 4, Problem 4.73P

Interpretation Introduction

Interpretation:

The mechanism to which strengthening Hall-Petch equation is related should be determined.

Concept Introduction:

The Hall-Petch equation is given as:

  ${\sigma }_y={\sigma }_0+K{d}^{-1/2}$

Here,

The yield strength is ${\sigma }_y$.

The average diameter of grains is $d$.

The constants for the metal are ${\sigma }_0$ and $K$ respectively.
