Chapter 9, Problem 9.25P

Interpretation Introduction

Interpretation:

The grain size hardening and strain hardening mechanisms needs to be compared.

Concept introduction:

Hardening is the process of making any material physically harder by strengthening the material with the help of various treatments. It is the metallurgical process which is used to increase the hardness of a metal. The hardness is of material particularly metal is directly proportional to the uniaxial yield stress at the location of the imposed strain.
