Chapter 12, Problem 12.77P

Interpretation Introduction

Interpretation:

The reason for the eutectoid steel exhibiting different yield strength and percent elongations needs to be explained.

Concept Introduction:

Yield stress or yield strength of metals isthe material property which is defined as the stress at which a material begins to deform plastically whereas yield pint is the point where non-linear deformation begins. The yield point is the point on a stress-strain curve which indicates the limit of elastic behaviorand beginning the plastic behavior percent elongation is defined as a material will plastically and elastically deform up to feature. Percent elongation is one way to measure and quality the ductility of a material.
