Chapter 13, Problem 13.5P

Interpretation Introduction

(a)

Interpretation:

The AISI-SAE number of steel having microstructures $38\%$ pearlite $62\%$ primary ferrite needs to be determined.

Concept Introduction:

Steel is an alloy of iron and carbon. It is the main element of structures, infrastructures, instruments, machinery, equipment, and arms because of its strong tensile strength and small costs. Iron is a stainless steel core metal. Iron takes on two geometric shapes (allotropic shapes),a body-centered cubic and a face-centered cubic.

Interpretation Introduction

(b)

Interpretation:

The AISI-SAE number of steel having microstructure $93\%$ pearlite $7\%$ primary cementite needs to be determined.

Interpretation Introduction

(c)

Interpretation:

The number of AISI-SAE having microstructures $97\%$ ferrite $3\%$ cementite needs to be determined.

Interpretation Introduction

(d)

Interpretation:

The AISI-SAE number having microstructures $86\%$ ferrite $14\%$ cementite needs to be determined.
