Chapter 13, Problem 13.20P

Interpretation Introduction

(a)

Interpretation:

From the following graph of heat treatment, The yield strength and tensile strength needs to be determined. The steel is used of 1050 steel with brinel hardness at least 330 and elongation at least 15%.

Concept Introduction:

Heat treatment takes place under metal operating procedures that sometimes also alter chemical physical characteristics. In the production of many other products, such as glass, heat treatments are also used. Heat treatment includes heating o rcooling to obtain a required outcome such as hardening or softening of a material, usually at extreme temperatures. Techniques for heat treatment include annealing.

Interpretation Introduction

(b)

Interpretation:

The tensile strength and yield strength obtained using 1080 steel under heat treatment process needs to be determined.

Concept Introduction:

Heat treatment includes heating or cooling to obtain a required outcome such as hardening or softening of a material, usually at extreme temperatures. Techniques for heat treatment include annealing Heat treatment takes place under metal operating procedures that sometimes also alter chemical physical characteristics. In the production of many other products, such as glass, heat treatments are also used.

Interpretation Introduction

(c)

Interpretation:

During the normalisation of 1050 steel, find the yield strength, tensile strength and % elongation needs to be determined.
