Chapter 8, Problem 8.68P

Interpretation Introduction

(a)

Interpretation:

A graphical representation of yield strength and grain size various annealing temperature for cartridge brass needs to be determined.

Concept Introduction:

Cartridge brass consists of 70 % copper and 30 % Zn. Which is cold rolled and annealed for one hour graph is plotted for different annealing temperature.

Interpretation Introduction

(b)

Interpretation:

The various stages of annealing at each temperature needs to be stated.

Concept Introduction:

Annealing is done to reduce cold working effects. Annealing is done at a relatively low temperature as compared to other heat treatment. It generally softens the metals.
