Question

Chapter 5, Problem 5.1Q

(a)

To determine

The characteristics of an alloy.

(a)

Expert Solution

Explanation of Solution

The characteristics of an alloy are as follows.

An alloy is a compound having two or more chemical elements, among them at least one is a metal.
They are used to enhance the properties of pure metals.
They could also form intermetallic compounds.
The alloys are used to make a metal harder than before.

(b)

To determine

The characteristics of pearlite.

(b)

Expert Solution

Explanation of Solution

The characteristics of pearlite are as follows.

It has an alternate layer of ferrite and cementite in its structure.
It has properties between soft and ductile or hard and brittle.
Strength of steel is formulated by the spacing of the lamellae.
It can also be drawn into thin wires.

(c)

To determine

The characteristics of austenite.

(c)

Expert Solution

Explanation of Solution

Austenite is a form of steel used as a highly graded stainless steel. Some of the characteristics of austenite is as follows:

It is an allotropic form of iron having an FCC crystal structure.
This structure has a solid solubility of up to 2.11 %.
It possesses good formability, as it becomes ductile at elevated temperature.
Due its FCC structure it can dissolve nickel and manganese in it.
Austenitic steel is non-magnetic at high temperatures.

(d)

To determine

The characteristics of martensite.

(d)

Expert Solution

Explanation of Solution

The characteristics of martensite are as follows.

It is a tetragonal form of iron.
It has the carbon present in the interstitial position thus helps to gives higher strength.
It is formed during the process of quenching.
The martensite form of iron is very hard and brittle in nature.

(e)

To determine

The characteristics of cementite.

(e)

Expert Solution

Explanation of Solution

The characteristics of cementite are as follows.

It has 100% of iron carbide with carbon content of 6.67 % and is also known as carbide.
It is very hard and brittle in nature.
This iron carbide has an orthorhombic crystal structure.
It can be used with different alloys like chromium and molybdenum to enhance their properties.
