Question Paper
1. Choose the correct answer from the given four alternatives.
If a material recovers its original dimensions, when the load is removed, it is known as
Brittle
Elastic
Plastic
Annealed
Any process of heating and cooling steel that produces a rounded or globular form of carbide is known as
Normalizing
Ultra-hardening
Drawing
Spheroidizing
The dominant elements in shock resisting tool steel are
Chromium, tungsten
Carbon, iron
Cobalt, nickel
Aluminium, copper
In powder metallurgy, the process of heating the cold pressed metal powder is known as
Sintering
Granulation
Deposition
Precipitation

Slow heating
Rapid heating
Slow cooling
Rapid cooling
State the difference between steel and cast-iron with respect to their composition, properties and applications.
State the reasons why white cast-iron is more brittle than grey cast-iron.
Name two alloying elements other than carbon, commonly employed in steel, and also explain how they influence the properties of steel.
Describe the ranges of major alloying elements for low, medium, and high carbon steels. Give two applications for each range.
Discuss the advantages of aluminium alloys over ferrous alloys.
Distinguish clearly between hardness and hardenability. Explain a method of measuring the hardenability of steel.
Differentiate between normalizing and annealing, in terms of the process and nature of the product.
