1. What is metallurgy primarily concerned with?
A. Electrical circuit design
B. Chemical fertilizer production
C. The study and processing of metals and alloys
D. Textile manufacturing
Rationale: Metallurgy focuses on the extraction, processing,
properties, and performance of metals and alloys.
2. Which metal is the primary component of steel?
A. Aluminum
B. Copper
C. Nickel
D. Iron
Rationale: Steel is an alloy primarily composed of iron and
carbon.
3. What is an alloy?
,A. A pure metallic element
B. A ceramic material
C. A combination of two or more elements, at least one being a
metal
D. A heat-treatment process
Rationale: Alloys are created to improve properties such as
strength, hardness, and corrosion resistance.
4. Which element is commonly added to steel to increase
hardness?
A. Oxygen
B. Hydrogen
C. Carbon
D. Helium
Rationale: Carbon significantly increases the hardness and
strength of steel.
5. What property describes a metal's ability to be hammered
into sheets?
A. Ductility
B. Brittleness
C. Toughness
D. Malleability
,Rationale: Malleability refers to deformation under
compression without fracture.
6. Which property describes a material's ability to stretch into
wire?
A. Hardness
B. Elasticity
C. Ductility
D. Conductivity
Rationale: Ductile materials can be drawn into thin wires.
7. Which test measures resistance to indentation?
A. Tensile test
B. Impact test
C. Bend test
D. Hardness test
Rationale: Hardness testing evaluates resistance to localized
plastic deformation.
8. Which hardness test uses a diamond cone indenter?
A. Brinell
B. Vickers only
, C. Rockwell C
D. Charpy
Rationale: The Rockwell C scale uses a diamond cone known as
a Brale indenter.
9. What is the purpose of heat treatment?
A. To increase metal weight
B. To reduce metal value
C. To alter mechanical properties through controlled heating
and cooling
D. To remove all alloying elements
Rationale: Heat treatment improves hardness, toughness,
machinability, and strength.
10. Annealing is primarily used to:
A. Harden steel
B. Soften metal and relieve internal stresses
C. Increase brittleness
D. Promote corrosion
Rationale: Annealing improves ductility and machinability.
11. Quenching is generally performed to:
