Which type of metal forming process involves compressive forces applied between two rotating rolls to reduce thickness?
Drawing
Rolling
Extruding
Forging
During hot working, the metal is deformed:
Below its recrystallization temperature
Above its recrystallization temperature
At sub-zero temperatures
Only after cold rolling
Which of the following is an advantage of cold working?
Produces residual stresses
Requires less force and power
Improves surface finish and dimensional accuracy
Reduces hardness and strength
In heat treatment, quenching immediately after heating generally results in:
Increased brittleness and hardness
Decreased hardness and strength
Improved ductility
No change in grain structure
Which of the following metals is commonly annealed to improve ductility before forming?
Aluminum
Cast iron
Stainless steel
Titanium
In aircraft welding, the term “fusion zone” refers to:
The area that remains unaffected by heat
The region where base metals melt and combine
The section cooled by shielding gas
The outer layer formed after heat treatment
Which of the following welding methods does not require filler metal?
TIG welding
MIG welding
The primary purpose of normalizing a steel component is to:
Increase internal stresses
Refine grain structure and improve toughness
Decrease hardness
Harden the outer surface
When laying out a sheet metal bend, “bend deduction” is defined as:
The length added to compensate for stretching
The amount subtracted from total flange lengths to get the flat pattern
The line representing the bend center
The radius between the inside surfaces of the bend
The process of joining dissimilar metals using a filler metal below 450°C is called:
Brazing
Welding
Hard soldering
Sintering
