IET 170 Final Exam questions n
answers graded A+
Plasticity - correct answer ✔✔ The ability to flow as solids without deterioration or their
properties
Hot Working - correct answer ✔✔ The plastic deformation of metals at a temperature above
the recrystallization temperature.
Cold working - correct answer ✔✔ the plastic deformation of metals below the recrystallization
temperature. Usually performed at room temperature.
Recrystallization - correct answer ✔✔ If the metal first experiences a sufficient amount of
deformation, the distorted structure will be rapidly replaced by new straight-free grains.
Formability - correct answer ✔✔ ability of material to be deformed
Bulk deformation processes - correct answer ✔✔ processes in which the thickness or cross
sections are reduced or shapes are significantly changed.
Examples of bulk deformation processes - correct answer ✔✔ rolling
forging
extrusion
piercing
cold forming
other squeezing processes
