In hot working, plastic deformation operations are often carried out at temperatures above the ______ temperature.
A. melting
B. recrystallization
C. room
D. cold working
Answer:B
In hot working, plastic deformation operations are often carried out at temperatures above the ______ temperature.
A. melting B. recrystallization C. room D. cold working
Explanation: Plastic deformation operations are often carried out at temperatures above the recrystallization temperature in a process termed hot working. The material remains relatively soft and ductile during deformation because it does not strain harden, and thus large deformations are possible.
