Some Basic Principles Of Organic Chemistry Question 225
Question: Annealing of steel is the process of heating steel
Options:
A) to a bright red hot and then cooling it slowly
B) to a bright red hot and then cooling it suddenly
C) to a temperature much below redness and cooling it slowly
D) none of the above
Show Answer
Answer:
Correct Answer: A
Solution:
During the annealing process, the metal is heated to a specific temperature.
Where recrystallization can occur.
At this stage, any defects caused by deformation of the metal are repaired.
The metal is held at the temperature for a fixed period, then cooled down to room temperature very slowly.
