The temperature at which new grains are formed in the metal is called the ______________ temperature?
Correct answer: B. Recrystallisation
- A. Eutectic
- B. Recrystallisation
- C. Upper critical
- D. Lower critical
Explanation
Recrystallisation is the formation of new, strain-free grains when a cold-worked metal is heated sufficiently. Eutectic and critical temperatures describe phase transformations rather than grain renewal.
