With increase in annealing temperature, the following defect density decreases?
Correct answer: C. All of these
- A. Vacancy
- B. Dislocation
- C. All of these
- D. Grain boundary
Explanation
Annealing allows vacancies to diffuse, dislocations to recover, and grains to grow, reducing the densities of these defects in the material. Thus all the listed defect densities can decrease during suitable annealing.
