Austempering process results in the formation of ________________ structure ?
Correct answer: B. Bainitic
- A. Martensitic
- B. Bainitic
- C. Carburised
- D. Stressed
Explanation
Austempering involves quenching steel to the bainite range and holding it there until transformation is complete. The resulting structure is bainite, not martensite, which forms when the steel is quenched below the martensite-start temperature.
