B. 600°C to 900°C
C. 900°C to 1400°C
D. 1400°C to 1530°C
Answer: Option D
Solution(By Examveda Team)
As molten iron cools down, it solidifies at 1,538°C (2,800°F) into its δ allotrope, which has a body-centered cubic (BCC) crystal structure. δ-iron can dissolve as much as 0.08% of carbon by mass at 1,475°C.This Question Belongs to Mechanical Engineering >> Engineering Materials
