Mild steel has _______________ crystal lattice structure?
Correct answer: C. Body centred cubic (bcc)
- A. Face centred cubic (fcc)
- B. Orthorhombic
- C. Body centred cubic (bcc)
- D. Cubic
Explanation
At ordinary temperatures, mild steel consists mainly of ferrite, whose iron atoms have a body-centred cubic lattice. The face-centred cubic structure occurs in austenite at higher temperatures.
