Materials having _____________ lattice structure are usually most ductile?
Correct answer: A. FCC
- A. FCC
- B. BCC
- C. HCP
- D. Cubic
Explanation
FCC metals have many closely packed slip systems, allowing dislocations to move readily and producing high ductility. HCP metals have limited slip systems, while BCC metals are generally less ductile at ordinary temperatures.
