(a) Determine whether this metal’s crystal structure is FCC, BCC, or neither FCC or BCC, and explain the reason for your choice. (b) If the crystal structure is either BCC or FCC, identify which of the metals in the table gives this diffraction pattern. Justify your decision. WebWhen it crystallizes at low temperatures (room temperature), the hexagonal close-packed (HCP) structure of alpha titanium is formed. While it crystallizes at high temperatures, the body-centered cubic (BCC) structure of beta titanium is formed. The complete transformation from one to another crystal structure is called allotropic transformation.
