What is the crystalline structure of titanium at room temperature?Group of answer choicesFCCHCPBCCSC

The crystalline structure of titanium at room temperature is predominantly HCP (Hexagonal Close-Packed).

Explanation:

Titanium has a unique allotropy, meaning it can exist in different structural forms at varying temperatures. At room temperature, titanium adopts the HCP structure, which consists of layers of atoms arranged in a hexagonal pattern. This structure is characterized by a high packing efficiency which allows for both strength and ductility, making titanium an ideal material for various applications, particularly in aerospace and medical contexts.

As the temperature increases, titanium transitions from the HCP structure to a body-centered cubic (BCC) structure at around 882°C. This high-temperature phase stabilizes at elevated temperatures and allows for different mechanical properties. The favorable properties of HCP titanium at room temperature make it particularly useful where high strength-to-weight ratios are critical.
