Question
**Text:** Which curve shown below (A or B) is for a BCC metal and why? **Graph Explanation:** The graph is a plot of "Impact Energy" on the y-axis against "Temperature" on the x-axis. - **Curve A** (green): This curve maintains a relatively high level of impact energy across the temperature range, indicating a generally consistent ductility. - **Curve B** (magenta): This curve shows a significant increase in impact energy as the temperature rises, transitioning from brittle to more ductile behavior. It features a notable "Ductile-to-brittle transition temperature," marked in blue. **Key Features:** - **Brittle Region:** For Curve B, at lower temperatures, the material exhibits brittle behavior, shown by low impact energy values. - **More Ductile Region:** As the temperature increases, Curve B indicates that the material becomes more ductile, shown by higher impact energy values. - **Transition Temperature:** There is a specific temperature at which the transition from brittle to ductile occurs, highlighted for Curve B. **Explanation Context:** BCC metals typically exhibit a ductile-to-brittle transition, making Curve B representative of such behavior. Curve A, with no significant transition, likely represents a different crystal structure.
