Calculate the ductility of this steel alloy in %EL.

This image displays a stress-strain curve, which is an essential graphical representation in materials science for analyzing how a material deforms under various stresses. ### Graph Explanation **Main Graph:** - **Axes:** - The x-axis represents strain, ranging from 0.000 to 0.080. - The left y-axis indicates stress in megapascals (MPa), ranging from 0 to 2000 MPa. - The right y-axis shows stress in thousands of pounds per square inch (10^3 psi), ranging from 0 to 300. - **Curve:** - The curve begins steeply at the origin, indicating elastic deformation where stress and strain are proportional. - As the curve starts to flatten, it signifies the yield point and the transition to plastic deformation. - The curve eventually reaches a peak and may decline slightly, suggesting necking or material failure. **Inset Graph:** - **Axes:** - The x-axis spans a smaller strain range from 0.000 to 0.015. - The y-axis covers stress in both MPa and 10^3 psi, matching the main graph. - **Curve:** - This inset graph provides a magnified view of the initial linear portion of the stress-strain curve, emphasizing the elastic behavior of the material. ### Educational Importance Understanding the stress-strain relationship is crucial for predicting material behavior, evaluating mechanical properties, and designing materials for specific engineering applications. This curve helps engineers and scientists determine the elastic limit, yield strength, ultimate tensile strength, and ductility of materials.
