Steels used in car bodies.

1. Identify and explain the selection of the specific material used for the specific
application.
2. Find the composition of the material.
3. Discuss the atomic bonding and structure in the material.
4. Discuss its phase diagram.
5. Predict its microstructure, strengthening mechanisms, and its resulting mechanical
properties, including yield strength, ultimate tensile strength, and elastic modulus
from engineering plots of σ−ε.
6. Discuss other needed properties for the material in addition to the mechanical
characteristics which depend on the selected application, e.g. thermal conductivity,
bio-compatibility, corrosion resistance, etc. Identify how you achieve/optimize these
property requirements.
7. Estimate its impact on society, including specifically occupational safety and health,
global availabilities of commodity material, recycling approaches, energy savings
and others.
