Chapter_3에 대한 보고서 자료입니다.

목차

• How do atoms assemble into solid structures?
(for now, focus on metals)
How does the density of a material depend on
its structure?

• When do material properties vary with the
sample (i.e., part) orientation?

본문내용

Metallic Crystal Structure
-• Tend to be densely packed.
• Reasons for dense packing:
- Typically, only one element is present, so all atomic
radii are the same.
- Metallic bonding is not directional.
- Nearest neighbor distances tend to be small in
order to lower bond energy.
- Electron cloud shields cores from each
