Q
Crystalline
A
Atoms arranged in a regular repeating pattern
1
Q
Example of composite
A
Concrete - strong under compression, brittle under tension
Steel rods added to increase tensile strength
2
Q
Why are metals ductile?
A
The ions within the lattice can move
3
Q
Polycrystalline
A
When there are many regions or grains of crystalline structure.
Oriented in different directions.
4
Q
What is work hardening?
A
As metallic ions are dislocated, they begin to lose their general structure and lattice plains entangle so the metal loses its malleability
