List some advantages of metals
High tensile & compressive strength, high stiffness, ductile, recyclable
1 of 14
List some disadvantages of metals
High cost, potential corrosion risk, vulnerable to fire
2 of 14
Manufacturing process of metals?
Extracted, heated to seperate from oxides, then metal is tapped off and reheated to shape
3 of 14
A negative characteristic of metals?
corrosion: rapid surface oxidation
4 of 14
Briefly explain metallic bonding?
Free elections move around the area
5 of 14
What are properties of HCP crystal forms?
Hexagonal close packed crystals
6 of 14
What are properties of FCC crystal forms?
An atom in each corner, and one central to each face
7 of 14
What are POINT IMPERFECTIONS?
They occur as the result of a vacancy or impurity within the crystal lattice
8 of 14
Forcing crstal bonds to move past the yield point does what?
Causes a dislocation of the crystal, making it brittle BUT STRONGER
9 of 14
What does rapidly cooling metals produce?
A finer grained strucuture
