Relationship between structures and properties of materials

Structure: arrangement of internal component



Properties: kind and magnitude of response to a specific imposed stimulus
Designing or engineering the structure of a material to produce a predetermined set of properties

Processing - affects structure
Performance - affected by its properties
single-crystal
Combination of metallic elements
Large number of nonlocalized electrons
Conductors of electricity and heat
Strong but deformable
Metal and non-metal elements
Insulators
More resistant to high temps and harsh environments
Hard but brittle
Usually organic compounds
Carbon, hydrogen, non-metals
Low density and flexible
Consist of more than one material type
Display a combination of the best characteristics of each of the component materials
Shape memory alloy - revert back to original shape with change in temperature
Piezoelectric ceramics - expand and contract in response to applied electrical field
Magnetostrictive materials - responsive to magnetic field
Electrorheological/magnetorheological fluids - change viscosity with application of electric/magnetic field
Structural entities that are on the order of a nanometer, usually less than 100nm
Microscopic
Atomic Level
