,Introduction
, Materials Science and Materials Engineering
Materials science: relationships between the structures and
properties
Materials engineering : designing or engineering the structure to
get predetermined (desired) properties
Structure: arrangements of internal components
Subatomic structure
Atomic structure
Microscopic structure
Macroscopic structure
, Property: is a material inherited characteristic in terms of the kind
and magnitude of response to a specific stimulus ( in
general materials’ properties are independent of shape
and size).
Properties of solid materials are categorized:
1. Mechanical
2. Electrical
3. Thermal
4. Magnetic
5. Optical
6. Deteriorative
