Material Science is the study of investigating the relationship that exists between the structures and properties of materials.
Ages of Material Science
1. Stone Age
2. Bronze Age
3. Iron Age
Classification of Materials
1. Metals – are combination of metallic materials
2. Polymers – materials made of plastic and rubber
3. Ceramics – compound between metallic and nonmetallic
4. Composite – engineered materials composed of different material type
5. Semiconductor – has intermediate electrical properties
6. Biomaterials – materials that can be used to a human body
Properties of Material
1. Mechanical Properties
2. Electrical and Magnetism Properties
3. Optical Properties
4. Thermal Properties
5. Deteriorative Properties
Properties of Materials based on Engineering
1. STRENGTH - The ability of a material to stand up to forces being applied without it bending, breaking, shattering or deforming in any way.
2. ELASTICITY - The ability of a material to absorb force and flex in different directions, returning to its original position.
3. PLASTICITY - The ability of a material to be change in shape permanently.
4. DUCTILITY - The ability of a material to change shape (deform) usually by stretching along its length.
5. TENSILE STRENGTH - The ability of a material to stretch without breaking or snapping.
6. MALLEABILITY - The ability of a material to be reshaped in all directions without cracking
7. TOUGHNESS - A characteristic of a material that does not break or shatter when receiving a blow or under a sudden shock.
8. HARDNESS - The ability of a material to resist scratching, wear and tear and indentation.
9. CONDUCTIVITY - The ability of a material to conduct electricity.
