Materials for Engineering Flashcards
investigates the relationships that exist between the structure and properties of materials
Materials Science
Involves designing or engineering the structure of a material to produce a predetermined set of properties
Materials Engineering
The role is to develop or synthesize new materials
Materials Scientist
Create new products using existing materials
Materials Engineering
develops systems or techniques in the processing of materials
Materials Engineering
Refers to the arrangement of a materials internal components
Structure
4 types of structures
Subatomic, Atomic, Microstructure, Macrostructure
Involves electrons and their interaction with the nuclei
Subatomic
Organization of atoms or molecules relative to one another
Atomic
Group of atoms that can be seen by a microscope
Microstructure
Structural elements that can be seen by the eye
Macrostructure
Criteria for the Selection of Materials
- in-service condition
- deterioration of material properties
- Economics (Quality vs Cost)
While in use, a material is subjected to an external stimulus that results in a particular response
Material Property
Six Important Material Properties
Mechanical
Electrical
Thermal
Magnetic
Optical
Deteriorative (Chemical)
Express the relationship of deformation to the applied load or force
Mechanical Properties
Express the response of a material to an electric field
Electrical Properties
Express the response of a material to heat
Thermal Properties
Express the response to a magnetic field
Magnetic Properties
Response of the material to electromagnetic or light radiation
Optical Properties
Refers to the chemical reactivity of the material
Deteriorative (Chemical) Properties
Four Components Involved in the Science and Engineering of Materials
Processing
Structure
Properties
Performance
