The aim of the module is to introduce the range of materials used in engineering applications along with some basic selection rules for determining the appropriate materials for a given application. The module also introduces fundamental science that determines the properties of materials, such as bonding types and atomic / molecular structures.
Syllabus:
Classification of materials into key groups
Identification of key mechanical and physical properties affecting materials selection
Concept of materials selection charts
Fundamental science
bonding between atoms
structure of engineering materials, packing in metals and ceramics, molecular chains in polymers)
relation between bonding type and structure to mechanical properties
Definition and measurement of key mechanical properties
Young's modulus
Strength
Hardness
Toughness
Definition and measurement of whole life issues
Corrosion (including galvanic corrosion)
Fatigue
Cost / availability
Recycling
Appreciation that the microstructure affects the properties of metals using steel as an example
Selection of materials for a given, simple, application
