Overview:

This module presents students with the major theoretical concepts associated with materials science, such as bonding, atomic and molecular structure, phase equilibria, crystallography, and dislocation theory, so that a strong understanding of the relationship between structure and properties in materials can be developed. It also introduces and presents the basic theory associated with the mechanical behaviour of engineering materials when under load, both in the elastic and plastic regimes, as appropriate to the material.

The module also presents the materials science theory within a real-world context, with a particular emphasis on the manufacturing methods that are employed to turn basic materials into components and products. Through this study it will hopefully become apparent that the properties of materials are strongly determined by the structure of materials (on levels ranging from the nano to the macro scale) and that such structure is, in turn, itself strongly influenced by the manufacturing methods utilized. It is through manufacturing methodology that engineers have the greatest ability to alter and optimise materials properties such as strength and toughness, stiffness and even corrosion resistance.

Topics covered:

• Basic definitions and fundamental properties important to the mechanical engineer
• Bonding
• Solids
• Alloys
• Introduction to Steel
• Introduction to Polymers
• Introduction to crystallography
• Deformation
• Increasing strength: mechanisms of strengthening of materials and the role of dislocation movement
• Review and summary of major manufacturing processes

Learning outcomes:

Upon completion of this module students will gain:

• A basic understanding of the level of structure within materials right down to the atomic level.
• A sound knowledge and understanding of the structure-property relationships present in materials.
• An understanding of the categories and importance of mechanical properties.
• A basic knowledge of manufacturing methods and their use in modern systems and components and which methods are appropriate to which materials.
