ES195-15 Materials for Engineering
This module is about equipping students with the basic skills and knowledge needed to conduct a substantiated selection process for the materials and manufacturing processes that are needed to make a component. Selecting the wrong material or manufacturing process can be as bad as any other poor decision when designing engineering systems - at best this will result in a non-competetive product and at worst can lead to environmental issue or the catasptrophic failure of the component.
To a first approximation materials are chosen empirically by looking what materials are common for the application being considered. A better selection then is to consider what properties are required an match these to materials/material types.
Deeper understanding then derives from understanding how these properties are moderated. The first level of this is by understanding what microstructures a material is capable of, which can have a huge impact on the performance and lifespan of the material. The second is the influence of treatment processes on these structures. At the base level sits the immutable limitations to material behaviour which are derived from the atoms and interatomic bonds present in the material.
The module will begin by describing the fundamental way by which material selection integrates into the rest of the engineering design process. As the term progresses the student's skill in materials selection will be strenghtened with the help of CAE tools and the knowledge of materials science is extended so that they can make a more sophiosticated case for selecting one material over another for a particular application. This extension of knowledge is also a progressive dive down to the atomic level of the underlying science so that the improvement in materials selection skills is complemented by an increase in knowledge and understanding of materials.
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
The syllabus is made of six main sections: Selection, Applications, Properties, Microstructures, Processing, Chemistry. There is a general progression from Selection to Chemistry during the module, so that the module starts at the simple end of the selection process, i.e., common sense and stereotypical material use, and then explores the layers of understanding between this simple approach and the constitutent atoms and bonds that make up a material. The objective is to equip the student with the "starter pack" of skills and knowledge required to look at materials and process selection as a functional task. This functional task starts with a set of requirements on the component which can be expressed as a set of materials property-based performance indices which can be used to highlight without prejudice what materials are capable of meeting those requirements. With this broader outlook on materials and their related manufacturing processes an engineer can better explore the balances between pragmatism and innovation, and between financial profit and environmental impact.
By the end of the module, students should be able to:
- Select an appropriate engineering material and manufacturing process for a given design.
- Link the performance of engineered products to the complex interactions between material, manufacturing process and design.
- Explain how the structure of engineering materials affect the properties through the structure property relationship.
- Describe how structures of materials can be manipulated to enhance the properties of materials.
- Distinguish the main classes of engineering materials and the underlying materials science that determines their properties and their applications.
- Evaluate the life cycle environmental impacts related to the material and process design choices.
