SESG6044 Microstructural and Surface Characterisation

Module Overview

This module on microstructural analysis and surface characterisation of materials and components considers Surface Profilometry, transmission electron microscopy (TEM), scanning electron microscopy (SEM), optical microscopy, diffraction techiniques, energy dispersive spectroscopy (EDX), and a range of other techniques. For each technique, the aspects covered include: relevant theoretical background, sample preparation, equipment capabilities and limitation of the techniques. Examples of usage are drawn mainly from materials used in aerospace, automotive and marine industries. As part of the module either a laboratory involving hands on use of the SEM and/or TEM can be taken or, alternatively, a coursework on the interpretation of microstructural analysis and surface characterisation from literature can be elected.

Aims and Objectives

Module Aims

- To teach students the main experimental techniques used for characterising the nano- and microstructure of materials and the surfaces of materials that have applications in the engineering sciences. - To further develop the understanding of the relations between of nano- and microstructure of materials and their properties. - To provide students with a sound understanding of the use of analytical instrumentation for the materials structures, crystallography and chemical information.

Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • The application of Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), optical microscopy, Electron Backscatter Diffraction (EBSD), Energy Dispersive X-ray Analysis (EDX) and surface profilometry techniques to engineering materials.
  • Crystallography of crystalline materials
Subject Specific Intellectual and Research Skills

Having successfully completed this module you will be able to:

  • Appreciate the capabilities of different analysis techniques for characterising the microstructure and surface of materials and components.
  • Analyse (parts of) technical reports and scientific papers that relate to microstructure and surface analysis.
  • Make an assessment as to whether available data constitutes a definite identification of a phase / structure
  • Depending on the selection of final assignment either to be able to operate an electron microscope or to analyse academic and technical literature containing electron microscopy and crystallography data.
Transferable and Generic Skills

Having successfully completed this module you will be able to:

  • Contribute materials microstructure and surface characterisation knowledge as part of teams in most engineering industries.

Learning and Teaching

Teaching and learning methods

Teaching methods include - The module is predominantly self-paced. The module starts with a group meeting to introduce the module followed by 3 progress meetings. - The main component of the teaching is web-based, through the 'Blackboard' package (http://blackboard.soton.ac.uk/). This provides the main text of the course, with additional teaching material in the form of links to relevant websites, and (links to) relevant research papers. - For Section 11, students will do a supervised laboratory with access to electron microscopes. - 2 revision lectures in the weeks prior to the exam to revise and review the material in the course. Learning activities include - Access to exam question bank. - Revision questions set by lecturers which are intended for (small group) self-study.

Assessment

Assessment Strategy

Notes: External repeat students will take section 12 - XPS, XRD, FIB and scientific report analysis. Feedback includes: - Quizzes on Blackboard which provide instant feedback. - Return of marked coursework with written feedback on each coursework within 15 working days of hand in. - General discussion on each e-mailed questions during the timetabled sessions. - Revision sessions in which past exam questions are discussed based on e-mailed requests from students. - E-mailed responses or additional tutorials by lecturer to e-mailed individual questions
