SESG6042 Materials for Transport Applications

Module Overview

This module considers metallic alloys with special reference to applications in transport applications. The main materials considered are aluminium, titanium and nickel based alloys, and steel. Also metal based composites, and high temperature materials such as intermetallics and ceramics are considered. Examples of applications are drawn from aerospace, automotive and marine industries. The microstructural development of the materials is considered in detail, and the use of "microstructural engineering" in materials design and selection explored.

Learning and Teaching

Teaching and learning methods

Lectures which develop the themes described in this module. Notes are given out at the start of the course, which means you only have to note down some key points during the lecture, but still have a full set of notes to work from. The teaching is supported by web-based teaching ( This provides additional teaching material in the form of links to relevant websites, (links to) relevant technical papers, and quizzes on selected chapters with feedback. Learning activities include • Access to exam question bank. • Online Quizzes and questions on Blackboard, with instantaneous on-line feedback and feedback in lectures where common mistakes are discussed. • Revision questions set by lecturers which are intended for (small group) self-study.
