Description
2.1
Aims
The aims of this module are to:


2.2
develop a basic understanding of the properties of materials
and hence provide a sound rationale for selection and use of materials in
engineering.
Objectives (planned learning outcomes)
Knowledge and understanding
Having successfully completed the module, you will be able to demonstrate knowledge
and understanding of:


the physical origins of properties of materials and their control.
the ways in which properties of materials govern their selection in engineering
applications.
Intellectual skills
Having successfully completed the module, you will be able to:






demonstrate how defects in atomic structure affect mechanical properties
relate the kinetics of a number of apparently different materials processes to the
same underlying process (diffusion)
explain how strengthening mechanisms occur on the microstructural scale and how
this is related to the bulk mechanical properties we require in engineering structures
apply the use of phase diagrams to explain the development of microstructure and
hence how alloys are designed
analyse failure problems and apply the correct fracture mechanics approach
show how non-metallic bonding leads to very different properties (e.g. ceramics
and polymers)
Practical skills [where appropriate]
Having successfully completed the module, you will be able to:


conduct tensile and fracture toughness tests
assess fractography
General transferable (key) skills
Having successfully completed the module, you will be able to:


solve problems (i.e. link appropriate analytical approaches to engineering
problems)
discuss problem solving approaches in small groups
2.3

the Periodic table; bonding and interatomic forces; the structure of crystalline solids; basic structures, unit
cells; holes and lattices; imperfections in solids; point, linear, planar and volume defects; diffusion.
Mechanical properties (3 lectures): Stress and strain; elasticity; tensile properties; hardness;
strengthening mechanisms; recovery, recrystallisation and grain growth.
Microstructures and their control (5 lectures) : Phase diagrams; thermal processing; precipitation
hardening
Failure of metals (3 lectures) : Failure; fracture, brittle and ductile failure; impact and fracture toughness;
fatigue; creep.
Non metallic materials and their properties (4 lectures): Ceramics and glasses; main classes, properties
and uses; polymers; basic structures and bonding; polymerisation; cross linking; thermoplastics and
thermosets; composites; main classes, properties and uses.

24 lectures (two 45 minute sessions per week) which develop the themes described in this
module. Skeleton notes (orange book) are given out at the start of the course, which
means you only have to note down the key points during the lecture, but still have a full
set of notes to work from.
2 supervised examples classes (with web-based materials) these are based in computing
clusters and last for ~ 2.5-3 hours. You will work through the problems in your green
course-book and have access to a detailed web package, incorporating additional material
that supplements the lectures, including animations and self-test multiple choice questions
(MCQs). An academic supervisor and postgraduate tutor-demonstrators will be on hand
throughout the session to discuss the problems set out in your green workbook and to mark
and correct your work. You must be signed out by one of these members of staff to confirm
you have attended and satisfactorily completed these classes as part of your formal
coursework requirement
1 laboratory class on mechanical testing (including MCQ assessment). You will carry out a
number of mechanical tests, pool your results and write up the lab as a class in your green
course-book during the laboratory session (~ 2.5-3 hours). After a class-room discussion of
the results (led by an academic supervisor) there will be a closed notes 15 minute MCQ test,
which will be marked in the class and goes towards your formal coursework requirement.
This together with the supervised examples classes will define 10% of your overall mark
5 supervisions (small group work in groups of 12-20). There is a set of supervision
questions on each of the five main sections of the course in the green coursework book.
You should attempt each supervision sheet before the relevant supervision, and the
questions and solutions to them will be discussed with the whole class, led by an academic
supervisor
Learning activities include
Web-based self-paced MCQ throughout course
Self-study of web-based materials after introduction in supervised examples classes
Access to past paper exam question bank

Feedback and student support during module study (formative assessment)
A series of supervision problems are attempted in small groups, and the solutions are discussed with the
supervisor. (MCQs) are available electronically from a pool of quizzes on all aspects of the course, and
allow you to independently test and retest your own performance. Supervised examples classes using
web-based materials (e.g. animations) and problems are worked through with tutors and the students’
working is checked/corrected in their course-book. The formal MCQ at the end of the laboratory is
marked at the end of the session giving direct feedback. Past papers and some model answers are
available on the web site
2.7
Relationship between the teaching, learning and assessment methods and
the planned learning outcomes
The laboratory sessions, supervision classes and examples classes are intended to strengthen
understanding and application of the lecture material. The examinations test understanding of the
underlying concepts and links between the five main subject areas. Examination questions are structured
to test problem solving skills and application of knowledge.
