DESCRIPTION - summary of the module content

This module builds on the materials science content of the core course and equips you with a deeper understanding of the deformation, strengthening and failure of materials, including surface processes. You will learn about failed components and the processes and techniques of Materials analysis.. The module content also emphasises the interrelationship between mathematical models of materials and their mechanical properties and provides material in support of the subsequent design modules.

AIMS - intentions of the module

By the end of this module, you will demonstrate aptititude in using phase diagrams, TTT-diagrams and micrographs to predict the composition and properties of metals and alloys. You will also be capable of applying the concept of dislocations to quantitatively describe plasticity, strengthening and creep, and utilising Weibull statistics to predict the failure of ceramics.

 

Furthermore, you will show competence in adopting advanced materials selection algorithms to support design, and will understand the different types of friction and wear and extract friction coefficients from typical graphs. Moreover, you will comprehend different types of surface treatments (including laser, nitriding and carburising) and have the ability to establish links between principles and applications.

 

In addition, you will appreciate the physical principle underlying material characterisation techniques (XRD, SEM, TEM, Thermal, Gas sorption) and interpret results. Finally, you will be able to identify which characterisation technique is best adapted to a given materials/situation and instruct a technician to this effect
 
 
This module covers Specific Learning Outcomes in Engineering, which apply to accredited programmes at Bachelors/MEng/Masters level. These contribute to the  educational requirements for CEng registration (as defined under the UK Standard for Professional Engineering Competence – UK-SPEC).
 
 
 
This module correlates to references U2, E3, MU2, MU4, MP1 and MP2. These references are indices of the specific learning outcomes expected of Bachelors/MEng/Masters candidates set out in UK-SPEC, codified with reference to systems used by professional accrediting institutions. A full list of the standards can be found on the Engineering Council's website, at http://www.engc.org.uk

RE-ASSESSMENT NOTES

If a module is normally assessed entirely by coursework, all referred/deferred assessments will normally be by assignment.

 

If a module is normally assessed by examination or examination plus coursework, referred and deferred assessment will normally be by examination. For referrals, only the examination will count, a mark of 40% being awarded if the examination is passed. For deferrals, candidates will be awarded the higher of the deferred examination mark or the deferred examination mark combined with the original coursework mark.
