Materials - 2023 entry

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.

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 is a constituent module of one or more degree programmes which are accredited by a professional engineering institution under licence from the Engineering Council. The learning outcomes for this module have been mapped to the output standards required for an accredited programme, as listed in the current version of the Engineering Council’s ‘Accreditation of Higher Education Programmes’ document (AHEP-V3).

This module contrinutes to learning outcomes: SM1p, SM1m, SM3p, SM3m, SM4m, SM6m, EA4p, EA4m, EP2p, EP2m, EP3p, EP3m, G1p, G1m
