MATS64301 15 Semester 1 Postgraduate Taught Level 6 Phillipp Frankel Unit coordinator Department of Materials 1 FHEQ level (Framework for Higher Education Qualifications) ' Masters/Integrated Masters P4 ' European Credit Transfer & Accumulation System Rating : 7.5 <p>Many applications of advanced materials are highly tailored to give enhanced structural or functional properties. These properties are controlled by both the intrinsic material properties and the microstructure of the material. An understanding of the relationship between the properties of a material and its microstructure is important in the selection of materials for a given application or the design of a material to achieve a specific function. The processing routes are used to create these microstructures that provide the desired properties. The objective of this course is to give an overview of the essential concepts underpinning materials science and engineering.</p><p>This unit will describe a number of materials manufacturing methods and discuss how these influence the resulting microstructures using examples from metals and ceramics. For each material type, the importance of defects in controlling properties will be discussed with examples. These defects will then be linked to the processing routes and lead on to understanding the different failure mechanisms illustrated with examples.</p> <p>Many applications of advanced materials are highly tailored to give enhanced structural or functional properties.

Identify and justify when you would use the different methods.</li><li>Describe how the following act to strengthen an alloy: precipitate hardening, solid solution strengthening, grain size refinement, creation of single crystal/crystallographic texture inc. phase transformation toughening. Demonstrate the ability to interpret which strengthening mechanisms are present in different materials systems.</li><li>Define what crystallographic texture is and explain how it influences mechanical performance. Make basic predictions of texture evolution from major processing routes i.e. rolling, wire drawing, forging.</li><li>Understand how microstructure can be controlled through processing inc. recovery, crystallization and grain growth and the evolution of texture, include example key microstructures.</li><li>Describe how manufacturing processes can lead to materials defects and understand the underlying processes relevant to their formation and control.</li></ul> <ul><li>Identify major failure mechanisms for brittle and ductile materials inc. microvoid coalescence, transgranular cleavage, intergranular failure and fatigue from the appearance of fracture surfaces and demonstrate understanding of how these features were formed</li><li>Evaluate and choose the best material for a specific application using Ashby diagrams and further construct an appropriate processing route for performance optimization balanced via the production route.</li></ul> <ul><li>Discriminate between different thermomechanical processing routes and select the appropriate route to achieve certain end results through the use of TTT diagrams, and the use of quenching, ageing etc.&nbsp;</li><li>Define the stress concentration, k, and stress intensity factor, K, related to fracture mechanics.&nbsp; Predict K and justify its appropriate application</li><li>Manipulate data using statistics to understand the mechanical properties of brittle materials using Weibull modulus</li></ul> <ul><li>Solve numerical problems.</li><li>Understand the 3-dimensional nature of materials microstructure</li><li>Write concise and relevant reports in an appropriate format following the guidelines given.</li></ul> <p>Lectures will be used to introduce fundamental concepts illustrated with practical examples of engineering alloys and ceramics. Multiple tutorials assessed (summative) and non-assessed (formative) will be used allowing students to work on specific problems supported by graduate teaching assistants. Additional electronic learning resources will be provided through Canvas.</p> 1 Written exam 70% 7 Oral assessment/presentation 30% <p>Feedback given written and verbally.</p><p>&nbsp;</p> N <div><p>The recommended reading for this unit can be found on the <a href="https://www.readinglists.manchester.ac.uk/leganto/readinglist/searchlists/347190680450001631">online unit reading list</a>.</p></div> Lectures 30 0 120
