This includes providing the background theory and quantitative understanding required predicting phase transformation kinetics.&nbsp;Topics include:</p><ul><li>Overview of different types of transformations and example applications.</li><li>Fick’s laws of diffusion, diffusion mechanisms, Kirkendall effect.</li><li>1^st order, nucleation and growth, homogenous and heterogenous.</li><li>2^nd order instability in solutions - spinodal decomposition and ordering.</li><li>Growth mechanisms (1. Interface controlled, massive transformations, 2. Long range diffusion controlled, 3. Mixed, e.g. ledge migration).</li><li>Order/disorder diffusionless reactions, massive and martensitic transformations.</li><li>Introduction to overall kinetics and TTT diagrams (including Avrami equation).</li><li>Introduction to solidification. Types of interface undercooling, constitutional undercooling, primary phase growth morphologies.</li></ul> <p>The unit aims to:&nbsp;</p><ul><li>Provide a fundamental understanding and quantitative description of the important phase transformation mechanisms in metallic, ceramic, and polymeric systems.&nbsp;</li><li>Provide an understanding of the importance of phase transformations in determining microstructure and an ability to classify phase transformations by type.&nbsp;&nbsp;</li><li>Provide a quantitative understanding of diffusion, nucleation, growth, and overall transformation kinetic theory.</li><li>Provide a foundation in solidification theory including quantitative descriptions.</li></ul> <p>A greater depth of the learning outcomes will be covered in the following sections:</p><ul> <li> Knowledge and understanding</li> <li> Intellectual skills</li> <li> Practical skills</li> <li> Transferable skills and personal qualities</li></ul> <ul><li>Understand the important classes of phase transformations in materials (metallic, ceramic, polymeric).</li><li>Understand the importance of phase transformations and their relation to microstructure.</li><li>Understand the mechanisms of diffusion in materials.</li><li>Understand Ficks 1st and 2nd laws of diffusion.</li><li>Understand nucleation theory, including solid-state nucleation (homogeneous and heterogeneous).</li><li>Understand the difference between 1st and 2nd order phase transformations and give examples of both.</li><li>Understand growth mechanisms during phase transformations.</li><li>Understand and describe non-diffusional phase transformation mechanisms in materials.</li><li>Understand how solidification occurs in materials, including a quantitative ability to predict conditions for interface instability.</li><li>Understand overall phase transformation kinetics for diffusional and diffusion-less transformations.</li></ul> <ul><li>Use Fick’s 1st and 2nd laws to solve diffusion problems.</li><li>Use nucleation theory to predict nucleation rates for phase transformations.</li><li>Predict the conditions for interface stability during solidification.</li><li>Create and interpret a time-temperature-transformation (TTT) diagram.</li></ul> <ul><li>Use image analysis to quantify a microstructure.</li><li>Use the MATLAB computer language to run a simple model and interpret the results.</li></ul> <ul><li>Familiarization with the MATLAB computer language.</li><li>Experience and familiarization with image analysis techniques.</li></ul> <p>Lectures, laboratories, recommended textbooks, web resources, past exam papers, electronic supporting information (Canvas), peer-assisted study sessions (PASS).</p><p>This unit is delivered using a blended learning approach, which integrates technology and digital media with traditional classroom activities. A variety of learning and teaching processes will be used including: lectures, discussions, group activities and independent study. Canvas will be used to present online study materials, including videos, lecture notes, guided reading, articles and other information. Canvas will also be used for the submission of assessments. &nbsp;</p> 1 Written exam 70% 2 Written assignment (inc essay) 30% <p>Written and verbal</p> N <div><p style="text-align:justify;">The recommended reading for this unit can be found on the <a href="https://www.readinglists.manchester.ac.uk/leganto/public/44MAN_INST/lists/338986348730001631?auth=CAS">online unit reading list</a>.</p></div> Lectures 22 0 78
