The aim of this module is to discuss high performance materials used in demanding applications. This will cover a range of materials (Ti based alloys, Steels, Ni-based superalloys and Al based alloys) designed for very specific application i.e. Creep-resistant Ni-based alloys for gas turbine blades. The manufacturing processes for these alloys and applications will be discussed in detail and will include; investment casing, additive manufacturing and advanced joining techniques amongst others.
Industry requirements and constraints as well as performance indices for these materials will be covered.
These link to the following topics in the 2017 QAA Materials Subject Benchmark Statement: ii phase equilibria and phase transformations, multiphase materials, thermodynamic and kinetic aspects iii structure on the nano, micro, meso and macro scales. iv mechanical behaviour - elastic and plastic deformation, creep and fatigue, fracture, strengthening, toughening and stiffening mechanisms vii materials synthesis - vapour, liquid, colloidal, powder and solid-state deposition techniques viii bulk processing, heat and mass transfer, and fluid mechanics ix joining methods, surface treatment and the application of coatings x layered and additive manufacturing techniques, for example 3D printing, including the creation of 'intelligent' products by incorporating sensors and so on. xi materials design - compositional variation and processing to achieve required microstructures, and hence properties xii materials selection - consideration of all material types, materials processing methods, and product costs xiii degradation/durability of materials - effect of environment upon performance, corrosion, wear, and biodegradation iv engineering principles: including design, manufacturing and processing x an awareness of health and safety, sustainability and environmental issues, and of ethical considerations

Analyse complex problems to reach substantiated conclusions using first principles of mathematics, statistics, natural science and engineering principles (C2)
Evaluate the environmental and societal impact of solutions to complex problems and minimise adverse impacts (C7)
Use practical laboratory and workshop skills to investigate complex problems (C12/M12)
Select and apply appropriate materials, equipment, engineering technologies and processes, recognising their limitations (C13/M13)
Discuss the role of quality management systems and continuous improvement in the context of complex problems (C14/M14)
Apply knowledge of engineering management principles, commercial context, project and change management, and relevant legal matters including intellectual property rights (C15/M15)
Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Much of the knowledge will be at the forefront of the particular subject of study and informed by a critical awareness of new developments and the wider context of engineering (M1)
Evaluate the environmental and societal impact of solutions to complex problems (to include the entire life-cycle of a product or process) and minimise adverse impacts (M7)
