Overview

This unit builds up on general understanding of the principles of advanced engineering materials, including composition-structure-property relationships in metals and ceramics, to develop further understanding of high-performance non-ferrous metallic and non-metallic materials systems, their processing principles and performance in high temperature/demanding environment applications related to transport, energy, chemical and manufacturing industries.

Aims

The unit aims to provide a systematic understanding of fundamental materials science, engineering and performance aspects of high-performance non-ferrous metallic, non-metallic materials systems and coatings related to high-temperature/demanding-environment applications. The main topics to be considered within the unit include:

(i)         Metallurgy, processing and performance of high-performance non-ferrous alloys:

a.         Ti alloys and titanium aluminides for aerospace applications;

b.         Zr alloys for nuclear applications;

c.         Ni base superalloys for high temperature applications;

(ii)        Materials science, processing and performance of monolithic ceramics and ceramic matrix composites (CMCs), for very high temperature applications;

(iii)       Design, engineering and performance of coatings for high temperature and abrasive environment applications.

 

Learning outcomes

A greater depth of the learning outcomes will be covered in the following sections:

  • Knowledge and understanding
  • Intellectual skills
  • Practical skills
  • Transferable skills and personal qualities

Teaching and learning methods

Lectures will be used to introduce fundamental concepts superalloys and high performance materials systems, illustrated by practical examples of their applications. Two tutorial sessions will be used to develop practical skills in the analysis of structure-property relationships in specific materials systems. On-line quizzes will be used to facilitate preparation for these tutorial sessions. The third session will be used to facilitate the work on the case study into application and performance aspects of superalloys and high-performance materials systems. The tutorial sessions will be supported by graduate teaching assistants. Additional electronic learning resources and useful web links will be provided in Blackboard.

 

Knowledge and understanding

  1. Appraise the main industrial, technological and economic drivers for application of difficult-to-shape high-performance metallic, non-metallic materials and coatings.
  2. Classify high-performance HCP metallic, superalloy and non-metallic materials systems based on their composition, properties and applications; identify the main degradation and failure modes for these materials systems in service.
  3. Describe the main orientation relationships, deformation and strengthening mechanisms involved in high-performance HCP, Ni base metallic materials.
  4. Understand the influence of different processing routes on the microstructure and corresponding effects on mechanical properties and in-service performance of Ti- and Zr-alloys alloys, TiAl, nickel-base superalloys, monolithic ceramics, ceramic matrix composites and coatings.
  5. Identify appropriate coating systems and corresponding manufacturing routes for different substrate materials and applications.

 

Intellectual skills

  1. Critically assess the range of technologies available for advanced processing of semi-finished products from the difficult-to-shape materials, outlining the advantages and limitations of each process influencing its application.
  2. Explain the general metallurgical principles that underpin the main deformation and strengthening mechanisms in high-performance non-ferrous metallic and ceramic materials, their links to the microstructural evolution during thermo-mechanical processing and implications for resulting mechanical properties.
  3. Outline the principles exploited in advanced processing to overcome the challenges the current industrial superalloys and high-performance materials present, design microstructures and develop improved properties.

Practical skills

  1. Ascertain the influence of thermo-mechanical processing on microstructure, mechanical properties and in-service performance of superalloys and high-performance materials systems.
  2. Apply general metallurgical and materials engineering principles to the technologies involved in processing of superalloys and high-performance materials to optimise the process and improve component performance.

Transferable skills and personal qualities

  1. Develop analytical skills when working with scientific and technical literature on advanced materials systems.
  2. Write concise, relevant and competent reports in an appropriate format on various aspects of science, engineering and applications of advanced materials systems.
  3. Work systematically and effectively, both individually and in a group, to solve problems related to processing and application aspects of superalloys and high-performance materials.
