Brief Description (including aims of the course):
This course seeks to develop the student’s understanding of the processes by which materials deform at high temperature, how key microstructural parameters change with time at temperature (thereby changing mechanical properties) and damage accumulates ultimately leading to failure. It will relate these fundamental mechanisms to microstructural design of key high temperature materials, including Ni-base superalloys, high temperature Ti alloys, Ti-Al intermetallics, and coatings. It also introduces students to the range of ceramic materials used in high temperature aerospace applications including space shuttle tiles, stealth bomber and fighter skin structures, thermal barrier coatings in jet engine components including blades and missile radomes.
Course Objectives:
By the end of this course, you should be able to:
•Display understanding of the fundamental factors that control microstructural stability and damage accumulation in high temperature metals and intermetallics;
•Demonstrate knowledge of the various forms in which high temperature materials are used and how they are made and from that determine the microstructures and processes developed to optimise advanced high temperature applications;
•Outline the range of ceramic materials used at high temperature in aerospace applications;
•Consider the various forms in which high temperature ceramics are used such as coatings, fibres and composites and how they are made;
•Display awareness of the processing/property/structure relations of ceramics;
•Handle simple quantitative descriptions of ceramics strength, toughness and thermal shock resistance;
•Demonstrate understanding of failure mechanisms in ceramics at high temperature;
•Demonstrate understanding of fundamental factors that control microstructural stability and damage accumulation at high temperature under stress.
