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.
