Summary

This module focuses on understanding and manipulating of materials microstructure to avoid failure. It addresses the main areas of mechanical failure using specific material system examples to illustrate how materials design is used to develop better materials for particular applications. The four areas are:

1. Design for Strength (metallic alloys, ceramics)
2. Design for Toughness (metallic alloys, including discussion of strength/toughness balance for Al alloys)
3. Design for Creep Resistance (metallic alloys)
4. Design for Fatigue Resistance.
    

Re-assessment
Students who fail this module overall and are required to complete a re-assessment will be re-assessed by exam. The re-assessment exam mark along with the ExamSys mark will be used to determine whether students satisfy progression requirements.

Target Students

MSc taught post-graduate students, and 3rd/4th year undergraduates in the Department of M3.

Assessment

• 50% Exam 1 (2-hour)
• 50% Exam 2 (2-hour)

Assessed by end of spring semester

Educational Aims

Learning Outcomes

On successful completion of this module students will be able to:

LO1 – Describe how one might alter the microstructure of a metallic alloy in order to optimise its’ strength.

LO2 – Discuss the strength/toughness balance in the aluminium alloy system.

LO3 – Understand the microstructural and design implications of time dependent and permanent deformation of materials when subjected to a constant load or stress.

LO4 – Describe the fractographic appearance of a fatigue failure and discuss measures used to increase fatigue resistance.
