Study-Unit Description


TITLE Principles of Materials Engineering

LEVEL 01 - Year 1 in Modular Undergraduate Course


DEPARTMENT Metallurgy and Materials Engineering

DESCRIPTION This study-unit introduces the student to a broad overview of the basics of Materials Engineering, Materials Science, Material Processing, Material Degradation and Material Failure.

This study-unit presents a brief recollection on the different classes of materials (metals, ceramics, polymers and composites). The properties and manufacturing techniques of the afore mentioned materials will be outlined.

Corrosion, wear, creep and failure are introduced and their implications outlined. This includes basic terminology and important parameters affecting chemical, electrochemical and physical degradation. Principles of ductile and brittle fracture and common corrosion and wear mechanisms are introduced. These degradation mechanisms will be explained in context of the application and possible solutions will be given. The variables affecting fatigue behaviour and material susceptibility are also presented. The different stages of fatigue and creep are outlined and experimental methods for life prediction are explained.

Study-Unit Aims:

This study-unit aims to:

- Provide the student with knowledge and understanding of the four different classes of materials and their properties.
- Introduce the fundamentals of corrosion science and tribology.
- Provide a comprehensive introduction to material deformation and failure underlying the differences in material response to static and dynamic loading at low and relatively high temperatures.
- Familiarise the student with material failure modes and the necessary tools to understand flaws in material and product design.
- Enable students to understand the effect of manufacturing processing, material processing routes and environmental operating conditions on failure of materials.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:

- List and describe the four different classes of materials;
- Contrast the different material properties;
- Demonstrate an understanding of the principles of corrosion and wear;
- Contrast the different material properties in terms of material failure and degradation;
- Comprehend the most important concepts related to fracture mechanics;
- Comprehend the basic material fatigue mechanisms.

2. Skills:

By the end of the study-unit the student will be able to:

- Select a specific material for a particular situation that requires a set of material properties;
- Corollate the principles of material degradation & fracture to a specific material property;
- Design tests for the evaluation of creep and fatigue resitstance;
- Select suitable non-destructive testing techniques for quality control and failure prevention.
