# MTE3547 - Materials characterisation and modelling

## 6 points, SCA Band 2, 0.125 EFTSL

#### Offered

Clayton Second semester 2007 (Day)

#### Synopsis

Metals, ceramics and polymers may be characterised using a number of techniques, and some of these will be explored in this unit. The techniques can be broadly split into direct (imaging, chemical analysis) and indirect (scattering) techniques. The principles underlying techniques such as x-ray diffractometry, electron microscopy, photoelectron or mass spectroscopy and gel permeation chromatography are explained. Students will investigate the design of experiments, testing for relationships among variables and curve fitting. Models will be related to the characterization techniques studied by the application of appropriate models to real data.

#### Objectives

Upon successful completion of this unit students will develop skills to be able to:

- Understand the interaction of ionising radiation with materials and the resultant secondary effects; derive the structure factor and extinction law in diffraction events
- Account for the optics in optical and electron microscopy and types of lens defects and the limit of resolution
- Understand the electron inelastic mean free path and the escape depth and their significance in surface analysis
- Interpret results of basic characterisation techniques which include XRD, SEM and TEM
- Recognise the capabilities of a range of other characterisation techniques including XPS/UPS, AES, RBS, SIMS and Massbauer spectroscopy
- Identify significant interactions among variables in an experiment, and design an experiment to extract those interactions
- Use a difference equation to model simple dynamical systems
- Propose and analyse an appropriate model for given scenarios
- Construct a simple simulation using a probabilistic model.
