Module content

Indicative content: the course includes lectures and tutorials on:

• The thermodynamic basis of phase diagrams.
• Binary equilibrium phase diagrams and their use in predicting alloy constitution and microstructure.
• Isothermal and continuous cooling transformation diagrams and their use in predicting microstructure.
• Characterisation of microstructures.
• Solid-state diffusion.
• The liquid to solid transformation.
• Precipitation in the solid state.
• The classification of phase transformations as diffusional and displacive.
• The pearlitic, bainitic and martensitic transformations.
• Microstructure, processing and property relationships (with an emphasis on ambient temperature strengthening mechanisms).
• Point, line and planar lattice defects.
• Micro and macro defects.
• Cold work, recovery, recrystallisation and grain growth.
• The role of dislocations in strengthening mechanisms.
• An introduction to the physical metallurgy of high-strength wrought aluminium alloys.
• An overview of titanium alloys.
• An introduction to martensitic, stainless and maraging steels.

Assessment Strategy

The assessment strategy:

Set of short questions (Q1) covering the entire syllabus which require demonstration of an understanding of the underlying issues relevant to a wide range of issues in, and aspects of, physical metallurgy. The long question (Q2) required extensive research to identify and integrate information on an issue central to the understanding and use of alloys in an engineering context. The research is based on information from self-determined sources and an understanding of the core principles covered in the taught material.

Thus, the summative assessment for this unit consists of:
• Q1 (Short answer questions) 50%
• Q2 (Essay question) 50%

Formative assessment
• Formative verbal feedback is given in lectures and tutorials.

Feedback
• Written feedback is given on the submitted coursework

Module aims

  • The centrality of the concepts of thermodynamics and kinetics in physical metallurgy and phase transformations
  • Binary equilibrium phase diagrams as a tool in understanding the thermodynamics of alloy systems
  • The use of transformation (isothermal and continuous cooling) diagrams as a tool in following (i) the kinetics of phase transformations and (ii) the development of alloy microstructure
  • The most common phase transformations that occur in commercial alloys
  • The principles of thermodynamics and kinetics, and their application, to a representative selection of real alloy systems
  • The nature of defects in metallic systems and their role in determining engineering properties
  • The concept of microstructure and its relationship to processing and properties of alloys.

Overall student workload

Independent Study Hours: 30

Lecture Hours: 10

Tutorial Hours: 10

Laboratory Hours: 10

Methods of Teaching / Learning

The learning and teaching strategy is designed to introduce the fundamentals of physical metallurgy through lectures and tutorials.

The learning and teaching methods include:
• 22 hours lectures
• 8 hours tutorial classes
• 30 hours coursework.

The teaching is delivered as a one-week intensive course.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
