Modules
Metals
|
This unit covers engineering alloys ranging from light alloys (i.e. aluminium alloys and titanium alloys) to steels (carbon, stainless, and advanced high strength steels). The course centres on the physical metallurgy of such engineering alloys to demonstrate the effect of alloying and its implications for the processing, microstructure and performance of structural pipeline steels, large scale forgings and aerospace components in both airframe and aero-engine applications. Some parallels will also be drawn with the automotive industry, when discussing both steels and light alloys.

Metallurgical Processing
|
This module examines three areas of materials engineering where significant improvement in performance in-service can be obtained via their use. First, the module provides an introduction to the processes and technologies involved in the production of steel, aluminium, and titanium Secondly, methodologies of how microstructure can be significantly improved via thermomechanical processing are investigated and aims to build insight into the operation and capabilities of thermomechanical processing techniques. Finally, this module will describe in detail the underlying engineering principles of plastic forming and focus on some of the main metallic production techniques such as extrusion, rolling and wire drawing.
The aims of this unit are to:
- Develop an understanding of the interaction of metallurgical and mechanical variables in determining microstructural evolution in high temperature solid metal shaping processes;
- Understand in detail the production routes used for the making of steel;
- Understand the production route for other metals such as aluminium and titanium;
- Introduce students to practical analysis of engineering applications using finite elements and to develop an awareness of the power and limitations of the method;
- Understand by use of case studies the mechanics of all the main metal forming operations, such as extrusion and rolling and the relationship between these operations and final mechanical properties

Deformation, Fracture and Fatigue
|
Deformation, fracture and fatigue are important mechanical phenomena in both metals processing and use. The role of dislocations in and the effects of microstructural features on the plastic deformation of metals is initially explored. Consideration of fracture starts with linear elastic fracture mechanics including the Griffith equation and Irwin stress intensity factors. The effects of plasticity effects on fracture in metals including plastic zones at crack tips and cyclical fatigue are considered in some detail. Both total lifetime approaches and damage tolerance approaches to fatigue are considered.
This unit aims to give students:
- develop students’ understanding of the theoretical principles used to describe the deformation, fracture and fatigue of metals
- enable students to undertake fracture mechanics based calculations utilising a stress intensity factor approach
- enable students to undertake fatigue lifetime calculations based on both total lifetime approaches and damage tolerant approaches
By the end of this unit, students will be able to:
- explain the role of dislocations and their interactions with microstructural features in the deformation of metals
- explain the role of cracks and crack like defects in fracture
- undertake stress intensity factor calculations involving a range of crack geometries
- estimate fatigue lifetimes

Heat and Materials with Application
|
This module examines both the transfer of heat to/from materials and thermally activated processes that occur during the manufacture of materials due to the transfer of heat into materials. There is also some consideration of the effects of heat during use. Thus conduction, convection and radiative heat transfer, on their own and in combination are considered, followed by an examination of diffusion (Fick’s laws) and sintering (solid state, liquid phase and viscous glass sintering). Finally creep phenomena are considered.
The aims of the taught component of this unit are:
- Significant insight into the importance of thermal phenomena in the manufacture of materials;
- A sound grounding in and the ability to carry out relevant calculations in heat transfer related phenomena in the context of materials processing ;
- A sound understanding of the processes of sintering in some areas of materials manufacture;
- A sound understanding of the processes of creep that occur when materials are used at a significant fraction of their melting temperature.
The aims of the case study of this unit are to:
- Develop and consolidate the students' knowledge and understanding of high temperature materials and particularly of creep;
- Investigate, in small groups, a topic relating to the processing or use of high temperature materials (e.g. in a gas turbine engine); further experience of working in a team to gather information on the allocated topic and prepare a written report.

How you'll learn |
You will study each module by distance learning. Each module has a scheduled live webinar, which you are encouraged to join, as they include interactive question and answer sessions. These webinars are recorded and are available to all students for revision purposes.
Through these webinar sessions, you will be able to interact with tutors, as well as fellow students from around the world. You will be able to share your experiences of working in industry and gain broader understanding from the other students on the course.
You will be assessed by formal examinations, coursework assignment, a dissertation and a poster presentation, which takes place at the end of the programme in Sheffield.
