As a materials scientist, I study the effect of microstructure on materials properties and performance and try to understand how materials fabrication routes (manufacturing processes) affect microstructure and therefore the performance of materials. The knowledge so developed should enable us to manipulate process parameters to achieve the desired microstructure and the required properties for specific application. My main research area is on solidification and casting of engineering alloys with main emphasis on aluminium alloys and steels. As physical metallurgist, my research activities in the past thirty years were in the following areas;
Advanced Manufacturing Processes - Near Net Shape Forming (N2SF)
The term near net shape forming, N2SF, covers a wide range of manufacturing routes where there is no need for major post manufacturing treatments. This includes die forging and permanent mould casting. For casting, it covers the techniques where the as-cast product does not require any (or at least a minimum amount of) post-solidification treatments. These are the following operations;
- Removal of feeding system
- Cleaning and removal of cores
- Machining
- Heat treatment
In this regard, it is anticipated to have metallic moulds in most cases, together with specialized machines and/or procedures to classify a casting technique as the “Near Net Shape Casting”, N2SC. The key word here is “precision”. The main N2SF techniques used in my research are;
- Semi-Solid Processing of Metals
- Squeeze Casting
- Die-Casting (high, Low & Gravity)
- Powder Metallurgy
- Additive manufacturing (powder bed Selective Laser Melting)
Advanced Materials
As a physical metallurgist, my main research is concentrated on metallic materials and their composites with almost 80% of my research is concentrated on light metals including aluminium and Ti alloys and a range of steels. Since energy is an important factor in advancement of any society and the industry and almost 60% of energy wasted as heat, I have been researching some of materials which are able to convert the waste heat into electricity and that's why our recent activities are also concentrated on thermoelectric materials such as Bi2Te3 and Heusler and half Heusler alloys such as NiMnSn, NiMnCoSn, CoVSn alloys. These are the materials studied in the past 30 years;
- Light Alloys, (Aluminium, Ti, Mg alloys)
- Steels
- Energy Converting materials (thermoelectrics, Heusler and half-Heusler)
- Advanced Composite Materials (Metal Matrix Composites & Intermetallic Matrix Composites)
Thermal, Mechanical and Thermo-mechanical Processing of Materials
In order to improve the properties of as-cast structures and reduce the non-uniformity in composition and microstructure, the as cast products usually undergo a thermal, mechanical or thermomechanical treatment prior to final shaping and usage in service. In this regard, it is important to understand the mechanism and kinetics of changes to ensure the desired outcome is achieved. Hot and cold forging and rolling along with controlled environment heat treatment processes were part of my research to optimise microstructure and mechanical properties of the semi-finished (blooms, billets and slabs) and finished shaped products.
- Forging
- Rolling
- Heat treatment
Materials Performance
The way materials behave during service is an important step to predict the useful life of a range of engineering finished products. The way materials behave during cyclic loading (fatigue), or high temperature loading (Creep, Oxidation) or aggressive environment (corrosion) or even in an assembly configuration (wear) provide vital information on engineering parts integrity. The main area of materials performance in my research was on weld metal susceptibility to hydrogen embrittlement and wear although as consultant I advised different firms on fracture, fatigue and creep failure of materials in real life applications.

My core lecture room teaching activity started in early 1990 although I was involved casually in teaching since my PhD studies during 1980-83. The teaching covers general and specialists topics in materials. It is mainly concentrated on materials processing, selection and characterization at both undergraduate and graduate levels. I have lectured to a diverse ethnic and national groups in different countries (Australia, England, Iran, Canada) in four continents. The following lectures were delivered at undergraduate and graduate levels;
- Undergraduate Courses
1- Diffusion and Deformation
Third year subject; based on microstructural characteristics of materials on atomic scale, Syllabus were developed and Lectures, Tutorials and Practicals designed and delivered.
2- Fundamentals of Composite Materials
Syllabus was developed and Lectures and Tutorial/Practicals designed and delivered.
3- Diffraction and its application in materials characterization
Lectures and Tutorials/Practicals were designed and delivered on X-ray and Electron diffraction principles and their applications in materials science and engineering.
4- An Introduction to Engineering Materials
First year engineering subject, all disciplines
5- Electrical Eng. Materials
Selection and properties of materials for electrical engineers
6- Heat Treatment of Engineering Alloys
Fundamentals of heat treatment for steels, cast irons and non-ferrous alloys of Aluminium and Copper
7- Solidification and Foundry Technology
Fundamentals of solidification, Principles of semi-finished and shaped casting
8- Manufacturing Processes (mechanical Engineering 3rd year)
Rolling, Forging, Extrusion, Casting, sheet metal forming...
9- Materials selection and failure analysis
After an analysis of different materials and processes and different failure of materials, techniques available for materials selection are discussed. A detailed failure analysis procedure is also introduced.
10- Steels metallurgy
Phase transformation, alloy elements effect on steel microstructure and properties of steels are discussed
- Postgraduate Courses
1- Advanced Solidification Processing
2- Metallurgy of Aluminium Alloys
3- Advanced Composite Materials
4- Diffusion in solids
5- Deformation and dislocations
