Specialist Subjects:

Microstructure and Microtexture Characterisation
Structure/Property Relationship
Deformation Mechanism
Electron Backscatter Diffraction (EBSD)

My research portfolio over the past 10 years focused on material characterisation, physical metallurgy, materials processing, materials performance, phase transformation and heat treatment, low and high temperature corrosion, structure/property relationship, mechanical property of materials, fracture mechanics, fatigue, microtexture and texture analysis for materials used in power generation, nuclear, automotive and aero-engine applications.

My key research theme is the microstructure/microtexture characterisation of materials to ascertain exact structure/property relationship in various alloys. I believe that understanding and predicting microstructure and texture evolution during material processing, deformation and heat treatment are the foundation of materials property optimisation, designing new alloys as well as the development of the processing and joining techniques. Using a combination of electron microscopy and diffraction-based techniques (including SEM, EDS, EBSD, TEM, XRD, EMPA, GDOES, X-ray Nano and Micro-Tomography, and utilising synchrotron and neutron diffraction facilities) will assist greatly in achieving a comparative characterisation of the microstructures and assess the quantitative utility of different techniques.

  • EGTM04 Project Planning

    Each candidate will prepare a detailed project plan covering background to the research, the scheduling of practical and other work, and milestone deliverables. This plan will be produced following: (i) attendance at specialist lectures covering issues of good practice in the conduct of research eg safety, procedures for laboratory work and data reporting/analysis; (ii) discussion with academic and industrial supervisors regarding technical/commercial issues associated with the specific topic; (iii) a review of the formal course units covering technical issues, personal and professional development and research skills. The overall report must demonstrate that each student relates relevant aspects of the training courses to their industry oriented research project. Not available to visiting or exchange students.
