Research interests
 
Microstructure-property relations for structural materials particularly Ti and Ni alloys. The behaviour of materials in high performance applications including their use in extreme environments. Industrial and technology policy especially where these involve materials.
 
Current research includes:
 
• Fatigue crack initiation in Ti alloys as affected by microstructure including microtexture.
• The role of processing on the fracture toughness of high strength Ti alloys.
• The causes of the dwell fatigue phenomena in near α Ti alloys.
• Practical use of modelling and simulation in accelerating the service introduction of new metallic alloys.
• New processes and approaches for making lower cost components from Ti and Ti alloys.
