个人简介
Research in the group, part of the Gordon laboratory, is focused on the micro-mechanics of brittle materials in four areas (i) enhancing plasticity and toughness (ii) the deformation of layered structures (iii) abrasion at high temperatures and speeds and (iv) ceramics processing.
The aim is to understand the factors that control plasticity in harder materials, how these might be manipulated to increase the toughness and to use these to increase reliability and performance of systems under operating conditions.
Various layered structures are also being studied, as these can show increased toughness and strength as well as other effects such as hysteresis or an ability to act as a solid lubricant.
Work on abrasion and abrasive systems is directed towards dramatically improving the materials available for preventing the flow of gas around turbine blade tips. This includes studying the processes that occur during abrasion at high temperatures and at high speeds, the properties required for abrasives operating under these extreme conditions, how they can be fixed to the blade tip.
Work on ceramics processing is focused on powder processing an, in particular, the drying of colloidal films and how cracking might be suppressed.
Experimental techniques such as in situ microcompression, toughness testing, both over a wide range of temperature and under vacuum or inert gas, are being used with digital image correlation and nanoindentation, and in situ synchrotron diffraction are being used together with small-scale testing methods for measuring creep and hysteresis behaviour, together with a range of theoretical methods.
