Large-volume gradient materials: Manufacturing and deformation mechanism. This project aims to develop a low-cost and high productivity process to produce large-volume metals with high strength and good ductility, suitable for engineering application. Ultrafine grained (UFG) materials and nano-grained (NG) materials are usually strong, but not very ductile. This project will use an accumulative skin-pass rolling (ASPR) technique to fabricate the metallic strips with gradient structure.

Summary
Fabrication of large-scale two-dimensional metallic nanosheets by accumulative rolling. This project aims to develop new techniques and insight into the thinning of metals from bulk to nano thicknesses which enables bulk manufacturing of large-scale two-dimensional (2D) metallic nanosheets. A novel rolling strategy will be adopted to achieve 2D metallic sheets with thicknesses less than 5nm and lateral sizes larger than 1mm, as well as demonstrating significantly improved electro-catalytic perfo ....Fabrication of large-scale two-dimensional metallic nanosheets by accumulative rolling. This project aims to develop new techniques and insight into the thinning of metals from bulk to nano thicknesses which enables bulk manufacturing of large-scale two-dimensional (2D) metallic nanosheets. A novel rolling strategy will be adopted to achieve 2D metallic sheets with thicknesses less than 5nm and lateral sizes larger than 1mm, as well as demonstrating significantly improved electro-catalytic performance. The proposed technique is expected to be a high-yield, low-cost alternative to traditional bottom-up techniques and is expected to be ready for implementation in industry for bulk manufacturing of 2D metallic nanosheets.Read moreRead less
Environmentally friendly lubricants for higher productivity in cold rolling. This project aims to develop an oil free aqueous lubricant for cold rolling to replace the existing oil-in-water emulsion. The lubricant will be molecularly engineered to combine synergy between nanomechanics and tribochemistry of boundary additives to deliver integrated functionalities in the strip rolling. During cold rolling , lubricant starvation often occurs at high speed and it has restricted the productivity of t ....Environmentally friendly lubricants for higher productivity in cold rolling. This project aims to develop an oil free aqueous lubricant for cold rolling to replace the existing oil-in-water emulsion. The lubricant will be molecularly engineered to combine synergy between nanomechanics and tribochemistry of boundary additives to deliver integrated functionalities in the strip rolling. During cold rolling , lubricant starvation often occurs at high speed and it has restricted the productivity of the rolling mill and affected the strip gauge and surface quality. Expected outcomes of this project include an innovative oil free lubricant with significant environmental benefits and an ability for manufacturers to improve productivity by operating at higher speeds, lower costs, and achieve superior strip surface quality.Read moreRead less
Development of highly formable magnesium sheet. This project will develop alloy and processing technologies that can be used to fabricate lighter and better performing magnesium products. These magnesium products can improve fuel efficiency, resulting in lower emission and environmental pollution.
The phenomenology of unsteady impinging jets: fluid dynamics and heat transfer. This project comprises a definitive study of a fluid jet impacting a target surface and the effect of added fluctuations on its momentum and heat-transfer characteristics. This will deliver new scientific knowledge and underpin the development of an energy-efficient thermal-control technology for widespread use in many areas of engineering.
