Understanding the role of nanoparticles in water based lubrication. This project seeks to understand the role of nanoparticles in the lubrication of hot strip rolling and then to develop novel nano-additive water-based lubricants to solve a long-standing issue for the steel-making industry. Lubrication significantly affects the surface quality of hot-rolled strips, roll wear and energy consumption in the steel-making industry. Currently, oil-based lubricants are used. However, their lubricant ef ....Understanding the role of nanoparticles in water based lubrication. This project seeks to understand the role of nanoparticles in the lubrication of hot strip rolling and then to develop novel nano-additive water-based lubricants to solve a long-standing issue for the steel-making industry. Lubrication significantly affects the surface quality of hot-rolled strips, roll wear and energy consumption in the steel-making industry. Currently, oil-based lubricants are used. However, their lubricant effect is considerably reduced by the use of high pressure cooling water, and the waste discharge is of environmental concern. Successful outcomes for the project are expected to improve product quality and reduce resource use.Read moreRead less

To meet the national rail objectives as enunciated in the 2002 Green Paper there is an urgent requirement for a capability for: i) advanced (rail) prototype assessment, ii) rapid assessment of rail infra-structure, iii) for increasing the capacity of existing (rail) infra-structure. To address this we propose a facility with both a dissipative energy measurement and a 'lock in' thermograpghy capability. Recent Australian developments in thermo-elasticity enables the researchers to extend this facility to measure residual stress in complex components. The ability to measure dissipated energy, residual stress, ultrasonic waves, and full field stress will create a unique research capability.Read moreRead less
