Tribological contact of work roll in hot rolling. Steel and aluminium manufacturers form their products by shaping a hot metal billet using, for example, presses and rollers which contact the rapidly cooling metal in the production line. The economic benefits of lubrication, reduced rolling force (up to 25%), reduced roll wear and extended roll life (up to 40%), reduced down time due to roll change, and better strip quality are very significant for these manufacturing processes. This comprehens ....Tribological contact of work roll in hot rolling.

The economic benefits of lubrication, reduced rolling force (up to 25%), reduced roll wear and extended roll life (up to 40%), reduced down time due to roll change, and better strip quality are very significant for these manufacturing processes. This comprehensive program will provide new knowledge on lubrication and roll wear to help Australian manufacturing industry (e.g. steel and aluminium) to better understand and optimise their processes to achieve maximum benefits.Read moreRead less

Control of Thermodiffusion in Liquid Multicomponent Alloys. Aims: The project aims to comprehensively study heat and mass coupling in liquid alloys by describing it mathematically, measuring it experimentally and calculating it by simulation. Significance: When a liquid alloy exists at different temperatures, the coupling of heat and mass flows causes rapid segregation of its components. This is a major complication in controlling solidification from liquid alloys in manufacturing and in the des ....Control of Thermodiffusion in Liquid Multicomponent Alloys. Aims: The project aims to comprehensively study heat and mass coupling in liquid alloys by describing it mathematically, measuring it experimentally and calculating it by simulation. Significance: When a liquid alloy exists at different temperatures, the coupling of heat and mass flows causes rapid segregation of its components. This is a major complication in controlling solidification from liquid alloys in manufacturing and in the design of liquid alloy coolants for efficient heat transfer. It has never been addressed. Expected outcomes: This research is expected to be the pioneering foundation of the area. Benefits: It is anticipated that the research would provide the means to properly control the engineering use of liquid alloys. Read moreRead less
Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductil ....Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductile reinforcement phase and how the cyclic loading influence crack extension within a graded interface. These results will assist in future design and prediction of the in-service lifetime of components containing gradient interfaces.Read moreRead less

Dynamic recrystallization and preferred orientation in ultra-thin steel-strip under conditions of fluctuating temperature and stress. We aim to develop a sound understanding of the origins of ridge-buckle defects in flat-rolled steel sheet and to train researchers in advanced techniques.

We aim to develop a sound understanding of the origins of ridge-buckle defects in flat-rolled steel sheet and to train researchers in advanced techniques. By studying dynamic recrystallisation and texture formation, not of the bulk, but of isolated pockets of material within the bulk that are subject to fluctuating conditions of temperature and stress, defect formation will be related to the intricate interplay between rolling dynamics and microstructural development. Through this new approach a scientifically founded quantitative model should emerge so that defect occurrence can be forecasted, preventative action predicted and industry's competitive position be retained.
