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. 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 form ....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. 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.

Summary
High Rate Testing System for Materials and Structures. Human or natural disasters such as terrorist attack or tsunami take place and they have catastrophic consequences, in terms of fatalities and psyche of fear among the population, as well as enormous financial loss. Vehicle accident is another example. In Australia, 1636 people were killed in 1481 road crashes, in 2005 alone. There is a great demand for research into devising novel materials and structures for optimum performance under such c ....High Rate Testing System for Materials and Structures.

Vehicle accident is another example. In Australia, 1636 people were killed in 1481 road crashes, in 2005 alone. There is a great demand for research into devising novel materials and structures for optimum performance under such circumstances. The proposed new high rate testing system will significantly advance research in this area. The facility will directly support a range of research projects in material and structural design in military and civil vehicles, aerospace industry and defence.Read moreRead less
