A wide range of steel types can be produced by continuous annealing. It would be very beneficial to be able to predict microstructure and mechanical properties from a knowledge of steel composition, hot and cold rolling conditions and continuous annealing parameters. Such a predictive model would help to identify optimum conditions for continuous annealing for improving the properties of existing steels and would aid the development of new steels. There is a need to gain a fuller understanding of annealing conditions on recrystallisation, grain growth, carbide dissolution and texture development in current aluminium-killed and interstitial-free steels. There is also a need to learn more about the relationship between processing conditions, microstructural development and properties in ferrite-bainite, ferrite-martensite and multi-phase steels produced by intercritical continuous annealing. The microstructures of a wide range of continuously annealed steels will be characterised and mechanical properties measured. The relationships between processing conditions, composition, microstructure and properties will be examined in detail. From this, a mathematical model would be developed to predict microstructures and properties from compositional and continuous annealing parameters.
