Approaches for rapid industrial adoption of new steels

Speaker: prof. Claire Davis, University of Warwick.

Title:
Approaches for rapid industrial adoption of new steels.

Abstract:
How does the academic community support the rapid development and adoption of new steels and processes in the steel industry?

The fundamental principles for developing new steels based on compositional and microstructural design to achieve properties are well developed and practiced, particularly at the laboratory level. However, industrial production generally involves multi-stage processing routes where all stages are important for microstructural development. In order to develop new steels / processes and consider the scale up implications for industrial exploitation, laboratory facilities and modelling need to be capable of replicating all aspects of industrial processing, including the limitations of existing processing plant capability and compositional control. Issues such as cooling rates and segregation during casting, through thickness gradients during thermomechanical processing, and sensitivity to annealing parameters need to be considered.

This lecture will illustrate the major steps that need to be considered and controlled to achieve this using the example of microstructure development during casting, reheating, rolling and annealing for current and novel dual phase steels.
In addition, the role of in-situ microstructural determination techniques will be highlighted.

This session was chaired by prof. Erik Offerman (Delft University of Technology).
