Objective

Project Actress will investigate the role of austenite strengthening on bainite transformation and therefore on microstructure and product properties. Showing characteristics that differ from ferrite-pearlite and martensitic transformations, many features of the bainitic transformation are not yet understood and this project addresses this issue.

The research will be focused on modern bainitic micro-alloyed steels based on those for pipeline applications having a clear need for optimisation. An extensive test programme will involve hot rolling simulation, laboratory and industrial rolling. The experimental approach will complement metallographic observations, measurements of mechanical properties and accumulated stress; an innovative method of determining austenite strengthening due to incomplete recrystallisation during rolling.
