Summary on Grant Application Form |
|
Most industrial hot metal working processes involve a significant amount of strain path change. This brings into question the validity of the large strain phenomenological equations that are used as the basis of current industrial thermomechanical process modelling as they are described in terms of equivalent stresses and strains. At the moment, our understanding of the significance of the effects of strain path is limited by a lack of a systematic study. This project aims to undertake this study by investigating and quantifying the influence of strain path on flow stress, microstructure evolution and recrystallisation behaviour. This work will be undertaken using interstitial free (IF) steel using a machine for testing arbitrary strain paths developed as part of EPSRC grant (GR/L11144). The project goals will be achieved by using a phased set of experiments, each with an extra degree of strain path complexity, to build up a systematic understanding of the effects of strain path. To ensure the validity of the test, finite element modelling of the test specimen will be done.IF steel is of great significance to UK industry, particularly the automotive sector. Warm working can significantly reduce costs; therefore this work will concentrate on this temperature range.
