This PhD project is part of the Cotutelle arrangement between Coventry University, UK and Deakin University, Melbourne, Australia.
The successful applicant will spend the 1st year at Deakin University and the following year at Coventry University and then the final 1.5 years at Deakin University.
The supervision team will be drawn from the two Universities.
Ultra-High Strength Steels (UHSS) such as dual-phase ferritic-martensitic DP1000 or DP1200 grades have been recently developed to produce automotive components with increased impact safety and reduced weight. DP1000 and DP1200 steels contain high volume fraction of martensite and are therefore predominantly hot formed because at room temperature stress localisation at the ferrite/martensite interfaces causes early failure by interphase de-cohesion.
A unique Flexible Roll Forming (FRF) facility has been developed at Deakin University in order to expand formability of materials not normally formable at room temperature by introducing non-linear strain paths and reducing localised strain concentrations. This project will utilise the FRF facility at Deakin University to study the formability of DP type steels with varying content of annealed martensite that will be supplied by Tata Steel RD in the form of sheet material subjected to different heat treatments.
The main scientific objective of this project is to develop microstructural based FE model describing the role of varying strain paths on bendability of steels with varying volume fraction of martensite. Aim is to successfully realise conventional and flexible roll forming of UHSS DP steels.
