Engineering: M2A Fully Funded EngD Scholarship: Development of advanced high strength steel tubes for construction applications

Closing date: 28 February 2018

Key Information

Start date: October 2018

Sponsoring Company: Tata Steel Europe

Academic Supervisor: Dr Cameron Pleydell-Pearce

From London Eye to Wembley Stadium arch, Iconic construction structures have been built with high strength steels. Currently, Tata Steel Europe is developing a new range of hot-rolled and cold rolled steels for such construction applications. These steels offer high strength combined with high tensile elongation and high charpy toughness. This suite of properties enables innovative light-weight designs and is achieved with a mixed ferritic and pearlitic microstructure offering the desired toughness in combination with nano-precipitation hardening for high strength. These steels can further be strengthened by unexplored composite strengthening mechanism by introducing metastable retained austenite phase in the microstructure.  During deformation, the retained austenite transforms to martensite which can postpone the failure (Transformation Induced Plasticity) resulting in higher strength and toughness which makes the steel indispensable for Earth quake and fire resistant applications. The PhD research project will contribute towards novel alloy development and an improved understanding of the relationship between process, microstructure, and properties of Advanced High Strength Steels which may contribute to further process optimization in order to produce higher strength products for structural applications.

Project Aims:

Chief aim of this project is to design  and develop a metallurgical processing route allowing maximising the strength and impact toughness of High strength steel for constructions applications.

  1. Conduct pilot lab casting, hot-rolling and mechanical testing in order to assess influence of process variables on mechanical properties.
  2. Conduct small-scale in-situ/quasi-in-situ experiments combining Electron BackScatter Diffraction (EBSD) and Tensile testing to understand the role of austenite to martensite phase transformation in improving the mechanical performance.
  3. Combine these studies with ex-situ HR-TEM/STEM-EDS to assess final precipitation state.
  4. Using Focussed Ion Beam (FIB) lift-out method prepare site specific samples for HR-TEM / STEM-EDS and assess the influence of precipitation in relation to ferrite, austenite and pearlite morphology and effective grain size.
