Engineering: M2A Funded EngD Scholarship: Effect of Steel Cleanness & Solidification on Product Performance

Closing date: 28 February 2018

Key Information

Start Date: October 2018

Sponsoring Company: Tata Steel

Tata steel offers a wide range of steel strip products such as HSLAs, AHSS and UHSS for engineering and automotive applications. Structural steel parts for automotive body in white, BWI, chassis and suspension, C&S, as well as structural hollow sections for engineering parts are common applications. Manufacturing practices during steelmaking and continuous castings will determine the steel cleanness and internal segregation in the final slab. These material  characteristics are revealed in the final strip steel product in terms of inclusion distribution, microsegregation and/or  banding. This project will study the effect of these microstructural features on the product quality and performance.

Project Aims:

  • The objective of this project is to carry out an assessment on the effect current steelmaking and continuous casting conditions on the product performance of selected hot rolled products i.e. HSLAs and AHSS
  • Comparison of different casting routes (CC1, CC2, CC3) and identification of optimum manufacturing conditions to reduce micro-segregation and banding
  • Assessment of steel cleanness and identification of possible improvements i.e. reduction of [S], [P] content, optimum Ca-treatment conditions
  • Recommendations to improve manufacturing and product performance

Proposed Activities:

  • Assessment on the effect of manufacturing conditions and different continuous casting routes, considering current internal quality classifications (i.e. Inter-columnar, centre-line segregation), Sampling and characterisation of material as cast. Quantification of macro and micro segregation at this stage.
  • Sampling and characterisation of the final HR product. Identification of main microstructural features, i.e. phases, banding, inclusion distribution. Measurement and comparison of relevant mechanical and performance test (i.e. Fracture toughness, bending, weldability, HE, fatigue).
  • Study the effect of steelmaking conditions, the presence of harmful impurities such as [O], [S], [P], [Al] and relevant inclusion distribution i.e. optimum Ca treatments.
  • Use of numerical modelling techniques to understand and validate experimental data. Available software packages such as ThermoCalc, will be used to study equilibrium phases present during solidification. Other numerical models will be considered.
  • Recommendations for optimum manufacturing conditions to improve product quality and performance.
