Engineering: Fully Funded M2A EngD Scholarship: Liquid Metal Embrittlement of Galvanised High Strength Steels

Start date: October 2022

Expected interview date: April 2022

Academic supervisors: Professor David Penney and Dr Amit Das

Industrial supervisors: James Lelliot

Sponsoring company: TATA Steel

Background:

Tata Steel UK is the UK’s primary manufacturer of Automotive metallic coated sheet steel. One of the latest issues arising in Automotive design and engineering is the adaption of dual-phase (DP) steels at 1200MPa strength and above into new vehicle designs. Dual-Phase steel grades give very high yield strength without having a large compromise of ductility. These steels are adapted to allow light-weighting and increased safety performance of vehicles; however, the composition of these steels also causes Liquid Metal Embrittlement (LME) when welded to Galvanised (GI) and Zinc Magnesium (ZM) metallic coated steels for parts such as body side outer panels in automotive chassis’. This is driving automotive companies to adopt expensive Galv. Annealed (GA) coatings for components attached to the Ultra High Strength Steels (UHSS) rather than using more GI and ZM coatings produced within the UK.

Project Aims:

The aims for this program of work are:

  1. Identify the root causes of LME associated with both GI and ZM coated steels
  2. Identify why GA coated steels are less susceptible to LME
  3. Trial and develop solutions to allow GI and/or ZM coated steels to be utilised in a cost effective and robust way when welded to UHSS steels such as DP1200 (this must align to typical vehicle manufacturing conditions i.e. speed of weld, type of weld etc)
