PhD Studentship - Aluminium-Steel Laser Welding: What Happens at the Interface?

University of Warwick - Centre for Doctoral Training in the Modelling of Heterogeneous Materials (HetSys)

Qualification Type: PhD
Location: Coventry
Funding for: UK Students, EU Students, International Students
Funding amount: See advert details
Hours: Full Time
Placed On: 14th December 2021
Closes: 31st March 2022

Project supervisors: Peter Brommer; Prakash Srirangam

Summary:

Aluminium and steel are widely employed metallic materials for automotive applications, such as in vehicle frames. Joining of these two dissimilar metals by laser welding results in formation of brittle aluminium-iron intermetallic compounds at the interface, which degrade the performance of the weld. Here, you will study the joining process through simulations on an atomic scale, directly exploring how iron and aluminium atoms move into the opposite material during and after laser irradiation, supported by transmission electron microscopy analysis. The aim is to find favourable laser weld conditions to mitigate the formation of brittle intermetallics in this technologically relevant process.

Background:

Aluminium and steel are widely employed metallic materials for automotive applications, such as in vehicle frames. Joining of these two dissimilar metals by laser welding results in formation of brittle aluminium-iron intermetallic compounds at the interface, which degrade the performance of the weld. Here, you will study the joining process through simulations on an atomic scale, directly exploring how iron and aluminium atoms move into the opposite material during and after laser irradiation, supported by transmission electron microscopy analysis. The aim is to find favourable laser weld conditions to mitigate the formation of brittle intermetallics in this technologically relevant process.

The project is focused on understanding the interaction between Fe and Al atoms at the weld interface during laser welding of steel to Al alloy. You will employ atomistic modelling techniques, particularly molecular dynamics (MD) and Kinetic Monte Carlo (KMC) to study atomic motion during and after laser irradiation, as well as the mechanical properties of the weld. The effect of weld parameters on interfacial properties, vacancies and dislocations via mutual diffusion of Fe and Al will be experimentally supported with TEM microscopy analysis performed by an India-based PhD student supervised by Prakash Srirangam.

A better understanding of the formation of brittle intermetallic compounds during laser welding of dissimilar steel to Al would not only lead to improved mechanical properties of weld joints, but also help to achieve net zero emissions with usage of light-weight materials for engineering applications.
