PhD Project in Materials Science & Mechanics of Materials
-Metal-metal Solid Bonding Technique
Supervisors: Dr Jun Jiang (Senior Lecturer), Mechanical Engineering Department
Deadline for applying: until post filled
Potential funding mechanisms: CSC-Imperial Scholarship, Imperial College President Scholarship, Mechanical Engineering Departmental Scholarship+CSC, or from other government and private funding sources
Applications are invited for a research studentship in the field of advanced manufacturing technologies, leading to the award of a PhD degree. The position is supported by various industry stakeholders, including Commonwealth Fusion Systems, UKAEA, Alfa Laval, SMT and British Geal Associate. emphasising its significant industrial relevance and potential.
Dr Jiang's group at Imperial College has invented a ground-breaking solid-bonding technology that seamlessly integrates cold bonding with diffusion bonding, all in open-air conditions. This innovative method has demonstrated exceptional results such as maintaining base metal properties with minimal deformation. Its advantages encompass high joint strength, precision, cost-effectiveness, scalability, and much more, earning its 1st place in the Fusion Manufacturing Challenges 2023 at TechConnect, Washington.
The prime focus of this PhD will be to develop and optimise this revolutionary welding technique for manufacturing industry-representative nuclear fusion components (like tungsten-316L or vanadium) or creating bimetallic Al-Fe lightweight gears for transmission systems. With access to the state-of-the-art Gleeble 3800 testing facility, the candidate will investigate deep into understanding the intricacies of bonding mechanisms. This will encompass studies on oxide evolution, grain boundary migration, and void closure. Using cutting-edge in-situ thermal micromechanical testing and characterisation units Tescan Clara+ Oxford Instrument EBSD Symmetry 2, EDX, the student will explore the microstructure evolution at the solid bonding joints. Furthermore, the project will also encompass developing physically constitutive equations to numerically portray these bonding mechanisms, facilitating the simulation and optimisation of the welding process.
Idea candidates should be passionate, self-motivated, and meet the academic prerequisites for enrolment for the PhD degree at Imperial College London. Possession of a 1st class honours degree in Mechanical/Material Engineering, or a related field is essential. The student should demonstrate robust project and communication skills and possess a keen interest in advanced manufacturing welding, mechanics of materials and materials science.

Dr Jun Jiang (JJ), the supervisor (2022 Imperial College President Award for Excellence in Research Supervision), (h-index 36, 103 publications; 3500 citations), is a distinguished Senior Lecturer at the Dept. of Mech. Eng., Imperial College London, and is emerging as a leading figure and rising star in solid welding. New Ideas: JJ devised an innovative Hybrid Solid-state Extrusion Roll Welding Additive Manufacturing (AM) Technology, addressing high-strength aluminium alloys' AM hot cracking issues. JJ also pioneered a groundbreaking Hybrid AM and Hot Forge Welding Technology to solve the issues in remanufacturing. New Tools: JJ established a pioneering In-situ Thermal Micromechanical Testing-Characterisation Modelling methodology by winning £380k EPSRC equipment funding in 2020. Combined with JJ’s expertise in crystal plasticity finite element modelling, this novel methodology enabled the process-microstructure performance relationship to be established. New Knowledge: Studies on similar metal diffusion welding and dissimilar metal (Fe-Al) forge welding, provide valuable new scientific insights, as published in esteemed journals such as Acta Mater., Int. J. Mach. Tools Manuf. Recognitions: JJ's exceptional academic performance has been recognised through the Imperia College President's Medal for Outstanding Research Team (2022): and the Imperial College President's Award for Outstanding Early Career Researcher (2018). Furthermore, the proposed transformative solid welding technique won the 1st position of ~30 teams at the 2023 Fusion Manufacturing Challenges.
