PhD Studentship: Deformation Mechanisms Across a Chemically Graded Bond Zone

About the role

The University of Cambridge offers a 3.5-year PhD studentship in the Department of Materials Science and Metallurgy, within the Structural Materials Group, funded by the EPSRC and Rolls-Royce plc. The project studies deformation mechanisms across a chemically graded bond zone formed by transient liquid phase (TLP) bonding of nickel-based superalloys, in close collaboration with Rolls-Royce plc. It focuses on alloy selection, interlayer chemistry, crystallographic misalignment and bond processing parameters.

Key responsibilities

• Fabricate TLP-bonded specimens joining like and dissimilar single-crystal superalloys.
• Carry out miniaturised electro-thermal mechanical testing to assess deformation and recrystallisation behaviour.
• Analyse samples using high-resolution electron microscopy and in-situ synchrotron X-ray diffraction to reveal bond-specific micromechanics and phase evolution.
• Produce results that inform processing guidelines for TLP-bonded components in next-generation aero-engines.

Required profile

• A good UK Master's degree (or overseas equivalent) in a relevant science subject such as Materials Science, Chemistry, Physics or Engineering.
• Self-motivated, able to take ownership of research and communicate findings effectively.
• Previous experience in the methods is advantageous, though training in computational and experimental techniques is provided.

What we offer

• Full funding for 3.5 years, including a personal maintenance stipend starting at £22,437 per year, with a £5,500 annual top-up from Rolls-Royce plc.
• Positions are open to UK citizens and overseas students meeting UK residency requirements; exceptional overseas candidates may be eligible for an International Doctoral Scholar award.

Applications are made through the University's postgraduate application portal, quoting reference LJ51573. The closing date is 1 December 2026, with interviews shortly after.
