Fully-funded PhD Studentship Metallic Glasses Based on Precious Metals

International students are invited for a PhD scholarship in metallurgy at University of Cambridge. This position is available for 3 years. Applications are invited up to December 31, 2018.

Fixed-term: The funds for this post are available for 3 years in the first instance. Sponsor: The Worshipful Company of Goldsmiths Supervisor: Professor AL Greer

Applications are invited for a PhD studentship within the Microstructural Kinetics Group in the Department of Materials Science and Metallurgy. The project focuses on the development and characterization of metallic glasses based on precious metals, particularly gold. Precious metals, in their usual polycrystalline form, have desirable properties for application in jewellery and electronics, but they are soft and lack scratch resistance. Metallic glasses have exceptionally high hardness and scratch resistance [1], and furthermore are susceptible to thermoplastic forming, rather like polymers [2,3]. It is now well established that precious metals can be the basis for glass-forming compositions [4], and that bulk glass formation (minimum dimension mm to cm) is possible. However, much remains to be done to explore the properties and potential applications of precious-metal glasses.

This project will be primarily experimental, but can involve atomistic modelling. It will focus on: the search for better glass-forming alloys; characterization of the structure and stability of the glasses, including the possibilities to obtain crystallized products that have good mechanical properties, and possibly decorative patterns; optimization of the mechanical properties; studies of chemical stability including tarnish-resistance.

Applicants should have (or expect to be awarded) an upper second or first-class UK honours degree at the level of MSci, MEng (or overseas equivalents) in a relevant subject (Materials Science, Physics, Chemistry) and should be liable for ‘home rate’ fees to be eligible for a studentship. The studentship is fully funded, covering fees and a tax-free stipend of at least 18500 per annum.
