Research Assistant/Associate  - Metallic Glasses: Thermomechanical Treatments to Modify Structure

University of Cambridge - Department of Materials Science and Metallurgy

West Cambridge

Fixed-term: The funds for this post are available for 1 years in the first instance.

Grade 5 - £25,298-£29,301

Grade 7 - £30,175-£38,183

This Research Assistant/Associate position is one of three linked positions, all supported by the European Research Council (ERC) Advanced Grant 'Extending the range of the glassy state:  Exploring structure and property limits in metallic glasses' held by Professor   AL Greer.  Metallic glasses (MGs), which are among the most actively studied metallic materials, have attractive mechanical properties.  The as-cast state of MGs can be altered by thermomechanical treatments: rejuvenation (to higher energy) offers improved plasticity (perhaps even desirable work-hardening); relaxation (to lower energy) offers access to ultrastable states. The ExtendGlass project aims to widen the range of glassy states and to explore the consequences of unusual states, particularly for mechanical properties and for phase stability/crystallization.

MGs undergo changes in structure and properties, even when the directly applied or induced strains are well within the nominally elastic range.  Examples of treatments include thermal cycling (including cryogenic), static loading, stress cycling and application of ultrasound.  Little has been done to optimize these treatments, in particular to identify the temperature ranges in which they are best applied.  This project will characterize beta relaxation and other dynamic effects in MGs, and will explore the general coupling between thermomechanical treatments and structural changes in MGs, including rejuvenation/relaxation of the glassy state and crystallization.  For this post, experience of techniques such as mechanical testing, dynamic mechanical analysis (DMA), thermomechanical analysis (TMA) or resonant ultrasound spectroscopy (RUS) is essential.

Applicants must have a strong academic research record in materials science or a closely related discipline. They should have, or expect soon to gain, a PhD in materials science, mechanical engineering, or a closely related discipline.
