I am a PhD student in Loughborough University in Multifunctional Materials Manufacturing lab. My research project is focused on the design, manufacture and validation of biocompatible bulk metallic glasses (BMGs) for orthopaedic application. Educated in materials science and engineering, I obtained my BEng in China in 2019, following an MSc in the University of Sheffield in 2020. I am familiar with various materials characterisation techniques such as XRD, DSC and SEM and did a lot of work to investigate the

THERMEC 2023 – Vienna – (July 2023)
Members of the RIED Loughborough attended the THERMEC 2023 Conference in Vienna, Austria, a very prestigious bi-annual International Conference on “PROCESSING & MANUFACTURING OF ADVANCED MATERIALS: Processing, Fabrication, Properties, Applications”
The work presented was on the biodegradable and bioresorbable materials for medical devices and scaffolds based on Ca-Mg-Zn chemistry for bulk metallic glasses. PhD researcher Shangmou Yang and supervisors Profs Paul Conway and Carmen Torres presented and defended the paper entitled “Can multifunctionality of bioresorbable BMGs be tuned by controlling crystallinity?” during the session ‘Metallic Glasses 3’ chaired by one of them most eminent and internationally respected experts in bulk metallic glasses, Prof Jürgen Eckert, from Montanuniversität Leoben & Erich Schmid Institute of Materials Science, Austrian Academy of Sciences, Leoben (Austria).

It was Shangmou’s first international experience presenting his work; he was well prepared and did a very good job in front of scientists from all over the world who are also working on that alloy system. This work is co-sponsored by Alloyed Ltd, the Wolfson School of Mechanical, Electrical and Mechanical Engineering and EPSRC Programme Grant ‘RIED’.

And to make it even more special…
The RIED-Wien local team came to support us and boost our mood!
We met with Dr Vincent McKenna, RIED alumnus, who now resides in Vienna. It was a fabulous occasion, and we spent a lovely time with him there, celebrating how well he is doing in the city he now calls home. We are already looking forward to meeting him again (here in the UK or in Wien!)

Can Multifunctionality of Bioresorbable BMGs Be Tuned by Controlling Crystallinity ? (June 2024)
As published in Key Engineering Materials Volume 967
Ca-Mg-Zn bulk metallic glasses (BMGs) are promising biomaterials for orthopaedic applications because when they get reabsorbed, a retrieval surgery is not needed. In this study, Ca-Mg-Zn metallic glasses with different compositions, Ca56.02Mg20.26Zn23.72 and Zn50.72Mg23.44Ca25.84, were fabricated by induction melting followed by copper mould casting. Their degree of crystallinity was modified by annealing, obtaining exemplar specimens of fully amorphous, partially amorphous (i.e., a BMG composite (BMGC)) and fully crystalline alloys. The microstructure, thermodynamic and corrosion performance of these alloys were evaluated as well as their electrochemical behaviour. The results of polarisation tests demonstrate that the corrosion resistance of the Zn-rich alloy is markedly better than the Ca-rich BMG. Corrosion rates of these Ca-and Zn-rich alloys with different degrees of crystallinity illustrate that the corrosion behaviours of alloys strongly depend on their microstructure, which shows a positive correlation between the corrosion current density and the crystallised volume fraction of the alloy. This study aims to shed light on the impact of the amorphicity-to-crystallinity ratio on the multifunctional properties of BMGs/BMGCs, and to assess how feasible it is to fine-tune those properties by controlling the percentage of crystallinity.
