Investigating the structure of bulk metallic glasses using isotopic substitution

Abstract: We propose to undertake calcium isotopic substitution on two Mg-Zn-Ca bulk metallic glasses which show considerable promise for use as medical implants. Glasses in the Mg-Zn-Ca system have elastic moduli comparable to that of human bone, which minimises stress mismatch for orthopaedic applications and they have been shown to be biocompatible, depending on the concentration of Zn. In order to model and predict the behaviour of these materials and potentially optimise these glasses for implantation it is important to have a good understanding of the local structure and how this impacts macroscopic properties such as surface charge and corrosion. We therefore propose to undertake a detailed atomic-scale structural study of these materials by investigating compositions containing a high Zn concentration which is biocompatible and a low Zn concentration which is prone to corrosion.
