Metallic glasses (MGs) exceptionally combine the strength and elasticity of metals with an amorphous structure, producing amongst the strongest and toughest metals known. Despite their exceptional properties, MGs face a serious problem: they are inherently metastable and known to exhibit abrupt und currently unpredictable property losses such as ageing-induced embrittlement, an experimental observation that lacks a structural understanding. The element-specific X-ray absorption spectroscopy (XAS) technique could be leveraged in this direction, allowing probing structural evolutions in MGs experimentally around individual alloy components. Preliminary XAS data show clear atomic rearrangements as a function of time and temperature around Zr in a Zr-Cu-Al alloy, leading us to the idea of further explore the time-temperature-transformation diagram in the proposed experiment.
