Bulk metallic glasses (BMGs) are gaining attention for structural applications due to their exceptional strength and high elastic limits. This study uses a statistical approach to investigate the fundamental physical dynamics behind deformation at the atomic level and the temperature-dependent properties, based on over 100 tests per sample under varying structural and thermal conditions. Nanoindentation tests were performed on a Zr-based BMG to measure key properties such as hardness and provide insights into the deformation behaviour. By analysing nanoindentation data—specifically plotting load over-displacement versus displacement—the study revealed new insights into deformation dynamics, including the identification of the first serration and a precursor event [1]. Further investigations explored how the microstructure of BMGs in different structural states influenced these deformation events. The results showed that precursor events are tied to unstable regions within the material rather than being directly affected by the broader microstructure. The temperature dependence of mechanical performance was also examined, ranging from room temperature to the glass transition and crystallization temperatures. BMGs demonstrated softening behaviour below the glass transition temperature, and the activation energy for softening remained consistent across different structural states, reinforcing the idea of a localized mechanism driving the deformation [2]. These findings offer a deeper understanding of the physical processes governing deformation and temperature-dependent properties in BMGs, which could aid in their design and application across various industries.
