SONATA BIS S. BONFANTI

Dr. Silvia Bonfanti is a laureate of the SONATA BIS grant from NCN, titled Impact of Composition and Cooling Rate on Mechanical Properties of High Entropy Metallic Glasses – HIGHENTROPYGLASS

Abstract of the project: Metallic Glasses (MGs) are advanced materials with superior mechanical properties, surpassing traditional metals and alloys. Their unique amorphous atomic structure, achieved by rapid cooling, prevents crystallization, giving MGs extraordinary strength, twice that of titanium. Applications of MGs range from biomedical engineering to aerospace. However, manufacturing challenges arise due to the crystallization tendencies of metallic alloys. High Entropy Metallic Glasses (HEMGs) offer a solution by incorporating multiple atomic elements in equal proportions, improving performance and strength. Despite these advancements, the study of HEMGs is still in its infancy, with uncertainties surrounding how cooling rates and chemical compositions affect mechanical properties. This research aims to address these issues through molecular simulations, machine learning, and nanoindentation experiments. By solving discrepancies between simulations and experiments and optimizing elemental compositions, the project seeks to design HEMGs with tailored properties. Ultimately, this work will bridge the gap between theory and experiments, advancing material science and enabling practical applications.
