Abstract
Abstract Metallic glasses (MGs) that mainly made up of metallic elements are a new member of the glassy materials family. This new kind of glass combines the characteristics of liquids and solids, glasses and metals, making it fascinating to both scientists and industrialists. With the discovery of more and more systems, MG is becoming one of the most active research field in metallic materials, and some concepts and technologies derived from MGs also facilitate the development of other materials from quasi-crystals to high entropy alloys. MGs have now been successfully used in aerospace, robotics, medicine, consumer electronics, etc. and the practical applications of MGs are still growing. On the other hand, the diverse properties and the unique structure of the MGs render them ideal models to study major open issues including the structural model of disordered materials, glass transition, collective motion and energy landscape. However, understanding the emerging properties and phenomena of MGs still poses enormous challenges, which has stimulated a wealth of efforts, including the development of new experimental approaches, the synthesis of systems with tailored properties, and the advancements in experimental techniques, theoretical models, and numerical simulations. In this Roadmap, we try to provide a broad overview of recent and potential future activities in the MG field, and present a roadmap for the development and applications of MGs by gathering contributions form scientists with diverse backgrounds, illustrating the major challenges and discussing the latest technology and strategy to tackle these challenges with experts covering various developments in general concepts, synthesis and characterisation, and theoretical and simulation methods.
