Phase Separation in Metallic Glasses: Design, Phase Stability and Properties

The study of phase-separated metallic glasses (MGs) is motivated by both scientific curiosity and their potential practical applications. They offer insights into the behavior of disordered materials and open new avenues for designing advanced materials with tailored properties. Phase-separated MGs exhibit unique structural and physical characteristics that distinguish them from monolithic MGs. Moreover, they offer a unique opportunity to design composites or alloys with hierarchical microstructures across different length scales. Many efforts have been undertaken to understand the origin of phase separation in MGs; yet the understanding of the mechanism remains insufficient. The main disadvantage of monolithic MGs utilized in biomedical applications is their poor global room temperature plasticity and the limited availability due to the presence of elements with high toxicity. Thus, it is important to develop new phase-separated MG systems that not only can improve the mechanical performance but also provide candidates for biomedical applications to acquire desirable combination of properties. This project aims to synthesize new MGs by proper alloying addition, aiming to understand the genesis of phase separation. The effect of alloying addition on phase separation and properties will be investigated. Such studies will help to understand the structure (microstructure)-property co-relations in these alloy systems. The results of these investigations will be used as a guideline to modify the synthesis process to accomplish the main objectives, namely to obtain materials with desired properties. Novel dual-phase MGs will be designed with suitable mechanical properties for biomedical applications. In addition, we will explore the possibility of fabricating nano-porous network structure in phase separating MGs, which has the potential for various engineering applications. It is believed that this research will bring a significant impact for Europe to have a leading position in science, and for the researcher to have an excellent career development.
