New paper in the Journal of Non-Crystalline Solids

The members of the Group of Characterization of Materials (GCM) have published a new paper in the Journal of Non-Crystalline Solids entitled “New (FeCoCrNi)-(B,Si) high-entropy metallic glasses, study of the crystallization processes by X-ray diffraction and Mössbauer spectroscopy”. In this paper their produce for the first time a new family of high-entropy metallic glasses, a kind of materials that combine the properties of high-entropy alloys and metallic glasses. They have potential use in industrial applications due to their outstanding mechanical properties, such as excellent wear resistance, high strength and exceptional ductility. However, their application depends on a detailed knowledge of their microstructure and how it evolves after particular heat treatments. This papers characterize the crystallization route of this family of alloys using Transmission Mössbauer Spectroscopy together with X-ray diffraction and Scanning Electron Microscopy opening the possibility to tailor their microstructure and to optimize their properties by applying appropriate thermal treatments
