Sintesi e caratterizzazione del vetro che forma la lega Fe57.75Ni19.25Mo10C5B8

This work is a part of the ground base of the ThermoProp project which is supported by the European Space Agency (ESA). The project started in 2001 with eight participating scientific groups from five European countries (France, Italy, Germany, United Kingdom and Sweden). This project is devoted to the measurement of thermophysical properties of different alloys and it is interested in solidification processes. The aim of the project is to combine classical thermo-analysis, such as calorimetry, dilatometry, drop method, surface tension and viscosity, with non-contact measurement methods based on electromagnetic levitation in ground-based laboratory and under reduced gravity conditions of the International Space Station. In the case of amorphous alloys, microgravity measurements allow to study extensively thermophysical properties of the undercooled liquid that determine the glass formation. In this framework, in my thesis I studied thermodynamic and kinetic properties for the amorphization of a Fe-based alloy. My main focus was to find a correlation between processing parameters and glass formation of Fe57.75Ni19.25Mo10C5B8 alloy.
