Fe-Ni-Ti-Cr alloy - Opis:
- The research comprises a discussion about a formation of intermetallic phase with stoichiometric composition Fe2Ti, called Laves phase, and influence of chromium on the whole structure containing this phase by means of comparison of the two alloys. A base Fe35Ni35Ti30 alloy was used as a reference and then compared with a Fe-Ni-Ti chromium doped - Fe30Ni35Ti30Cr5 alloy. The study of microstructure performed with scanning electron microscope enabled to distinguish different phases. These regions are rich in mixture of Fe-Ni and Ti-Ni elements. The identified phases are Fe2Ti and Ni3Ti which was confirmed by X-ray diffraction and simultaneously it is consistent with energy dispersive spectroscopy results. Differential scanning calorimetry confirmed also multi-phase composition. As a result different hardness was measured for these phases using nanoindentation. The overall hardness was established using the Vickers method.
