The study of bulk metallic glasses (BMG) in multicomponent systems has aroused great scientific and technological interest, in recent decades, for its unique properties due to the lack of long range atomic order in the structure and compositional homogeneity similar to the liquid state. In this context, this master's project consists in characterizing thermally, mechanically and morphologically, two compositions of metallic glasses, aiming to identify the presence of complex or disordered bonds (amorphous structure). The results will be compared with literature information. To achieve this objective, we intend to use experimental techniques of characterization of materials to obtained greater reliability in the process of identification of the type of arrangement to which they are subjected to the atomic bonds of these compositions. The techniques that will be used in this project are: X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). All the equipment to be used belong of the infrastructure of Mackenzie Presbyterian University (UPM).This work is linked to the following projects: 1-) Thematic Project "Processing and characterization of amorphous, metastable and nanostructured metallic alloys", Process 2013/05987-8 - FAPESP, with Principal Investigator: Prof. Dr. Claudio Shyinti Kiminami/UFSCar and Prof. Dr. Odila Florêncio (UFSCar e UPM) as associate researcher. 2-) Project "Anelastic relaxation process associated to atomic migration and structural rearrangement in metallic alloys with high glass forming ability (glassy and nanocrystalline alloys)", Process 2013/13378-1 - FAPESP, Post-Doctoral Felowship (Paulo Wilmar Barbosa Marques) and Prof. Dr. Odila Florêncio (UFSCar e UPM) as supervisor. These two projects have Federal University of São Carlos (UFSCar) as host institution. The execution of this work will enable the interaction between these two institutions: UFSCar and UPM. (AU)
