Metallic glasses alloys are a relatively new class of materials characterized by the absence of structural long-range order. During heating, these alloys exhibit a glass transition at a temperature (Tg) before reaching the crystallization temperature (Tx). Within this temperature interval (ΔTx = Tx - Tg), they behave as a supercooled-liquid and their viscosity decrease around 6 orders of magnitude compared to the value observed at room temperature. This feature opens up possibilities for consolidation of atomized powders with amorphous structure when it is carried out within ΔTx. In this sense, the present work aimed to study the fabrication of bulk parts of Fe43.2Co28.8B19.2Si4.8Nb4 metallic glass by a combination of gas atomization and ho...
