| Abstract Scope |
As an emerging class of materials with desirable attributes for many applications, one major challenge facing metallic glasses is the fact that they undergo the glass transition and crystallize at temperatures far below the liquidus temperature. This means that metallic glasses are typically not desirable for high-temperature applications as these transitions cause them to lose the beneficial properties of the glassy state. In this work, new ternary TaNiCo metallic glass compositions were predicted through a genetic algorithm method. Metallic glass powders were then produced through arc melting and gas atomization. A wide range of compositions in this alloy system were found to produce X-ray amorphous powder with the glassy phase stable up to 650°C. Crystallinity of the metallic glass powder was found to increase with particle size. In addition to high-temperature stability, these metallic glass powders exhibit high hardness and are promising candidates for many applications involving extreme environments. |
