Synthesis of Cu47Ti34Zr11Ni8Bulk Metallic Glass by Warm Extrusion of Gas Atomized Powders
Abstract
<jats:p>Cu<jats:sub>47</jats:sub>Ti<jats:sub>34</jats:sub>Zr<jats:sub>11</jats:sub>Ni<jats:sub>8</jats:sub>amorphous gas atomized powders were consolidated by warm extrusion. After consolidation near 723 K using an extrusion ratio of 5, the material retains between 88% and 98% of the amorphous structure found in the gas atomized powder. The onsets of the glass transition and crystallization temperatures of this extruded material are observed respectively at slightly higher and lower temperatures than those of the starting powders. These temperature shifts are attributed to a composition change in the remaining amorphous phase during partial devitrification throughout the extrusion process. Powders extruded at the same temperature, but using higher extrusion ratios of 9 and 13, exhibit substantial devitrification during the consolidation process yet still deform homogeneously.</jats:p>
