Abstract
New multicomponent Ta-based glassy alloy powder was synthesized by mechanical alloying a mixture of elemental Ta55Zr10Ni10Al10Cu15 powders at room temperature, using a low-energy ball mill. The glassy powders of the final-product (1080 ks) in which its glass transition temperature (Tg) lies at a high temperature (834 K), crystallize through a single sharp exothermic peak at 1004 K (Tx). The total enthalpy change of crystallization (ΔHx) is −10.32 kJ/mol. The supercooled liquid region before crystallization (ΔTx) of the synthesized glassy powder shows the widest value (170 K) of any reported metallic glassy system.
