New multicomponent Ta-based glassy alloy powder was synthesized by mechanical alloying a mixture of elemental Ta<SUB>55</SUB>Zr<SUB>10</SUB>Ni<SUB>10</SUB>Al<SUB>10</SUB>Cu<SUB>15</SUB> 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 (<I>T</I><SUB>g</SUB>) lies at a high temperature (834 K), crystallize through a single sharp exothermic peak at 1004 K (<I>T</I><SUB>x</SUB>). The total enthalpy change of crystallization (<I>ΔH</I><SUB>x</SUB>) is −10.32 kJ/mol. The supercooled liquid region before crystallization (<I>ΔT</I><SUB>x</SUB>) of the synthesized glassy powder shows the widest value (170 K) of any reported metallic glassy system.
