摘要：

Enhancement of thermal stability and glass forming ability in Ni60Nb40-xTax (x = 0, 3, 5, 10, 20 at%) alloys has been investigated. The crystallization temperature increases from 660degreesC in binary Ni60Nb40 amorphous phase to 721degreesC in Ni60Nb20Ta20 amorphous phase. The fully amorphous rod with diameter of 2 mm is fabricated in Ni60Nb30Ta10 alloy by an injection casting method. The compressive failure strength of the Ni60Nb30Ta10 bulk amorphous alloy is 3346 MPa.
