Abstract

Enhancement of thermal stability and glass forming ability in Ni ₆₀Nb_40-x-Ta_x (x = 0, 3, 5, 10, 20at%) alloys has been investigated. The crystallization temperature increases from 660°C in binary Ni₆₀Nb₂₀ amorphous phase to 721°C in Ni ₆₀Nb₂₀Ta₂₀ amorphous phase. The fully amorphous rod with diameter of 2 mm is fabricated in Ni₆₀Nb ₃₀Ta₁₀ alloy by an injection casting method. The compressive failure strength of the Ni₆₀Nb₃₀Ta ₁₀ bulk amorphous alloy is 3346 MPa.
