研究了Ni 60 Nb 40-xTax（x = 0，3，5，10，20at%）合金热稳定性和非晶形成能力的提高。晶化温度从二元Ni 60 Nb 40非晶相的660°C升高到Ni 60 Nb 20 Ta 20非晶相的721°C。采用注射铸造法在Ni 60 Nb 30 Ta 10合金中制备了直径为2 mm的非晶棒材。Ni 60 Nb 30 Ta 10大块非晶合金的压缩断裂强度为3346 MPa.
Enhancement of thermal stability and glass forming ability in Ni 60 Nb 40-x Ta x (x = 0, 3, 5, 10, 20 at%) alloys has been investigated. The crystallization temperature increases from 660°C in binary Ni 60 Nb 40 amorphous phase to 721°C in Ni 60 Nb 20 Ta 20 amorphous phase. The fully amorphous rod with diameter of 2 mm is fabricated in Ni 60 Nb 30 Ta 10 alloy by an injection casting method. The compressive failure strength of the Ni 60 Nb 30 Ta 10 bulk amorphous alloy is 3346 MPa.
