摘要：
The process of the quenching Ni-Co alloy prepared by melt-spinning technology is simulated by molecular dynamics simulation, and the structure characteristics of Ni-Co alloy are studied at different cooling rates. The simulation shows that, the alloy solidification process is sensitive to the cooling rate, and the formation of binary Ni-Co amorphous structure needs a high cooling rate above 80 K/ps. Add additional elements can reduce the required cooling rate of the materials. The alloy is completely crystalline at the cooling rate of 75 K/ps, and the structural change happens, especially at 375 K.
