Abstract
For the purpose of developing interatomic potentials for the simulation of Cu-Zr amorphous alloys, determination of parameters in the modified embedded atom method (MEAM) potential is studied. It is found that the stability of crystal structure of alloy depends sensitively on the choice of the parameters of screening function. Because it is said that the first neighbor interaction concerning with the atomic radius is important to form the amorphous alloys, according to the feature of MEAM, it is expected that the MEAM potential has an advantage in studying systems far from a reference structures, such as amorphous alloys.
