摘要Modified many-body interatomic potentials for modeling high-energy atomic collision in NiAl are constructed and described. The displacement threshold energy as a function of the primary recoil direction for Ni atoms and Al atoms in NiAl has been investigated by molecular dynamics simulations using the modified potentials. The defect structure induced by recoil events has been presented. The results show that the lowest threshold displacement energy, E-d, is near the [100] orientation and the mean value of E-d for an Al atom is higher than a Ni. A crowdion in the compact crystalline directions, [1 1 1], incorporating an extra Ni atom is the stable interstitial configuration. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
