摘要	A simple modified analytic EAM model for hcp Co and fcc Al metals is used to calculate the formation energies of vacancy and antisite of B2 CoAl and L1(2) Co3Al alloys. The point defect type is Al antisite defects for the Co-rich side and Co antisite defects for the Al-rich side in B2 CoAl. The point defect type is Al antisite defects for the Co-rich side and Co antisite defects for the Al-rich side in L1(2) Co3Al. The lattice constant and elastic constants are calculated. The present calculations are in qualitative agreement with the experimental data and the theoretical results obtained by other authors.; A simple modified analytic EAM model for hcp Co and fcc Al metals is used to calculate the formation energies of vacancy and antisite of B2 CoAl and L1(2) Co3Al alloys.
