摘要
The energy and elastic constants C (11), C (12), and C (44) as a function of particle size for Ni-Al intermetallic nano-particles are investigated by using embedded-atom method. We find that for nano-particles of large size, the size-dependent change in C (12) is slightly different from those in C (11) and C (44), which is attributed to the internal strains. We also find that for the nanoparticles of size larger than 2.5 nm, the calculated C (11), C (12), and C (44) of 1.52, 0.88 and 0.77 eV/(3) are in agreement with the available experimental results.
