| 中文摘要 | The ideal strengths of L1(2)Co(3)(Al,W) in comparison with Ni(3)Al are investigated using the first-principles method. Results for the stress-strain relationships, ideal tensile and shear strengths are presented. The calculated elastic properties agree well with the experimental observations. Co(3)(Al,W) is found to have larger moduli and higher strengths, but less ductile than Ni(3)Al. The electronic structures indicate the directional covalentlike Co-W bonding through d-d hybridization is the origin of excellent mechanical properties of Co(3)(Al,W). |
