| Abstract | The ideal strengths of L1(2)Co(3)(Al,W) in comparison with Ni3Al 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 Ni3Al. 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). |
