| Popis: | First-principles calculations were employed to analyze the possible slip systems in Mo 5 SiB 2 . A striking result was obtained that the three most favorable slip systems, (001), (001) and [001]{010}, have close stacking fault energies, and the preference among them cannot be established. This finding explains a large variety of experimentally observed slip systems in Mo 5 SiB 2 . The dislocations associated with these slip systems may dissociate into partials joined with stacking faults and separated by the large splitting width of 5–6 nm. |
