| 概要 | Slip motion of a screw dislocation in a bee lattice under shear stress was simulated and analyzed using an atomicrow potential (two dimensional calculation) and Johnson potential (three dimensional ca...lculation) for three typical direction of shearing, i.e., x=-30° (twinning direction), x=0°and x=30°(anti-twinning direction). In the case of an inter-atomicrow potential yield stresses were obtained as 3 × 10＾＜-3＞, 4 × 10＾＜-3 ＞and 28×10^＜-3＞μ for the above three directions, respectively (𝛼=O) and 23×l0＾＜-3＞, 21×10＾＜－3＞ and 26×l0＾＜-3＞μ for 𝛼=0.1. Slip planes obtained in these calculations were twinning (112) plane, except the antitwinning stressing in a=0.1, where (101) slip was activated. For these two types of potentials metastable configurations at half an atomic distance were not obtained and the stable続きを見る |
