- 1811 Ab-initio Lattice Instability Analysis on Ni and Ni_3Al Single Crystals under Pure Shear
説明
The "ideal strengths" of Ni and Ni_3Al single crystals under [100] (001) shear are discussed from the viewpoint of the lattice instability. Change in the elastic stiffness coefficient under shear is calculated by using the Vienna Ab-initio Simulation Package (VASP) with the generalized gradient approximation (GGA) and ultrasoft psudopotentials, and stability of lattices are evaluated on the basis of their positiveness. Both Ni and Ni_3Al become unstable at the strain of 0.21. We added these results to the "yield curve" of Ni and Ni_3Al against uniaxial tension/compression and hydrostatic tension, proposed in our previous study.
