Atomic simulations on the deformation mechanisms in nano-crystalline Ni–Al series Ni-based superalloy based on grain size, strain rate and temperature

Atomic simulations on the deformation mechanisms in nano-crystalline Ni–Al series Ni-based superalloy based on grain size, strain rate and temperature

Molecular Dynamic (MD) simulations were used to investigate the tensile properties of nanocrystalline Ni–Al series Ni-based superalloy at different grain sizes (6.54–20 nm), strain rates (1 × 107–5 × 108 s−1) and temperatures (300–1000 K). Results indicate that plastic deformation of nanocrystalline...
