A method for the construction of initial atomic models of nanocrystals with extrinsic dislocations in grain boundaries for molecular dynamics simulations is developed. The method is used to determine atomic structures and energies of grain boundaries in columnar f.c.c. nanocrystals with [112] column axis.

The recrystallization mechanism after ECP was deduced to be similar to that operating during conventional static annealing. The microstructural changes were explained in terms of Joule heating and similar observations for static recrystallization.

Hatching distance effects on microstructure of additively manufactured specimens. Increased hatching distance speed up the manufacturing process, but the porosity level also increases. Reduced hatching distance results in overheating and bubbling of the printed material.
The small distance between parts during manufacturing can compensate the increased hatching distance.

Effect of the hatching strategies on mechanical properties and microstructure of SEBM manufactured Ti-6Al-4V specimens

The combined treatment DCAP + aging 400°С + SPD by friction of the Cu–0.09Cr–0.08Zr SMC alloy gives rise to the friction-induced nanocrystalline structure with grains 15– 60 nm in size in the surface-layer material, which provides a high level of the microhardness and satisfactory tribological properties.
