Disk-shaped nickel plates processed by high pressure torsion were successfully joined by ultrasonic welding. Welding resulted in the grain growth which is uneven along the cross-sectional height of the welded specimen. The specimens showed a gradient microstructure with a grain size ranging from 3 μm in the lower plate to 6 μm in the upper one, along with a developed substructure, after the process of USW.

Figure shows experimental data on particle growth during isothermal annealing at 1300 °C as a time dependence of the average particle volume. For particles located at different distances from the sample surface, these dependences are approximated by straight lines with close angular coefficients (curves 1 and 2).
