The annealing at 700 °C for 50 h leads to noticeable changes of the carbide subsystem of low-activation high manganese austenitic steel. After solution treatment (ST) it causes precipitation of M23C6 particles along the grain boundaries and on the MC particles. Annealing of the cold-rolled (CR) samples leads to the formation of these particles at the microtwin boundaries.

There is an increase in coalescence efficiency with increasing droplet concentration. This is due to the fact that an increase in the concentration of drops leads to a decrease in the distribution of the distance between the drops of the emulsion, which favorably affects the process of convergence of the drops.

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).

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.
