UUO.

Destruction for two halves of samples:

a) an unprocessed sample;

b) sample after UUO.

As the process of processed and unprocessed samples is removed from the place of destruction DC2, LMAX2, DC3, LMAX3, they change significantly. Fluctuations indicate the strong heterogeneity of the distribution of plastic deformation in the area of ​​the weld and zones
