Conclusions

The reason for the formation of longitudinal internal cracks during deformation of highly alloyed aluminum alloys is the concentration of elastic stresses in areas of the metal with the highest flow rate gradients. Complete relaxation as the result of recrystallization (in hot deformation) and plastic deformation is not possible because of the low ductility of the alloys, and therefore relaxation occurs partly by crack formation. These cracks begin, with the cracking of brittle inclusions in the metal.
