REVIEW SOME OF NON-DESTRUCTIVE METHODS FOR PHYSICAL AND MECHANICAL CHARACTERISTICS TESTING OF THE MATERIAL OF ROCKET BARRELS AND ARTILLERY SYSTEMS
Barrels of missile and artillery systems during intensive operation are exposed to high temperatures, alternating loads, and corrosive aggressive environments. These effects lead to rapid degradation of the metal, changes in its structure, the appearance of intergranular corrosion, microcracks, and changes in the physical and mechanical properties of the material as a whole. The combined effect of the above factors leads to the inability of the structure to withstand operating parameters and its rapid destruction.
