The UIT/UP produces a number of beneficial effects in metals and alloys. Foremost among these is increasing the resistance of materials to surface-related failures, such as fatigue and stress corrosion cracking. The fatigue testing of large-scale parts and welded specimens showed that the UIT/UP is the most efficient improvement treatment as compared with traditional techniques such as heat treatment, TIG-dressing, hammer peening and shot peening.
