Abstract:  
THE STRESSONIC®, Ultrasonic Shot Peening (USP)process is similar to conventional shot peening (CSP) in that it is a cold-working surface treatment. Both use media to impact the surface of a mechanical part, generating a compressive residual stress layer and improving material mechanical properties. Both enhance fatigue life and resistance to stress corrosion cracking.
