Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of metals and composites. It entails striking a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation. [1][2]

Jan 11, 2024 · Shot peening is a cold working process that alters the mechanical properties on the metal’s surface and creates a compressive residual stress layer. Its primary purpose is to prevent the spread of microcracks on a surface.

Shot peening, also known as shot blasting, is a cold work process used to finish metal parts to prevent fatigue and stress corrosion failures and prolong product life for the part. How Does Shot Peening Work? Shot peening works as a cold mechanical impact treatment accomplished by striking a ductile metallic surface with multiple high-velocity ...

Aug 7, 2023 · In this article, we’ll explore the fascinating world of shot peening, a process that enhances metal surfaces through high-speed projectile blasting. Get ready to discover how this innovative technique works its magic, from boosting fatigue resistance to improving wear and corrosion resistance.

Shot peening works by striking a surface with a shot (round metallic, glass or ceramic particle) with enough force to generate plastic deformation. When a group of shots impact the surface they generate multiple indentations, resulting in the component being encased by a compressive stressed layer on the metal surface.
