Peening Meaning: Definition, Examples, and Translations
🔨
peening
[ˈpiːnɪŋ ]
Definition
metal working
Peening is a mechanical process that involves the plastic deformation of a material's surface to improve its mechanical properties. This technique is commonly used to enhance the fatigue strength of metals by inducing compressive residual stresses. It is often employed in aerospace and automotive industries, as well as in the repair of metal components. The peening process can be accomplished through various methods, including shot peening, where small spherical media is blasted onto the surface, or hammer peening, where a tool is used to strike the surface directly.
Synonyms
hammering, shot peening, surface hardening.
Examples of usage
- The engineer recommended shot peening to increase the durability of the aircraft component.
- Hammer peening was applied to the metal frame to improve its resistance to fatigue.
- After welding, the parts underwent peening to relieve stresses.
- Using a peening technique can significantly enhance the lifespan of the machined parts.

Origin of 'peening'
The word 'peening' is derived from the action of peen, which refers to the portion of a hammer or tool that is used to apply force. The term itself can be traced back to the 15th century when it was used to describe the process of shaping metal. The technique gained prominence in industrial applications during the 19th century, particularly with the advent of more advanced manufacturing processes. The introduction of shot peening as a method for enhancing metal strength occurred alongside the growth of aerospace engineering in the mid-20th century. Since then, peening techniques have evolved and adapted to meet the demands of various industries, laying the foundation for modern metallurgical practices.
