Abstract:  
A brief history on shot peening Shot peening is a metal surface treatment that can extend the fatigue life of most metals. Its ancestor is "hammering". Evidence of hammering a metal to shape and harden its surface can be traced back as far as 2700 B.C. to a gold helmet found at Ur (Mesopotamia).
