Abstract:  
INTRODUCTION The aim of this mini-series is to cover the basic scientific principles of shot peening. Fundamental principles are presented together with relevant theoretical explanations. Shot particles themselves are an obvious starting point— without them we could not have shot peening. Shot particles have a set of properties that govern their suitability for specific peening operations. These properties include: shape, size, mass, chemical composition, elasticity, hardness, toughness, wear resistance and structure. Ease of manufacture is also very important for commercial viability.
