Introduction
Air-blast shot peening is well-established as the principal technique employed for precision peening. Shot particles are accelerated by a stream of compressed air fed into a
nozzle. The maximum velocity of the air stream in the nozzle is the speed of sound, which is about 340ms-1 at 20°C. Particles can be introduced into the air stream by any
one of three techniques: suction-, gravity- or direct-feeding. Induced shot velocities are normally up to about 100ms-1.
