Abstract:  
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
