I have been asked on several occasions about the substitution of media. If one substitutes ceramic bead for glass bead (same size and propelled at velocity to achieve same intensity)will you get the same peening benefit?
Also, if you substitute cut wire media for cast steel shot, such as CW14 for S-110, using same hardness, can you expect to get equivalent peening results?
In short, if you deliver media at the same intensity (Almen saturation curve etc) or if you get a certain size dent from one media and then get the same size dent when using another media can you expect that the target material and therefore the peening benefit will be equal?
