Abstract:  
In the Winter 2018 issue of The Shot Peener, we discussed two non-conventional peening techniques—one of which was Vibratory Peening. In addition to the superior surface finish, we learnt that the layer of compression was deeper with vibratory peening when compared to conventional shot peening. The process itself was significantly different from conventional peening in terms of media life, dust generation and utility costs. We concluded that this technique of generating residual compressive stress was worth further exploration. The results are discussed here.
