Application of bulk metallic glasses was examined as the shot for the peening, which, as a reforming technology of the material, much attention is paid to in these days. As the strength of target products of peening is becoming higher, the shot is also demanded to be made of high hardness. The conventional shot has low toughness and is easy to be crushed. It has led to problems of increase in cost and waste. Therefore, we have tried to solve these problems by applying the bulk metallic glasses as shot. We have paid attention to Fe-base metallic glass system, and have searched for and found the best composition with high hardness and high toughness. Spheroidal particles made with the Fe-base metallic glass were used as shot for peening, and it was proved that this is of high hardness together with a long-life. Thus, we could develop new shot material for peening. We report details of development, and the characteristic when Fe-base metallic glass is applied to the shot for peening.
