DEVELOPMENT OF Fe-BASED METALLIC GLASS SHOT AMO-BEADS FOR PEENING WITH HIGH STRENGTH AND LONG LIFE

摘要

Application of bulk metallic glass was examined as the shot peening media reforming technology of the material, much attention is paid to in these days. The intensity of an object product becomes strong and the shot used in connection with this also serves as high hardness. However, in order that toughness might tend to have crushed the conventional high hardness projection material low, the problem of increase of cost and the increase in generating of waste had produced it. Therefore, we have tried to solve these problems by applying the metallic glasses as shot. We have paid attention to Fe-based 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.
