SHOT MATERIAL AND SHOT PEENING METHOD

摘要

A method of shot peening a workpiece comprising projecting metal alloy particles at a workpiece wherein said metal alloy particles comprises Fe in combination with B, C, Cr and Nb, wherein the Fe is present at a level of greater than 50.0 atomic percent. The metal alloy particles have a Vickers Hardness (HV) of at least 1150 and an elastic modulus of greater than 200 GPa.
