Abstract
An inventive process is provided for creating residual compressive stress at a surface of a structure without resort to custom mandrels and dangerous high-pressure fluids. The inventive process yields autofrettage of a structure such as a tube, gun barrel and the like, the structure having an outer surface and an inner surface.
