摘要：

In copper-nickel alloys, the coefficient of thermal dilatation is a strong function of the composition. By a careful choice of the composition gradient and the heat treatment, tailored residual stress profiles can be generated. These profiles are determined by deflection measurements during electro-chemical removal of subsequent layers. The necessary functional relations between the original stress profile and the bending of the non-homogeneous sample are derived. In experiments with the chosen alloy system, residual stress values up to 85 MPa were attained.
