Description
The fatigue properties of various steel cored bi-metallic wires, with aluminum, copper, and zinc as coatings, were tested to determine fatigue behavior as measured by a rotary bending fatigue test. On Al, Al alloy, and zinc clad wires the coating material had little or no effect on fatigue properties. The authors conclude that it is the clad metal which most influences the fatigue properties of bi-metallic wire, with residual tensile stress at the surface of the steel core playing the most significant role in influencing fatigue properties.
