On the Formation of High Damping State and Optimization of Structure of Industrial Damping Steels

Industrial high damping steels based on the Fe - Al metallic system have been studied. The optimization of the crystalline structure of the industrial damping steels has been shown to be very important for the achievement of high mechanical properties including high fatigue resistance. In the same time the achievement of high damping properties strongly depends on the magnetic domain structure of the material and, consequently, on the heat treatment procedure.
