鋳鉄の減衰能, 引張強さ, ヤング率に及ぼす黒鉛及び基地組織の影響 Effects of Graphite Morphology and Matrix Microstructure on Damping Capacity, Tensile Strength and Young's Molulus of Casting Irons
One of the main advantages of casting irons is its high damping capacity. However, any attempt to improve damping capacity generally leads to a decrease in the tensile strength. In this paper, the effect of modified graphite morphology and matrix microstructure on the damping capacity has been studied in order to improve the damping capacity. An increase in the carbon equivalent promotes the precipitation of long and coarse graphite flakes. This improved the damping capacity, while the tensile strength decreased. An austempering treatment, which produced ausferritic matrix structure, was found to improve the damping capacity without sacrificing the tensile strength.
