| description | PROBLEM TO BE SOLVED: To provide a cast iron material excellent in vibration damping capacity in which vibration damping capacity is increased and to provide a method for producing the same. SOLUTION: This cast iron material excellent in vibration damping capacity has a hyper-eutectic composition, moreover, in which many graphite and many fine pores are formed, and the porosity is set to 2.0 vol.% or more. In the method for producing the cast iron material excellent in vibration damping capacity, a producing stage in which molten metal having a hyper-eutectic composition is produced, an adding stage in which an aluminum series addition material is added to the molten metal, a holding stage in which the molten metal is held in a molten state after the addition of the aluminum series addition material and a solidifying stage in which the molten metal subjected to the holding stage is solidified are performed in succession to produce a cast iron material having a hyper-eutectic composition, moreover, in which many graphite and many fine pores are formed, and the porosity is 2.0 vol.% or more. Furthermore, the area ratio of pearlite can be increased by increasing the content of manganese in the matrix. |
