摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a damping material for machine parts, capable of introducing a non-bonding interface in a small number of processes.
SOLUTION: The method includes the steps of: preparing a preformed material 2a having a first thick-walled part 4a with a first projection 5a, a thin-walled part 6 and a second thick-walled part 4b adjoining the first thick-walled part 4a with the thin-walled part 6 interposed between them; arranging the preformed material 2a between a pair of dies 3a, 3b regulated in expansion of an outer diameter shape perpendicular to a pressing direction; plastically deforming metallic material forming the first thick-walled part 4a and the second thick-walled part 4b by subjecting the material to forging while applying it pressure to narrow a space between the pair of dies 3a, 3b, so that the metallic material flows into the thin-walled part 6 and the surface of first thick-walled part 4a and the surface of the second thick-walled part 4b contact with each other; and forming the non-bonding interface 7 at which the first thick-walled part 4a and the second thick-walled part 4b contact without forming metallic bonding in a state of laying the thin-walled part 6 inside.

摘要： PROBLEM TO BE SOLVED: To provide a vibration damping material for a machine component, capable of easily selecting a material according to a demand with few restrictions in respect of the material, being widely applied to many machine components, and easily achieving further excellent vibration damping characteristics.
SOLUTION: A ringl-like material 2 having a groove portion 21 formed by a plastic working and/or machining has nonbonding interfaces which are in contact with each other without being metallically coupled to each other, and which are formed by a method for performing the plastic working by a ring rolling working which performs rolling in a direction where the material 2 is radially extended and also a space in the groove portion 21 is reduced. The nonbonding interfaces are formed from a surface to a predetermined depth in an inside, and it is preferable that they do not penetrate through. It is preferable that the length of the nonbonding interfaces in a depth direction is set to be 20% or more of thickness dimension in the same direction.
