Document Type and Number:
Japanese Patent JP2010090465
Kind Code:
A
Abstract:
To provide a damping alloy material combining the properties of a vibration damping coefficient of 20% or more and a tensile strength of 1G Pa or more, and to provide the damping alloy material as an automotive vibration absorbing material.
The damping alloy material is an Fe-Al-Ni alloy material comprising each of Al and Ni at concentrations in the range surrounded by points A, B, C, D and E in Fig.1 and excluding the line segments of AB, BC, CD, DE and EA, and the balance Fe.
