Abstract

See full text

A Cu—Al—Mn-based alloy rod having superelastic characteristics and having a recrystallized microstructure substantially formed of a β single phase, wherein, for a longitudinal direction cross section of the rod, a region, in which a grain size of each of grains is a radius of the rod or more, is 90% or more of the longitudinal direction cross section at any location of the rod, and wherein an average grain size of the grains, in which the grain size is the radius of the rod or more, is 80% or more of a diameter of the rod; a Cu—Al—Mn-based alloy sheet; a production method thereof; a vibration damping material using thereof; a vibration damping structure constructed by using the vibration damping material.
