CU-AL-MN BASED ALLOY MATERIAL EXHIBITING STABLE SUPERELASTICITY AND MANUFACTURING PROCESS THEREFOR

摘要

A Cu-Al-Mn-based alloy having superelastic characteristics and having a recrystallized texture substantially formed of a ² single phase, in which 70% or more of crystal grains is within a range of 0° to 50° in a deviation angle from <001> orientation of a crystalline orientation measured in a working direction by electron back-scatter diffraction patterning.
