COPPER BASE ALLOY HAVING SHAPE MEMORY CHARACTERISTIC AND SUPERELASTICITY, AND ITS PRODUCTION

Title:

COPPER BASE ALLOY HAVING SHAPE MEMORY CHARACTERISTIC AND SUPERELASTICITY, AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JP2000169920

Kind Code:

A

Abstract:

To produce a copper base alloy having high shape memory characteristics and superelasticity wile maintaining excellent workability.

This copper base alloy, which has shape memory characteristics and superelasticity and whose crystal structure is the recrystallized texture in which the crystal orientation of β single phase is arranged, is produced by executing forming by cold working including annealing, solution heat treatment, quenching and aging treatment, and the cold working is executed at the total working ratio after the final annealing so as to control the abundance ratio in the specified crystal orientation of the β single phase in the working direction measured by an electron back scattering pattern method to ≥2.0.
