Method for adjusting residual stress of semi-hard copper through static magnetic field

Abstract

The invention discloses a method for adjusting residual stress of semi-hard copper through a static magnetic field. A semi-hard copper sample is placed in the static magnetic field for static magnetic field treatment; according to the method, the semi-hard copper sample is subjected to static magnetic field treatment in the magnetizing chamber, and the residual stress of the semi-hard copper is regulated and controlled by using the static magnetic field provided by the superconducting magnet, so that material softening caused by an eddy current Joule heating effect of a pulsed magnetic field is avoided; the method adjusts the residual stress of the semi-hard copper by externally introducing the static magnetic field, and has the advantages of simple steps, high treatment efficiency, greenness, no pollution and the like.
