SUPERELASTISCHES BAUELEMENT AUS EINER KUPFERLEGIERUNG UND VERFAHREN ZUM EINPRÄGEN UND KONSERVIEREN EINER KRÜMMUNG VORGEGEBENER GEOMETRIE

摘要

In a method of bending a rod- or rod-like unfinished workpiece of a single crystal material of a Cu alloy the workpiece is bent at an elevated temperature so as to provide for a predetermined curvature and then the workpiece is further heated whereby the curvature is established but the superelasticity is lost, the workpiece is cooled down and then tempered at another raised temperature for at least one hour and is then immediately quenched in a cooling medium.
