Ornament and method of manufacturing the same.

摘要

An ornament is disclosed, which is characterized in that a metallic alloy wire provided with a characteristic to show the superelastic effect at room temperature by making the metallic texture Austenite phase is overlapped on both ends and formed into an approximately circular ring shape to form a wound ring. A method of manufacturing the same claimed is that a prime wire of Ni-Ti type alloy is submitted to the cold processing rating from 20 to 50 % to form a round or angular wire rod, said wire rod is wound up around a stick or pipe with a fixed outer diameter and submitted to the heat treatment at 300 to 600 DEG C under restraint of both ends of wire rod to form a wound ring of approximately circular ring shape and simultaneously the superelastic effect is given to said ring at room temperature by making the metallic texture thereof Austenite phase.
