Abstract: A fatigue-resistant Nitinol instrument has a working portion in the deformed monoclinic martensitic state and an austenite finish temperature in the range of 40° to 60° C. Because the operating environment of the instrument is about 37° C., the working portion remains in the monoclinic martensitic state during its use. The relatively high austenite finish temperature and fatigue resistance is achieved by subjecting the nickel-titanium alloy to a final thermal heat treat in a temperature range of about 410° to 440° C. while the nickel-titanium alloy is under constant strain of about 3 to 15 kg. Further, the high austenite finish temperature is achieved without subjecting the alloy to thermal cycling to produce shape memory. Additionally, there are no intermediate processing steps occurring between obtaining a finished diameter of the wire or blank through cold working and the final thermal heat treat under constant strain.

Abstract: A weld wire for storage on a spool of weld wire. The weld wire has a substantially linear cast in the form of an undulating curve that generally lies in a single plane. The undulating curve is a succession of generally semi-circular sections having a generally fixed radius of curvature. The linear cast is formed on the weld wire prior to the weld wire being wound on the spool of weld wire. The linear cast is at least partially retained on the weld wire after the weld wire is unwound from the spool and during the feeding of the weld wire through a welding machine.

Abstract: Method for manufacturing endodontic instruments having either helical or non-helical flutes. A method is provided for forming superelastic endodontic instruments having helical flutes, wherein a wire of superelastic material is formed into an instrument blank, and before twisting, the superelastic alloy is brought to an annealed state comprising a phase structure including a rhombohedral phase alone or in combination with austenite and/or martensite, or a combination of martensite and austenite. In this annealed state, the instrument blank is twisted at low temperature, for example less than about 100null C., and advantageously at ambient temperature to the final desired twisted configuration. The twisted instrument is then heat treated and rapidly quenched to a superelastic condition. A method is further provided for manufacturing endodontic instruments having either helical or non-helical flutes with hard surfaces and resilient cutting edges by either an EDM or ECM process, wherein material is removed from the instrument blank in the desired flute pattern. The EDM or ECM process disintegrates the surface material, and as it cools, at least a portion of the removed material re-deposits onto the surface being machined to form a recast layer having a surface hardness that is at least about 15% greater than the hardness of the material forming the instrument blank. A method is further provided in which an EDM or ECM process is used to form an instrument blank, followed by twisting at low temperature.
