Mechanical Properties of Copper-Nickel-Titanium Archwires

MECHANICAL PROPERTIES OF COPPER-NICKEL-TITANIUM ORTHODONTIC WIRES Margaret Rosen, D.M.D. Marquette University, 2016 Introduction: The initial phase of orthodontic therapy relies on flexible wires, usually composed of a nickel-titanium alloy, to apply a substantially constant load during tooth movement. Copper has been added to nickel-titanium archwires, resulting in an alloy with potential clin...

TRANSFORMATION BEHAVIOR OF NiTi SHAPE MEMORY ALLOYS TREATED BY THERMOMECHANICAL PROCESSING USING DSC

Abstract: In the present study the effect of thermomechanical treatment (cold work and annealing) on the transformation behavior of NiTi shape memory alloys was studied. Differential scanning calorimetry was used to determine transformation temperature and its relation to precipitates and defects. Three alloys including Ti-50.3at.% Ni, Ti-50.5at.% Ni (reclamated orthodontic wires) and 50.6at...

Thermal analysis of as-received and clinically retrieved copper-nickel-titanium orthodontic archwires.

OBJECTIVE To compare as-received copper-nickel-titanium (CuNiTi) archwires to those used in patients by means of differential scanning calorimetry (DSC). Also, the thermal or phase properties of 27 degrees C, 35 degrees C, and 40 degrees C CuNiTi archwires were studied to ascertain if their properties match those indicated by the manufacturer. MATERIALS AND METHODS Six wires of 27 degrees C, ...

Influences of Reduction Ratio on Mechanical Properties and Transformation Temperature of NiTi Drawn Wires

NiTi alloy wires are widely used in many applications for examples, orthodontic arch wires, mini screw implant, sensors, etc. Usually, wire drawing process is chosen to produce arch wires because of its high productivity as well as superior surface quality of the drawn wire surface. In the case of NITI arch wire, the cold work occurred during wire drawing operation also plays important role to ...

Flow Behavior of SP-700 Titanium Alloy During Hot Tensile Deformation in α+β and β Phase Regions

In this paper, in order to study the flow behavior and elongation of as-cast ingots of SP-700 titanium alloy, hot tensile test was done in α/β dual phase and β single phase regions using strain rate of 0.1 s-1. Results showed that the hot tensile behavior of SP-700 in the α/β dual phase region (700-900 ºC) was different from the β single phase one (950-1100 ºC) due to the nature of alpha and be...
