The load-deflection behaviour of a number of commercially available superalloy nickel-titanium orthodontic wires has been examined in three-point bending over the temperature range 5-50 degrees C. The loading and unloading curves and plateau regions are found to be closely related to temperature with the stiffness decreasing quite dramatically over a narrow temperature range. The position of this range depends on the material being tested as there are marked differences due to the differing processing methods of the manufacturer. Force values at mouth temperature can differ by 600 per cent for wires of the same nominal diameter made by different manufacturers.
在5至50摄氏度的温度范围内，通过三点弯曲试验研究了多种市售镍钛正畸合金丝的载荷-挠度行为。发现加载和卸载曲线以及平稳区域与温度密切相关，在狭窄的温度范围内刚度急剧下降。该温度范围的位置取决于所测试的材料，因为不同制造商的加工方法不同，存在显著差异。不同制造商生产的相同标称直径的正畸丝在口腔温度下的力值可能相差600%。
