NiTi alloy used in dental prosthetic fixators shows pseudoelastic behaviour and exhibits a great potential in dental and orthopaedic applications where constant correcting loads are required. In order to use such materials in dental prosthetic fixators, where the device is cyclically deformed, it is necessary to investigate the effect of the cyclic straining upon the transformation stresses and temperatures of the material. The aim of this work is to study the load cycling of a pseudoelastic NiTi shape memory alloy to be applied in the making of dental prosthetic fixators.
用于牙科修复固定器的镍钛合金表现出伪弹性行为，在需要恒定矫正负荷的牙科和矫形应用中具有巨大潜力。为了在牙科修复固定器（其中装置会发生循环变形）中使用此类材料，有必要研究循环应变对材料转变应力和温度的影响。这项工作的目的是研究一种用于制造牙科修复固定器的伪弹性镍钛形状记忆合金的负荷循环。
