并绕型NiTi SMA网状内支架的研制

Study of Parallel-Winding Type of Inner Network Support of NiTi Shape Memory Alloy

简要介绍了并绕型NiTi SMA网状内支架的结构特点和制作方法,给出了记忆型和超弹性支架材料的力学性能试验结果,并对影响支架性能的材料和工艺因素进行了较全面的讨论。

The preparation and structure feature of an inner network support which is made of NiTi shape memory alloy are described in this paper. The inner network support was parallelly wound. The tested mechanical properties of the NiTi material having the shape memory effect and superelasticity are given. Also, the factors of effecting on the performance of the support are discussed.
