Abstract

The strength and plastic properties and the shape memory effect and superelasticity parameters of thin (30–90 μm in diameter) TiNi-based filaments have been investigated. The strength properties of the filaments are found to increase when the filament diameter decreases from 90 to 30 μm, and the plastic properties decrease in this case. The parameters of the two-way shape memory effect of the ultrathin nickel–titanium filaments depend on the size factor. The thin TiNi-based filaments are shown to exhibit high superelastic properties, and the maximum superelasticity temperature depends on the size factor.

尺寸因子对TiNi基薄丝的强度和塑性，形状记忆效应和超弹性的影响

摘要

已经研究了细的（直径为30–90μm）TiNi基长丝的强度和塑性，形状记忆效应和超弹性参数。当细丝直径从90μm减小到30μm时，发现细丝的强度特性增加，并且在这种情况下塑性特性降低。镍钛超细丝的双向形状记忆效应的参数取决于尺寸因子。TiNi基细丝显示出高超弹性，最大超弹性温度取决于尺寸系数。
