Abstract

The laws of changing the shape of cylindrical springs made of a titanium nickelide-based alloy are considered as a function of the level of counteracting stresses and thermal cycling boundaries. Stresses from 20 to 110 MPa are shown to cause completely reversible deformation of the material; at higher stresses, unrecovered deformation accumulates. During thermal cycling, a decrease in heating temperatures in the range A_s–A_f and an increase in cooling temperatures in the range M_s–M_f are accompanied by a decrease in the reversible deformation of the material.

恒定外力作用下NiTi弹簧执行器的可逆变形

由镍基钛合金制成的圆柱弹簧的形状变化规律被认为是抵消应力水平和热循环边界的函数。在20 ~ 110 MPa的应力范围内，材料发生完全可逆的变形；在较高的应力下，未恢复的变形会累积起来。在热循环过程中，随着加热温度在As-Af范围内的降低和冷却温度在Ms-Mf范围内的升高，材料的可逆变形减小。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
