摘要
形状记忆合金由于具有形状记忆效应等优良特性而被广泛应用。本文将形状记忆合金环装配至电力金具后,通过与普通材料进行多组拉力对比试验,得到了普通材料加装形状记忆合金环后的力学性能指标,并通过对拉力曲线的线形走势进行分析,证明了形状记忆合金环对缺陷金具的修复和改善作用,能够增强普通材料的力学性能,减小材料的变形。
Shape memory alloy is widely used due to shape memory effect and other excellent properties. In this paper, the shape .memory alloy ring is assembled to the electric power fittings. The mechanical properties of the common material with shape memory alloy ring were obtained comparing with the common material. Through the tensile curve of the linear trend analysis, the shape memory alloy ring of defective hardware repair and improvement demonstrate to enhance the mechanical properties of common materials and reduce the material deformation.
