摘要: 本文测定了不同温度下弹簧应力松弛曲线,拟合了松弛曲线方程。利用透射电镜观察了松弛前后的弹簧材料的TEM组织变化。认为应力松弛过程是位错排列趋向均匀规整,应力和亚结构趋向均匀过程。

Abstract: The curves of stress relaxation at 25℃, 80℃, 160℃ and 240℃ have been measured, according to testing data we have analogized the equation of the curves. Because of this curves varing, the structure transites of material have been observed by means of TEM and SEM. So that we supposed that process of stress relaxation is that the dislocations translate into regularity and stress changes in to homogeneous.
