摘　　要：测定了液压件弹簧Ｔ９Ａ和纺织摇架弹簧１Ｃｒ１８Ｎｉ９钢在不同温度下的应力松弛曲线［１］，并对两者进行了比较，说明温度对Ｔ９Ａ弹簧应力松弛的影响，通过电镜（ＴＥＭ）观察研究了松弛过程的亚结构变化。提出了液压件弹簧稳定化的技术方案。The Curves of stress relaxation for hydro springs and spinning machine have been measured at the different temperatures.After compared the two kinds of curves,We have explained the effects of temperature and substructure transfarmation during stress relaxation of the springs. We have suggested the new technigues for the stability of the springs.
