摘要/Abstract

摘要： 为了揭示1Cr18Ni9奥氏体不锈钢螺旋压缩弹簧的抗应力松弛性能优异的主要原因,在100、140、180和220 ℃下分别对弹簧进行了长达960 h的应力松弛试验。结果发现,经过松弛试验后,弹簧的自由长度变化较小。松驰温度为100 ℃时,在松驰过程中一阶段和二阶段间的拐点相较于其他松驰温度不明显,这是由松驰机理不同所导致的。此外,1Cr18Ni9奥氏体不锈钢螺旋压缩弹簧在100 ℃松弛时的塑性变形方式以位错的多滑移为主,而在更高的温度则以多滑移和孪生的方式发生塑性变形。

Abstract: In order to find the main reasons for the excellent resistance to stress relaxation of helical compression spring made of 1Cr18Ni9 austenitic stainless steel, stress relaxation tests at 100, 140, 180, and 220 ℃ were carried out. It is found that the free length of the spring changes little after relaxation test, butthe inflection point between the first stage and the second stage is not obvious during the process of relaxation at 100 ℃, which can be attributed to the difference in relaxation mechanism at different temperatures. Besides, the plastic deformation in 1Cr18Ni9 austenitic stainless steel helical compression spring is mainly multi-slip of dislocation under 100 ℃, but the plastic deformation occurs in a combination way of multiple slip and twinning at elevated temperatures.
