摘　　要：结合0Cr18Ni9Ti不锈钢丝的组织性能及金属橡胶冷压成型工艺特征的分析,探讨了回火对0Cr18Ni9Ti金属橡胶构件物理及力学性能的影响。结果表明:回火可显著提高金属橡胶构件的承载能力并改变其恢复力曲线的变化特征,但对金属橡胶构件的阻尼损耗能力几乎没有影响。另外,经回火处理的金属橡胶构件宏观结构尺寸也发生了变化,对其初始设计尺寸造成了一定影响。因此,金属橡胶构件应在综合考虑回火对其力学性能和宏观结构尺寸影响的基础上确定回火温度,但一般不宜超过500℃。Combined with the analysis on microstructure performance of 0Crl8Ni9Ti stainless steel wire and cold-press molding process characteristic of metal rubber component, the effects of tempering on physical and mechanical properties of 0Crl8NigTi metal rubber component were discussed. The results show that the bearing capacity is improved and the restoring force curve characteristic of the metal rubber component is changed by tempering temperature, while energy dissipation capacity is less affected. The macro-structure dimension of tempered component is changed, and has a certain influence on its initial design size. Therefore, the tempering temperature of metal rubber component is determined on the base of considering the effects of tempering on the mechanical property and micro-structure dimension, but generally should not exceed 500 ℃.
