研究的热强化处理主要是以“多边化强化”处理对1Cr18Ni9Ti钢蠕变性能的影响，探讨了“多边化强化”工艺可有效地改善1Cr18Ni9Ti钢的蠕变性能，大大地减小其蠕变变形量和残余变形量，特别是能显著减小蠕变第一阶段的变形量，同时缩短蠕变第一阶段的时间。多边化处理后，碳化物的析出及完整、稳定的亚结构的形成是1Cr18Ni9Ti钢蠕变强度提高的本质原因。
The study of the thermal strengthening treatment is mainly based on “multilateralization strengthening ” effect on the creep properties of 1Cr18Ni9Ti steel, “Multilateralization ” process can effectively improve the 1Cr18Ni9Ti steel creep performance, greatly reduced Its creep deformation and residual deformation, in particular, can significantly reduce the deformation of the first phase of creep, while reducing the first phase of creep time. After the multilateral treatment, the precipitation of carbides and the formation of complete and stable substructures are the essential reasons for the creep strength of 1Cr18Ni9Ti steel.
