| Abstract: | Hardness is an important index to measure aging degree of the materials. Aiming at change of T92 ferrite steel＇ s hardness after high temperature aging, a detail experimental research and analysis were made in this paper; the change reason of hardness was summarized. The paper has also discussed a new method to extrapolate creep - life based on the hardness, and extrapolated the creep - life of T92 steel combine with experimental data. |
