摘要：

A novel phenomenon, dynamic localized phase transformation (LPT) at stacking faults during deformation, has been observed in various Ni-base and Co-base superalloys and found to play a critical role in determining the creep performance of these alloys. In this article, we review recent experiment observations of LPT, thermodynamic analysis on the fundamentals of LPT, first-principles calculations to link LPT to mechanical deformation, and computational tools and databases required to predict LPT. We discussed the generality of the LPT phenomenon, various challenges in quantitative predictions of LPT, LPT-strengthening and LPT-softening, and opportunities offered by the LPT mechanism in the design of the next generation of LPT-strengthened superalloys.
