摘要

不连续析出物（DPs）的生长对合金的强化至关重要。我们的研究表明，由于孪晶效应，非连续析出物在晶界处成核，并沿孪晶和堆积断层的（1 1 1）方向生长。此外，生长速度还受到晶界润湿的影响。它重述了 DPs 的演化过程，并提供了操纵孪晶和堆积断层的策略。

Understanding the growth of discontinuous precipitates in a Ni-45%Cr alloy driven by twins and stacking faults

The Growth of discontinuous precipitates (DPs) is crucial in alloys that are strengthened by the DPs. Our research has demonstrated that DPs nucleate at grain boundaries and grow along twins and stacking faults in the (1 1 1) direction as a result of the twinning effect. Moreover, the growth rate is influenced by the wetting of grain boundaries. It restates how DPs evolute and provides a strategy by manipulating twins and stacking faults.
