微秒到秒时间尺度的高压相变动力学和物性研究:回顾、进展及展望OA北大核心CSTPCD

In recent years,the development of rapid loading techniques(such as dynamic diamond anvil cell,dDAC)and time-resolved detection technologies based on diamond anvil presses has opened up new research directions in high-pressure science.This involves exploring the evolution of material structures and physical properties under pressure(or over time)in high-pressure non-equilibrium physical processes that lie between static high-pressure and shock-wave experiments in terms of time scale and loading rate.By reviewing and summarizing the rapid loading and time-resolved probe techniques that have emerged in recent years,this paper attempts to think about and generalize high-pressure science issues and technical challenges on the microsecond to second time scale.It starts from aspects such as structure phase transition dynamics that depend on loading rate,phase transition pathways,the formation of metastable phases,microstructures,and mechanoluminescence,aiming to provide some inspiration and reference for researchers in this field.
