In this study, the influence of two nanoscale parameters (e.g., ratios of energy and width of two different interfaces) and temperature have been investigated which drastically affects the formation of interfacial melt during solid-solid phase transformations in energetic Octogen crystal. For different critical values of these parameters and depending on the energy barrier of the solid-melt interface, the appearance of propagating interfacial melt can be either continuous-reversible without the hysteresis or jump-like first-order discontinuous transformation with hysteresis. It is found that these nanoscale parameters significantly affect the phase transformation mechanism, induces different scale effects, and changes the nanoscale behavior of octogen crystal.

在这项研究中，已经研究了两个纳米级参数（例如，两个不同界面的能量与宽度之比）和温度的影响，这极大地影响了高能Octogen晶体在固-固相变过程中界面熔体的形成。对于这些参数的不同临界值，并取决于固体熔体界面的能垒，正在传播的界面熔体的外观可以是连续可逆的，而没有滞后现象，也可以是具有滞后的跳跃状一阶不连续转变。发现这些纳米级参数显着影响相变机理，引起不同的尺度效应，并改变八聚体晶体的纳米级行为。
