摘要

摘要针对多孔石墨在冲击中的多晶体转变，对之前提出的将石墨相变过程与物质弹性能量变化联系起来的模型进行了测试。结果表明，该模型可以合理地描述过渡区以外的实验结果，即在不同初始结构的样品的孔隙率变化范围相当大的情况下。研究还讨论了所研究的模型如何改变了目前关于冲击波中物质多态转变的热力学观点。

Shock-Wave Polymorphic Transition in Porous Graphite

Abstract

For the polymorphic transformation of porous graphite in the shock, the previously proposed model linking the process of graphite phase transition with a change in the elastic energy of a substance has been tested. It is shown that the model plausibly describes the experimental results outside the transition zone in a fairly wide range of changes in the porosity of samples with their different initial structure. It is discussed how the model under consideration changes the currently existing ideas about the thermodynamics of the polymorphic transition of matter in a shock wave.

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
