摘要：

Understanding and contemplating the structural stability of materials under extreme conditions is one of the active fundamental research areas that provide the most essential information about the stability aspects. In static compression experiments, the parameter of bulk modulus is considered a key factor in precisely knowing the stability of materials. However, under dynamic conditions, (acoustic shocked conditions), materials undergo phase transitions irrespective of their bulk moduli which leads to many open questions about the real-time structural stability of the materials. To provide firsthand information on the acoustic shock wave-induced phase transition ability of materials, herewith we have chosen three different bulk modulus carbon structures such as the tetrahedral amorphous carbon (ta-C), graphite and graphene materials such that their structural stability could be examined under different shocked conditions such as exposed to 0, 250, 500 and 750 shocks. Based on the Raman spectroscopy and X-ray photoelectron spectroscopic results, it is identified that ta-C has transformed into a highly ordered graphite at the 750-shocked condition, whereas the graphite and graphene structures do not undergo any structural transitions. For the first time in the literature, to date, we introduce the thermal conductivity parameter as a common key factor to explain the observed results under shocked conditions whereby it is found that materials of lower thermal conductivity can easily undergo the structural transitions whereas vice versa for the materials of higher thermal conductivity under shocked conditions. The graphite and graphene structures are stable under shocked conditions because of their higher thermal conductivity. The proposed approach is compared with the previously published results under shocked conditions thereby it is found to be well-matched with the current interpretation. According to the observed results, the structural stability order is as follows: ta-C < graphite < graphene such that the stability order of these three carbon structures is completely different while under static compression.
