Shock wave induced order to disorder type phase transition of cobalt chloride hexahydrate doped l-histidine hydrochloride monohydrate single crystal

Abstract

The impact of supersonic shock waves upon materials is one of the fascinating areas of active research in material science. Phase transition behaviour of materials, when subjected to shock waves, is also of great interest in this field. In the present investigation, we have proved the impact of shock wave-induced order–disorder type phase transition of cobalt chloride hexahydrate doped L-histidine hydrochloride monohydrate single crystal. The test crystal was subjected to the corresponding shock pulse counts of 0, 1, 2, 3, and 4 with Mach number 1.7 until the third shock condition, there wasn't a phase change; however, in the fourth shocked condition, there was a phase transition of the order–disorder type noted. X-ray diffractometry, Raman spectroscopy, and UV–Visible spectroscopy are three different analytical techniques that have been used to confirm the aforementioned phase transitions. The order–disorder phase transition enables the investigation of novel aspects of a material's structural properties. The grown crystal had reacted to shock wave exposure in terms of the type of phase transition order–disorder.
