Abstract:
The model relating the polymorphic transformation of a crystalline substance under shock wave loading to the change in its elastic energy is further considered, now by an example of boron nitride. The results obtained show that the model provides a reliable description of the martensite phase transition in boron nitride subjected to a shock wave. It is found that the shock adiabat of boron nitride regardless of its structure has an inflection at the shock wave velocity $D\approx 6.2$ km/s. The nature of this inflection is not clear yet.
Keywords:
