sir<div>i am calculating the phase transition of some carbides</div><div>the transition from B1 to B2 transition occures at 130 gpa by enthalpy compparison </div><div>but i am able to find phonon instability at 130 gpa for B1 structure</div>
<div>but at the same time i am not able to find the dyanamic stability of B2 phase</div><div>but it occures high pressure (more than130 gpa )</div><div>is there any explanation for this ?</div><div><br></div><div>is there any relation of thermodyanamical unstability</div>
<div>and dyanamical unstability simultaneously?</div><div><br></div><div><br></div><div>answers are highly appriceted with some reson</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br>
