i am calulated b1 to b2 transition of some metal carbide <div>i found b1 to b2 transition at 140 gpa</div><div>from phonon dispersion i found dyanamical unstabilty at 140 gpa b1 phase but i am also</div><div>found b2 is dyanamical unstable(in X and M) directions so i thought there must be other phase which may be stable at 140 gpa</div>
<div>for this calculated L10 phase which will less enthalpy than b2 at 140 gpa but also this shows imaginary frequency in X direction</div><div>so what is the stable phase?</div><div><br></div><div><br></div><div><br></div>
