Vl. Solozhenko et Vz. Turkevich, hBN reversible arrow cBN equilibrium line calculated from experimental data on the cBN-to-hBN transformation to 1.4 GPa, HIGH PR RES, 16(3), 1999, pp. 179-185
In the pressure range from 0.3 to 1.4GPa, the onset temperatures of cBN-to-
hRN transformation have been found by quenching method on high-purity singl
e crystals of cubic boron nitride. From the experimental data with allowanc
es made for the kinetics of solid-phase transformation. the hBN reversible
arrow cBN equilibrium line has been calculated, which fits well with the eq
uilibrium phase p, T-diagram of boron nitride.
