“…Many studies [14,15,20,[22][23][24][25][26] were presented on the phase equilibria of the quasi-binary MoSi 2 -XSi 2 (X ¼ Ti, Ta, V, Cr, Nb) systems, from which the possibility of an equilibrium transition between the bMoSi 2 -C40 and the aMoSi 2 -C11 b polymorphic phases for pure MoSi 2 can be precluded.…”
