Annotation The results of neutron diffraction study of VC0.47 are presented and discussed. It is established scheme of the phase transitions. A low temperature orthorhombic ordered phase (space group Pbcn) and high temperature hexagonal ordered phase (space group P6322) exists in VC0.47. The kinetic of the transition is described by Kolmogorov – Johnson – Mehl – Avrami law.
