V-HfV2-HfCr2-Cr phase diagram

The phase state of alloys of the particular V-HfV2-HfCr2-Cr system was considered from the liquidus temperature to 800 deg C. Account taken of the previously studied isothermal sections in the 1100-1900 deg C range and of the polythermal section HfCr2-HfV2, a spatial picture of the particular system V-HfV2-HfCr2-Cr was plotted and a diagram of mono- and nonvariant transformations in the system was given. Two polythermal sections of the system V-HfCr2 were plotted for a constant content of 10 at. % of Hf
