Conclusions

  1. 1.

    The supersaturated solid solution comprising the major part of the cast metal in alloys VN3 and VN4 tends to decompose at 1000–1500°C.

     
  2. 2.

    Heat treatment conditions were established for alloys VN3 (1400°C for 3–5 h) and VN4 (1500°C for 3 h+1300°C for 10 h) ensuring overaging of the cast metal and a substantial increase of the ductility and workability.
