| Abstract: | The constitution of the ternary systems V–Fe–N, V–Co–N, and V–Ni–N has been investigated by X-raymethods, metallographically and partly by microprobe analysis. Isothermal sections are presented for 1100°C and 1200°C respectively. Ternary complex nitrides have been observed in the systems V–Co–N and V–Ni–N. The compounds with formula V4Co2N (a=10.88–10.83±0.01 Å) and V4Ni2N (a=10.88–10.86±0.01 Å) crystallize with the partly filled Ti2Ni-structure.
