Abstract
An isothermal section at 1,100°C and at nitrogen pressures in the range of 1 to 300 bar of the system Ta-Mo-N has been examined by X-ray techniques. The composition range of the ternary Z-phase TaMoN has been investigated with respect to nitrogen content and metal composition. A new ternary phase was found at a composition of Ta3MoN3+x.
Within the δ-Mo2N-phase up to 25% of the Mo-atoms can be replaced by Ta-atoms at nitrogen pressures of 300 bar, while only a small amount of the Taatoms can be replaced by Mo-atoms within the Ta-nitrides up to nitrogen pressures of 300 bar. Up to about 50% of the Mo-atoms can be substituted by W-atoms within the Z-phase.
