Isothermal cross section of phase diagram of Ti - TiN3 - Mo system at 900 deg C

By the results of metallographic and X-ray phase analyses isothermal cross section of phase diagram of the Ti-Ni-Mo system in the field of Ti-TiNi3-Mo at 900 deg C is plotted. Solid solutions β on the titanium and molybdenum base co-exist with eta-, delta and epsilon-phases on the base of binary compounds Ti2Ni; TiNi and TiNi3, respectively forming two-phase and three-phase regions β+eta, β+delta, β+epsilon, β+delta+eta, β+delta+epsilon. Phase homogeneity regions on the binary compounds base in the ternary compounds system are not wide, molybdenum solubility in TiNi, TiNi3 and Ti2Ni constitutes 8, approximately 3 and < 2 at.%, respectively. Ternary phases in the investigated region of the Ti-Ni-Mo system at 900 deg C are not revealed
