In the present work, Nb-Ti-Co phase diagram in the Nb-rich region was constructed by using CALPHAD method and Thermo-calc software, and then the solidification paths of 58 kinds of alloys were studied by using the uniform microsegregation model. The influences of solid back diffusion coefficient...
In recent years, the focus of research efforts towards these metal membranes has been the development of robust/cheaper alloys and the exploration of related phase diagrams. To address this challenge, the phase diagram and solidification path of the Nb-Ti-Fe alloy system have been investigated ...

The weight loss Therefore, the investigation on the phase diagram of this of the alloys after melting was less than 0.3 wt%. The 3 system is very significant. However, the phase diagrams slices (103833 mm ) were prepared from the ingot by determined in the earlier period were limited ...
The 12 single-phase regions include a-Ti solid solution, β-(Ti,Nb) solid solution,Ti2Ni,TiNi,TiNi3,fcc-(Ni) solid solution,Ni3Nb, Ni6Nb7, XA, XB, XC and XD. The ternary compound XB is discovered for the first time. Key words: Ti-Ni-Nb system phase diagram isothermal section ...
Combined with EDS analysis (Table 2) and Nb-Ti-Si phase diagram, the darker area consisted of Nb, Ti and Si elements (atomic ratio of (Ti + Nb): Si ≈ 5: 4), which was recognized to be (Ti,Nb)5Si4, while the lighter area was identified as (Nb,X)5Si3 (atomic ratio of (Nb...
