Phase equilibria in the three-component
system nickel–chromium–tantalum at 1375 K
Abstract
The isothermic section of the phase equilibria
diagram of the Ni–Cr–Ta system has been constructed at 1375 K by means of the
methods of equilibrium alloys and existence of six three-phase equilibria g-Ni+b-Cr+a-Ni3Ta;
b-Cr+a-Ni3Ta+l; a-Ni3Ta+l+Ni2Ta; l+Ni2Ta+m; m+l+NiTa2è l+NiTa2+b-Ta has been established. It is shown, that both cubic, and
hexagonal modifications are indicated in Laves binary phase.
Key words: nickel, chromium, tantalum,
phase equilibria.
