Iron nickel phase diagram. The Cu-Ni phase diagram [ 2007Tur] depicts a continuous fcc solid solution between Cu and Ni. The solid solution breaks into Cu-rich and Ni-rich fcc phases at low temperatures. The Fe-Ni phase diagram [ 1991Swa] is characterized by a very narrow solidification range, with a peritectic reaction between (δFe) and liquid yielding (γFe). Schematic phase diagrams of iron-nickel system at the pressure of the inner core boundary. (a) If the Ni content in the outer core is less than that of the fcc-hcp-liquid triple point, the inner core could be composed of the hcp phase.

Iron--Nickel--Tungsten Phase Diagram. F. Winslow Published 1971 Materials Science In support of a study of the properties of liquid-phase-sintered iron-nickel-tungsten alloys, the most probable phase diagram was drawn. The space diagram is shown as a series of isothermal sections between 1,650 and 800° C and a liquidus and solidus projection.

We will limit our discussion of phase diagrams of multi-component systems to binary alloys and will assume pressure to be constant at one atmosphere. Phase diagrams for materials with more than two components are complex and difficult to represent.

Both nickel and manganese, if added in sufficiently high concentration, completely eliminate the bcc α-iron phase and replace it, down to room temperature, with the γ-phase. So nickel and manganese depress the phase transformation from γ to α to lower temperatures (Fig. 1a), i.e. both Ac 1 and Ac 3 are lowered.

[8] Compared to the phase diagram of pure Fe [Hemley and Mao, 2001], it is evident that the stability field of the fcc phase can be extended to higher pressures and lower temperatures with the addition of Ni (Figure 1). However, the effect of Ni on the phase diagram of Fe is not as dramatic as the addition of silicon in Fe [Lin et al., 2002].

The phase relations of an Fe10wt%Ni alloy were investigated in a diamond anvil cell up to 86 GPa and 2382 K. Adding nickel into iron stabilizes the fcc phase to higher pressures and lower temperatures compared to pure iron, and a region of two-phase coexistence between fcc and hcp phases is observed.

For example, in the iron carbon phase diagram, addition of nickel lowers the A3 boundary while the addition of chromium raises it. Eutectic Point Eutectic point is a point where multiple phases meet. For the iron-carbon alloy diagram, the eutectic point is where the lines A1, A3 and ACM meet. The formation of these points is coincidental.
