“…[29,30] For example, our previous study on Ni 3 Si showed that Ta (0.148 nm) substituted for Ni (0.125 nm) had much larger solid solution capability than Ta substituted for Si (0.134 nm). [31] Thus, substantial solid solution hardening superimposed on precipitation hardening occurred in the 3Mo(Ni)3Nb and 3W(Ni)3Nb alloys, as shown in Figures 7 and 15. To determine the optimum hardness of the present two-phase intermetallic alloy containing Mo or W, it is important to evaluate the relative contribution of the phase separation and (Mo-or W-rich phase) precipitation to the overall hardening.…”

Fine precipitation was observed in the channel region of the Ni-based, two-phase Ni 3 Al and Ni 3 V intermetallic alloys containing Mo and W, which are soluble in the A1 phase at high temperatures but less soluble in the two intermetallic phases at low temperatures. The fine precipitates were identified as Mo-or W-rich phases (Mo solid solution with a body-centered-cubic (bcc) structure or Ni 4 W with a tetragonal structure) accompanied by a rigid orientation relationship and a habit plane with the constituent phases in the channel region. Fine precipitation was induced when added elements were substituted for Ni, thus, stabilizing the two intermetallic phases; however, it was not induced when the two intermetallic phases were destabilized by the addition of elements to substitute for Al and V. Fine precipitation was induced to a greater extent when Nb was concomitantly added to the alloys with Mo or W and when the two intermetallic phases were stabilized. Annealing at temperatures below the eutectoid temperature was necessary to induce fine precipitation in the alloys containing W. Accordingly, age hardening by annealing did not occur in the alloys containing Mo but did occur in the alloys containing W, whose behavior was correlated with the difference in the diffusivity of the Mo and W elements in the two-phase eutectoid microstructures (phases).
