As-cast Mar-M200 consists of ∼60 vol. % coherent precipitate of γ′ (Ni 3Al solid solution) in a matrix of γ (nickel solid solution). In the solutionized and quenched condition, Fig. 1 (a), the γ′ particles are ∼50-100Å Dia., and exhibit long range order; see relatively weak superlattice reflections (S) compared with main reflections (M) in the inset of Fig. 1 (a). Note that the equilibrium partitioning of the solid solution elements between the γ and γ′ phases may not have been realized owing to the fast quench. Quenched-in thermal vacancies should facilitate exchanges in nearest neighbor atoms to produce ordered regions of γ′. Aging at 800°F gives γ′ particles ∼750¥, Fig. 1 (b), which are recognizably cuboidal in shape. Aging at 1550°F yields γ′ particles ∼1500¥, Fig. 1 (c), together with new precipitates of M23Cg6 carbides (arrows) and many stacking faults.

Cuboidal Precipitate

The microstrueture of a commercial nickel-base alloy normally consists of a coherent, cuboidal precipitate of γ’ (alloyed Ni3Al) in a matrix of γ (Ni solid solution). Recently, Ham et al., working with the ternary alloy 78Ni-l8Al-4Ti (a/o), have shown that by appropriate heat treatment a completely novel microstrueture can be developed, in which the matrix is γ’ and the precipitate is platelet γ. The present study represents an extension of this work, and reports some new findings on precipitation of γ in γ’ in alloys similar in composition to the Ni-Al-Ti alloy but with Ta replacing Ti.The alloys used were solutionized in the range 2200-2400°F and aged at l600°F for 24hrs (giving ∼ 10 vol. percent of γ in γ’). According to our most recent findings, unlike the binary system, the solubility of γ’ for γ reaches a maximum at ∼ 2200°F in these alloys.

The formation of stacking faults upon aging a solution treated and quenched nickel-base alloy has been reported previously. More recent work has revealed a similar behavior in several γ’ precipitation hardened nickel-base alloys aged in the temperature range l400°-1650°F. The faults intersect both γ (nickel solid solution) and γ’ (Ni3Al solid solution) phases, and are of extrinsic type. Fault formation is attributed to a chemical segregation effect involving the climb of Frank partials, similar to that reported for austenitic steels.Fig. 1 shows extrinsic faults associated with a slip band in Udimet 700 lightly deformed at 70°F prior to aging. For the specified [011] normal to the foil, the slip trace is (11), and the faults lie in (111) and (11). Using the g · b = 0 or ± 1/3 (s = 0) criterion for dislocation invisibility, Figs, 1 (a-c) show that the outer partial for a (111) fault must be 1/6 [11] Shockley, or 1/3 [111] Frank.
