Ni-Pu (Nickel-Plutonium) D.E. Peterson The assessed Pu-Ni phase diagram is based on the work of [51Wen], with review of the data of [55Kon]. The system has six intermetallic compounds (five of which form by peritectic reactions) and two eutectics close to the pure elements. [61Ell] found that (ePu) will dissolve a maximum of 4.3 at.% Ni at 450 C, with the solid solution decomposing eutectoidally into (dPu) and PuNi at 1.5 to 2 at.% Ni and 412 to 415 C [51Wen, 55Kon, 61Ell]. The solubility of Ni in the other Pu allotropes is very small [51Wen, 61Ell]. The maximum Pu solubility in (Ni) was reported by [51Wen] to be about 1.8 at.% Pu at 1210 C. 51Wen: G.W. Wensch and D.D.
