Au-Pu

Au-Pu (Gold-Plutonium) H. Okamoto, T.B. Massalski, and D.E. Peterson The Au-Pu system is characterized by the presence of eight intermetallic compounds, four eutectics, four peritectics, and a peritectoid. The assessed phase diagram is primarily a composite of the work of [65Hoc] and [65Kut]. The Au melting point is taken from [Melt], and the transformation temperatures for the Pu allotropes are from [84War]. [65Hoc] found no solid solubility of Au in (aPu), but observed that Au dissolves in (ePu) sufficiently to raise the melting point to 652 C. This action leads to a peritectic reaction L + AuPu = (ePu) at about 99 at.% Pu. 65Hoc: B. Hocheid, A. Tanon, S. Bedere, J. Despres, S. Hay, and F. Miard, Plutonium 1965, Proc. 3rd Int. Conf.
