METALLOGRAPHIC AND X-RAY OBSERVATIONS OF Pu-C ALLOYS
Technical Report
·
OSTI ID:4639557
Metallographic, x-ray diffraction, and incipient-melting techniques were used to investigate the Pu-C phase diagram below 50 at.% C and for temperatures between 500 and 1500 deg C. The variation of lattice parameter with composition for Pu--C alloys is presented and used to define portions of the low-carbon boundary of the PuC phase field. Unique microstructural characteristics are detailed for the epsilon Pu + PuC in equilibrium Pu/sub 3/C/sub 2/ peritectoid reaction, namely, the preference of the Pu/sub 3/C/sub 2/ phase to grow as platelets rather than as an interfacial envelope surrounding the PuC reactants. Some aspects of coring in cast alloys containing the monocarbide phase are discussed. (auth)
