ADVANCED PRESSURE VESSEL MATERIALS.

Description: Data on 5Cr - 3Mo - 12Ni alloy, PH13 - 8Mo and Iconel 718 for pressure vessel application are given. The 5Cr - 3Mo - 12Ni posseses characteristics suited to uniform aging of heavy sections. Tensile and toughness properties are good, and structural stability up to 315 deg C is adequate. Weldability with 12Ni - 3Cr - 3Mo filler material is good but 12Ni - 5Cr - 3Mo filler is more efficient. Aging characteristics of PH13 - 8Mo may not be suited to uniform aging of heavy sections. Excellent tensile… more

D.C. Arc Excitation of Impurities in Plutonium Dioxide Using Carrier Distillation Techniques.

Description: The effect of various carrier compounds and methods of preparation of plutonium dioxide upon the spectral emission of trace metallic impurities have been studied. By using an emission spectrometer, equipped with a chart readout, excitation rates have been established for elements analyzed by the carrier distillation technique. This study has shown that the use of 8.3% AgCl-LiF (11:1) in plutonium dioxide gives the most sensitive and reproducable excitation for the majority of impurity elements.… more
