Preparation of Samples of 42 Weight Percent U-Al Alloy for Pile Irradiation Tests

Description: Abstract: Processes are described for preparing small samples of 42 wt. % U-Al alloy (uranium enriched with U235) for pile irradiation studies. In the course of this work it was found that the size of the massive Al-U grains remains substantially unaltered during hot rolling.

Creep Strength of Uranium Alloys at 1500 and 1800 F

Description: Abstract:"The creep resistance of various uranium binary alloys was investigated at 1500 and 1800 F in vacuum. Tests were made on alloys of uranium with beryllium, columbium, molybdenum, tantalum, titanium, and zirconium and on molybdenum-UO2 composites. Of the alloys examined, those of the uranium-molybdenum system exhibited the best creep resistance. At 1500 F, creep rates of about 0.005%/hr were produced in uranium-molybdenum alloys by a stress of 2500 psi and, at 1800 F, similar creep rates were obtained in composites of 90 wt % molybdenum-10 wt % UO2 by a stress of 12,000 psi."

The Uranium-Cobalt System

Description: Abstract: "A phase diagram for the uranium-cobalt system has been constructed, based on thermal, microscopic, X-ray and chemical data. The results indicate the existence of three compounds and two eutectics, one of which shows a lowering of the melting point of uranium by approximately 400 C."

The Uranium-Titanium Alloy System

Description: Abstract: "A uranium-titanium constitution diagram is presented. There is complete solid solubility between titanium and gamma uranium above about 2100 F. Only one compound exists in the system. It has a hexagonal structure based on U2Ti. It has a fairly wide range of stability, particularly on the titanium side. Beta-titanium solid solution decomposes eutectoidally into alpha titanium and compound at 1150 F. Eutectoid composition is about 72 atomic per cent titanium. Gamma-uranium solid solution decomposes eutectoidally at 1325 F into beta uranium and compound. Eutectoid composition is about 6 atomic per cent titanium. Beta uranium and compound react peritectoidally at 1233 F to give alpha uranium. Solubility of titanium in alpha and beta uranium is low as is the solubility or uranium in alpha titanium."

The Vanadium-Uranium Constitutional Diagram

Description: Abstract: "Vanadium-uranium equilibrium studies were made on alloys prepared from high-purity vanadium and good biscuit uranium. No intermetallic phases occur in the system. Additions of vanadium lover the uranium melting point and transformations producing a eutectic at 1240 +/- 5 C and eutectoid reactions at 727 +/- 5 and 652 +/- 5 C. The maximum solubility of uranium in vanadium is about 4 atomic per cent (15 weight per cent)."

Grain Refinement of Uranium by Alloying

Description: Binary alloys of uranium with 38 elements in the range 0.01 to 1.0 at.% were made. Three alloys having nominal compositions of 0.01, 0.1, and 1.0 at.% were made with most of the elements, and in addition, 12 ternary and quaternary alloys were made. The alloys were cast, rolled to 7/8-inch-diameter bars, heat treated, and examined for grain size.

Transformation Characteristics of Low Ternary Alloys of Uranium

Description: Abstract: "A series of ternary additions of niobium, platinum, and molybdenum, of the order of 1.0 w/o and less, have been made to binary uranium - 0.5 w/o titanium, an alloy of some promise in the 7-heat-treated, water-quenched condition. Jominy bars of nine such alloys were tested, microstructurally examined, and hardness profiles obtained over their length. This paper deals with observations made for correlation of transformation behavior, microstructure, and hardness profiles over the spectrum of cooling rates experienced, directed toward the end of determining the effect of ternary additions in improving the properties of uranium."

Jacketing of Uranium for High-Temperture Service

Description: From introduction: "The work covered in this report is a portion of the experimental research undertaken for the design of a uranium-containing metallic fuel rod for operation in air at 1090 C...This report deals with that phase which involved the testing and evaluation of various metals as barrier costs between uranium alloys, and low-carbon steel. The work is of a preliminary nature and is concerned more with a comparison of the various barrier metals than with the acquisition of numerical data, e.g., diffusion coefficients."

Summary Report: AEC Reference Fuel-Processing Plant

Description: From introduction: The primary purpose of this report is to record the bases chosen in setting the Commission's policy on processing charges to assure that individual charges are on a consistent basis in conformance with the policy. Secondly, it may aid reactor operators in estimating the AEC processing charges for a variety of fuels and reactor conditions. It may also be of interest to potential chemical processors by showing the approach followed in developing these charges.
