THE REACTION OF HYDROGEN WITH ZIRCONIUM-1 AND -25 w/o URANIUM ALLOYS
Hydrogen-absorption isotherms were measured over the range 535 to 835 C for zirconium--1 wt.% and--25 wt.% uranium alloys. X-ray-diffraction studies were made over approximately the same temperature range for the zirconium--1, -- 25, and --50 wt.% uranium alloys. In general, the alloys resenable the zirconium- hydrogen system, modified by the presence of uranium. With 1 wt.% uranium, the phase boundaries of the zirconium--hydrogen system are shifted to slightly lower hy-drogen contents. With 25 wt.% uranium, the first - two-phase-' region shifts to a hydrogen content 20 wt.% greater than in the zirconium--hydrogen system, while the second cctwo-phase'' region is unchanged. The eutectoid temperature is increased from 547 to 601 C. Heats of solution of hydrogen in the alloys were found to range from --25.9 to --47.9 kcal per mole for the 1 wt.% alloy, and from --30.7 to --50.6 kcal per mole for the 25 in.% alloy-. The x-ray-diffraction data support the interpretation that, as hydrogen is absorbed, the alloys break down to form uranium and zirconium, and the latter absorbs the hydrogen. The entire ternary isotherms could not be deduced from the data. However, three aspects appear certains (1) the extent of the phase fields along the zirconium-- hydrogen …

The Heat Treatment, Transformation Reactions, and Mechanical Properties of Some High-Strength Zirconium-Base Alloys
Zirconium alpha-beta alloys were found to respond to solution and aging heat treatmeats very similarly to titanium alpha-beta alloys. A zirconium-5 wt.% molybderum-2 wt.%fl tin alloy was heat treated to a L68,500-psi tensile strength and a 153,500-psi yield strength, with 11.5% elongation in 1 in. In addition, a zirconium-5 wt.% niobinm-2 wt.% tin alloy was heat treated to a 190,500-psi tensile and a 178,000-psi yield strength, with 2% elongation. The transformations that occur upon aging these alloys may be represented as follows: beta deg C was con- omega + beta /sub r/ deg C was con- alpha + beta / sub u/and alpha deg C was con- alpha + beta /sub r/. Preliminary elevated-temperature propenties were very good. The zirconium-5 wt.%fl molybderum-2 wt.%fl tin alloy solution treated at 1525 F and aged 8 hr at 1000 F was evaluated for tensile strength and 100-hr rupture life at 840 F. The tensile strengh, yield strength, and elongation were 111,000 psi, 84,500 psi, and l2%fl, respectively. The 100-hr rupture strength was about 95,000 psi. (auth)

Lead-Alpha Age Determinations of Granitic Rocks from Alaska
Abstract: "Lead-alpha activity age determinations were made on zircon from seven granitic rocks of central and southeastern Alaska. The results of the age determinations indicate two periods of igneous intrusion, one about 95 million years ago, during the Cretaceous period, and another about 53 million years ago, during the early part of the Tertiary. The individual ages determined on zircon from 2 rocks from southeastern Alaska and 1 from east-central Alaska gave results of 90, 100, and 96 million years; those determined on 4 rocks from central Alaska gave results of 47, 56, 58, and 51 million years."

A Study of the Mechanisms of Heat Treatment of Zirconium-Base Alloys : Status Report, July 1, 1955 - February 29, 1956
The kinetics of transformation of zirconium binary alloys is being pursued. Mechanical property variation as a function of transformation if also being investigated. Zirconium-tin and zirconium-titanium alloys transform very rapidly when quenched from the beta field. These alloys have, generally speaking, been demonstrated to be not amenable to heat treatment in the normal sense of the word. Eutectoid alloys, principally zirconium-molybdenum alloys, have shown a definite response to heat treatment in terms of mechanical property variation. An embrittling agent, probably "omega" phase, is suspect at this time for the brittleness observed in certain molybdenum alloys and the very high hardness levels reached in other alloys such as zirconium-niobium and zirconium-thorium. Work to establish the existence of omega phase is in progress and, it is hoped, suggestions for avoiding the brittle condition associated with it will be forthcoming.

Special Zirconium Alloys. Report No. 18 (Summary) for January 1, 1956- October 31, 1957
Tensile properties amd impact strengths were determined for iodide Zr, sponge Zr, and alloys based on both grades of metal, containing nominally 1.5% M. Sheet specimens, welded and unwelded, were tested. Tensile properties were established at room temperature and 300 deg C. Impact strength values were measured at --100 deg , R.T., 100 deg , 200 deg , and 300 deg C. These (alpha) materials generally exhibited a lack of heat treatability, litile or no deterioration of properties due to welding, and essentially no indication of impact transition temperature. Tensile strength and impact behavior were established for alloys based on iodide zirconium containing 15% Nb, 15% Nb + 2% Pd, 15% Nb + 2% Pt, 15% Nb + 1% Fe, and a binary sponge zirconium + 15% Hb alloy. High strength levels could be established by proper heat treatment. The presence of Pd, Ft, or Fe seemed to delay the formation of the embrittiing agent as determined by hardness and resistivity vs time of anneal curves for these alloys. uth)

An apparent phase transformation was detected in high- purity Ga deformed at 4.2 deg K. The specific heat of the group IV-A metals and alloys of Zr-In and Zr-Sn were measured from 1.2 to 4.5 deg K. In the Zr-rich portion of the Zr-Ga phase diagram, the alpha / beta phase boundaries of Zr are depressed by additions of Ga and the beta phase decomposes by a eutectoid reaction. The Cd pressures of alpha - and beta - Zr alloys containing 1 to 11% Cd were measured between 1090 and 1325 deg K. Crystal structures of several unreported transition-metal fluorides, rare-earth hydrides and nitrides were determined. Progress in the study of phase transitions in beta -quenched Zr-Nb alloys aged below the eutectoid temperature is reported. A high-temperature investigation of the order-disorder phase transition of a Cu31 at.% Au alloy has revealed an intermediate periodic antiphase condition. A previously described x- raydiffraction technique for the measurement of the thickness and strain of …

Uranium Alloy Newsletter
Argonne National Lab. Annealing experiments of highpurity C --U alloys in the gamma region in an Ar atmosphere show that the metal is subject to decarbinization. Fourteen binary U--Pd alloys were prepared and examined. Pd solubility in gamma U is less than 1 wt.% at 890 deg C. Seventeen binary alloys of U-Ru were prepared and examined in the as-cast condition. The corrosion resistance after irradiation of U--Si alloys was tested. Homogeneous U- -Ta alloys have not been obtained. Th-rich U alloys were found to be more stable under irradiation than the best U alloys. The effect of heat treatment on microstructure is being studied as part of the effort to understand the effect of alloying on corrosion resistance in Ti--U alloys. Crystal and corrosion studies on U--Zr alloys are reported. Armour Research Foundation. Small ternary additions were found to greatly affect the transformation characteristics of U-- Nb alloys, and a hardness change was noted for this alloy. Preliminary data for U--Nb--Zr alloy demonstrated a relationship between the strained matrix and the physical properties of the alloy. Battelle Memorial Institute. Phase relationships between the intermediate delta phases of the U--Mo and U--Ti systems were conducted. U--Zr, U--Mo, and U--Nb alloys …
