The Mechanical Properties of Beta-Quenched Uranium at Elevated Temperatures

Description: The creep strength and tensile properties-were determined in vacuum for beta-quenched, derby uranium. The stresses to produce a secondary creep rate of- 0.0001 per cent per hr at 100, 250, 400, and 500 deg C were 48,000, sile strengths were 114,500, 35,100, 11,100, and 8,500 psi at temperatares of 28, 300, 500, and 700 deg C, respectively. The creep and tensile strengths decrease quite rapidly with increasing temperature in the temperatare range 250 to 400 deg C. (auth)

The Properties and Heat Treatment of Zirconium-Uranium Alloys

Description: From Abstract: "The heat treatment and mechanical properties of four zirconium alloys...were investigated. Tensile, hardness, Jominy end-quench, and metallographic data constitute the basis for much of the report. Other data reported include the results of high-temperature creep, tensile, hardness, cold rolling, thermal-cycling, and dynamic-modulus tests." A connection is made between the behavior of these four alloys and more alloys in the zirconium-uranium system.

Interaction of Bearing and Tensile Loads on Creep Properties of Joints

Description: The interaction of bearing and tensile loads on the creep behavior of joints was studied. A specimen was designed for this study which possessed some of the general features of pin and rivet joint connections and an apparatus was constructed to apply both bearing and tensile loads to the joint model. Deformation measurements were made by use of a photogrid printed on the joint model.

Creep of Aluminum-Copper Alloys During Age Hardening

Description: Note presenting a study of the interrelation of aging during creep and of creep during aging in polycrystalline aluminum alloys containing 1 to 4 percent copper. Experimental procedures included interrupted creep tests, tensile tests of crept specimens, quantitative metallographic determination of the percent precipitation during creep, hardness measurements on unstressed and stressed aged alloys, X-ray studies of deformation in the crystalline lattice, and microscopic examination of the surfac… more

Study of Hydrogen Embrittlement of Iron by Internal-Friction Methods

Description: Note presenting the effects of electrolytic charging on the properties of relatively pure iron and tempered 4340 steel investigated metallographically and by observing internal-friction behavior from -196 to 430 degrees Celsius. Electrolytic charging caused severe structural damage to both iron and steel, consisting of blisters and internal cracks.

Effect of Precipitate Particles on Creep of Aluminum-Copper Alloys During Age Hardening

Description: Note presenting an investigation of spherical or platelike precipitates prepared in aluminum alloys with 1 to 4 weight percent copper. The effects of controlled sizes and distributions of particles were determined by creep, tensile, and hardness measurements by quantitative metallographic evaluation of the particle characteristics, and by X-ray and electron-microscope examinations.

Creep Deformation Patterns of Joints Under Bearing and Tensile Loads

Description: Note presenting an investigation to study the interaction of bearing and tensile loads on the creep behavior of joints. A simplified model was employed which contained many of the features found in riveted connections. Results regarding creep-rupture tests, plate subjected to tension, plate subjected to bearing loads, plate subjected to tensile and bearing loads, and index of joint behavior are provided.

Investigation of Plastic Behavior of Binary Aluminum Alloys by Internal-Friction Methods

Description: Note presenting an investigation indicated that nominal additions of 0.1, 1.0, and 5.0 weight percent copper and magnesium to aluminum have significant effects on damping behavior. An internal-friction peak at abotu 125 degrees Celsius was observed in aluminum containing 1 percent copper and is believed to result from the interaction of dislocations and impurity particles. The internal friction during plastic deformation was sensitive to strain rate, amount of strain, alloy content, heat treatm… more
