Influence of Copper Ions on Adherence of Vitreous Coatings to Stainless Steel

Description: Note presenting an investigation of the effect of copper oxide in promoting the adherence of vitreous coatings to AISI type 321 stainless steel. It was found that the copper ions in the coating produced a significant increase in adherence on both pickled and sandblasted surfaces but that the effect of the copper decreased with increased firing temperature and increased firing time for the pickled specimens.

Some Natural Variations in the Relative Abundance of Copper Isotopes

Description: Abstract: "The relative isotopic abundance of copper has been measured in a number of minerals. Suites of samples from Michigan and the Colorado Plateau have been examined to determine if local variations due to isotopic exchange or diffusion could be found. The relative isotopic abundance of copper in specimens from a number of other places was also determined. The variations noted were small but in most cases were felt to be significant because they were larger than the experimental error (0.ā€¦ more

Trace Elements Reconnaissance of the Southern Highway Belt, South-Central Alaska

Description: Abstract: A radiometric reconnaissance of the areas adjacent to the principal highways and secondary roads of south-central Alaska was carried out during the summer of 1947. The investigation included the examination of nine gold-placer workings, five gold lodes, a gypsum mine, and a copper prospect. Nearly all of the lithologic types outcropping in the highway belt were tested. No significant amounts of radioactive material were found.

Low Temperature Mechanical Properties Of Copper and Selected Copper Alloys: A Compilation From the Literature

Description: From Abstract: "In the past 60 years considerable data have been accumulated concerning the mechanical properties of copper and its alloys.It was felt that there was great need to adequately document these results in one publication. Therefore a unique type of compilation is presented. The compilation is divided into four parts. The first section is intended for quick reference use for those who are interested in average values. The second section includes data from most of the investigators whā€¦ more

Dynamics of Radiation Damage: A Report on Recent Results at BNL

Description: Machine calculations have been made of the dynamics of a set of atoms simulating a crystal undergoing radiation damage. Work on copper is reviewed briefly, and its extension to a simple model of ordered Cuā‚ƒAu is described. Investigations of lattice agitation in the wake of a damage event and the extent to which a thermal spike model has validity are discussed. Information on point defects and clusters of point defects in copper is another by-product of the calculations. Recent extensions of theā€¦ more

Dependence of the Elastic Strain Coefficient of Copper on the Pre-Treatment

Description: The effect of various pre-treatments on the elastic strain coefficient (alpha) (defined as the reciprocal of the modulus of elasticity E) (Epsilon) and on the mechanical hysteresis of copper has been investigated. Variables comprising the pre-treatments were pre-straining by stretching in a tensile testing machine and by drawing through a die, aging at room and elevated temperatures and annealing. The variation of the elastic strain coefficient with test stress was also investigated.

Considerations on the Magnet for the 80" Hydrogen Bubble Chamber

Description: For momentum measurements in bubble chambers a magnetic field has to e provided. The following discussion summarizes approximate calculations to determine the necessary amounts of copper and iron for our projected 80" liquid hydrogen bubble chamber magnet. Without any refinements, the accuracy of momentum measurements is proportional to the square of the track length and therefore to the square of the linear dimension of the chamber. If the scale factor for the size of the chamber is Ī», [equatiā€¦ more
