Abnormal grain growth in nickel-base heat-resistant alloys

Description: From Introduction: "The data included in this report for Nimonic 80A alloy, for instance, represent experiments carried out to help clarify a production problem of grain-size control in an alloy which has been extensively used. The general procedure of the investigation was to carry out controlled laboratory experiments on samples of bar stock to find conditions of heating and hot-working which resulted in abnormal grain growth."

[Frozen Milk Bottles]

Description: Photograph of two frozen milk bottles in Detroit. They appear to be seated on someone's doorstep. One of the bottles has cracked, leaking milk onto the ground. This photograph is part of Joe Clark's "Detroit" series. Narrative by Junebug Clark: This photo of two frozen milk bottles on our front porch at 12135 Klinger Ave in Hamtramck, Mich. was a common scene in the Winter months. Our Twin Pines milk man would deliver early in the morning and by the time we could get to them.... All we could do was scrape the cream that had risen to the top and pushed the stopper out. This photo was used by Pure-Pak in an effort to promote the use of cardboard milk cartons. A hard sell because everyone believed that glass was best. Photo by: Joe Clark, HBSS.

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 (0.1 percent in the ratio). A total spread of +3 to -8 parts per mil compared to the standard was found in the specimens tested."
