  19. Structural characteristics and elevated temperature mechanical properties of AJ62 Mg alloy

    Structure and mechanical properties of the novel casting AJ62 (Mg6Al2Sr) alloy developed for elevated temperature applications were studied. The AJ62 alloy was compared to commercial casting AZ91 (Mg9Al1Zn) and WE43 (Mg4Y3RE) alloys. The structure was examined by scanning electron microscopy, x-ray diffraction and energy dispersive spectrometry. Mechanical properties were characterized by Viskers hardness measurements in the as-cast state and after a long-term heat treatment at 250 C/150 hours. Compressive mechanical tests were also carried out both at room and elevated temperatures. Compressive creep tests were conducted at a temperature of 250 C and compressive stresses of 60, 100 and 140 MPa. The structure of the AJ62 alloy consisted of primary ?-Mg dendrites and interdendritic nework of the Al{sub 4}Sr and massive Al{sub 3}Mg{sub 13}Sr phases. By increasing the cooling rate during solidification from 10 and 120 K/s the average dendrite arm thickness decreased from 18 to 5 ?m and the total volume fraction of the interdendritic phases from 20% to 30%. Both factors slightly increased hardness and compressive strength. The room temperature compressive strength and hardness of the alloy solidified at 30 K/s were 298 MPa and 50 HV 5, i.e. similar to those of the as-cast WE43 alloy and lower than those of the AZ91 alloy. At 250 C the compressive strength of the AJ62 alloy decreased by 50 MPa, whereas those of the AZ91 and WE43 alloys by 100 and 20 MPa, respectively. The creep rate of the AJ62 alloy was higher than that of the WE43 alloy, but significantly lower in comparison with the AZ91 alloy. Different thermal stabilities of the alloys were discussed and related to structural changes during elevated temperature expositions. - Highlights: Small effect of cooling rate on the compressive strength and hardness of AJ 62 A bit lower compressive strength of AJ 62 compared to AZ91 at room temperature Higher resistance of the AJ 62 alloy to the creep process

  20. Measurement of indirect CP-violating asymmetries in D0?K+K- and D0??+?- decays at CDF

    We report a measurement of the indirect CP-violating asymmetries (A?) between effective lifetimes of anticharm and charm mesons reconstructed in D0?K+K- and D0??+?- decays. We use the full data set of proton-antiproton collisions collected by the Collider Detector at Fermilab experiment and corresponding to 9.7 fb-1 of integrated luminosity. The strong-interaction decay D*+?D0?+ is used to identify the meson at production as D0 or D0. We statistically subtract D0 and D0 mesons originating from b-hadron decays and measure the yield asymmetry between anticharm and charm decays as a function of decay time. We measure A?(K+K-)=(-0.190.15(stat)0.04(syst))%and A?(?+?-)=(-0.010.18(stat)0.03(syst))%. The results are consistentmorewith the hypothesis of CP symmetry and their combination yields A?=(-0.120.12)%.less

  2. Carcinogenic effects in A/J mice of particulate of a coal-tar paint used in potable water systems

    Coal-tar paints are among the products used as inside coatings for water pipes and storage tanks to retard corrosion in potable water-supply systems. Four different formulations of these paints were tested in earlier work by this laboratory in the Ames mutagenesis and the mouse skin carcinogenesis bioassays(6). The paint most active in these assays was then tested in a particulate form in the lung adenoma assay with A/J mice. The paint was applied to clean glass plates, cured, collected and homogenized in 2% Emulphor. Doses of this coal-tar suspension were administered by gavage at 1.0, 10.0, and 55.0 mg in 0.2 ml per mouse 3 x weekly for 8 weeks. The total doses of coal-tar paint were 24, 240, and 1320 mg/mouse. Benzo(a)pyrene, administered in a parallel schedule to a total dose of 6 mg/mouse, served as positive control. A negative control group received an equivalent volume of 2% Emulphor. Animals were sacrificed at 9 months of age (8 months after first dose) and lung adenomas counted. A dose-related response, in the average number of lung tumors per mouse, was observed with the coal-tar particulate. There were also squamous-cell tumors of the forestomach in 42% of the mice receiving 55.0 mg coal tar paint per application.

  7. Resonances in Coupled ?K??K Scattering from Quantum Chromodynamics

    DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

    Dudek, Jozef J.; Edwards, Robert G.; Thomas, Christopher E.; Wilson, David J.

    2014-10-01

    Using first-principles calculation within Quantum Chromodynamics, we are able to reproduce the pattern of experimental strange resonances which appear as complex singularities within coupled ?K, ?K scattering amplitudes. We make use of numerical computation within the lattice discretized approach to QCD, extracting the energy dependence of scattering amplitudes through their relation- ship to the discrete spectrum of the theory in a finite-volume, which we map out in unprecedented detail.
