    The combination of chemical composition and microstructure of cast alloy has been found to be critical to the performance of NdFeB sintered magnets. Maximizing the amount of Nd2Fe14B phase (or minimizing the amount of secondary phase) by reducing the Nd content more closely to the stoichiometric composition appears to be essential for obtaining high BHmax magnets. However, α-Fe precipitation has been found to increase with decreasing Nd content and severely hinders the development of high BHmax magnets. A two-step method, incorporating ingot casting and isothermal annealing, has been developed to minimize the amount of precipitated α-Fe in low Nd content alloys. This method provides a drastic improvement in the Br and BHmax of sintered magnets obtained. By decreasing the Nd content to 13 at. % in the cast alloy, incorporating better particle control during fine milling, and controlling grain growth during sintering; magnets with a Br of more than 14.5 kG and a BHmax of 50 MGOe have been consistently obtained. Furthermore, because of the reduction in the amount of Nd-rich grain boundary phase, a significant improvement in the corrosion resistance of magnets was also observed. © 1996 American Institute of Physics.

    Notes:
    Magnets with a nominal composition of Nd14.5Fe79.5B6 have been prepared by the conventional powder metallurgy technique. Precursor alloy powders with average particle sizes of 2.5, 3.0, 3.5, and 4.2 μm were included in this study. Average particle size and oxygen content were effectively manipulated to control the average grain size in the sintered magnets. Typically, for NdFeB sintered magnets, the corrosion resistance of these magnets was improved with increasing oxygen content. The corrosion resistance of magnets varied significantly with the average particle size of precursor alloy powders. For a fixed oxygen content, magnets made from powders of larger sizes exhibited a higher weight loss (a poor corrosion resistance) when compared to those made from smaller alloy powders. However, the Hci of magnets made from 2.5, 3.0, and 3.5 μm precursor alloy powders was found to decrease drastically with increasing oxygen content while magnets made from the 4.2 μm powder was found to remain relatively constant with increasing oxygen content. To optimize magnetic performance, one needs to compromise the corrosion resistance and the Hci obtained by balancing the average particle size of the precursor alloy powder for magnet fabrication, as well as the oxygen content and the average grain size in the finished magnet. © 1996 American Institute of Physics.

    The microstructure of conventionally cast Sm(CobalFe0.28CuvZr0.022)8.0 alloys, where v=0.043–0.092, were examined by optical microscopy and scanning electron microscope with energy dispersed analytical x ray in the as-cast state. In addition to the regular 2:17 matrix phase, the Sm-rich grain boundary phase and the needle-like Zr-rich phases are present in most commercial Sm(Co,Fe,Cu,Zr)z alloys. A grayish Sm- and Cu-rich grain boundary phase was found in alloys with v≥0.07. Attention was focused on the impact of increasing Cu content to the microstructure and process parameters required to produce coercive powder for bonded magnets. An increase of the Cu content from the v value from 0.043 to 0.092 shifts the liquid+2:17→TbCu7-type transformation temperature from slightly above 1180 to approximately 1140 °C. The Hci of optimally prepared magnet was found to increase significantly while the Br remained relative constant when the Cu content is increased. When the Cu content was increased to beyond v=0.07, a slight decrease in the BHmax was noticed. A magnetizing field of 15 kOe and more than 50 kOe were determined to be necessary to charge magnets with a Hci of 12 and 25 kOe, respectively, to about 90% of their full potential. For a composition of Sm(CobalFeuCu0.07Zr0.022)8.0, a slight increase in Fe concentration from u=0.22 to 0.28 was found to increase the Br of an optimally prepared magnet from 8.07 to 8.28 kG and decrease the Hci from 11.8 to 9.7 kOe. A BHmax of 15 MGOe was obtained on a bonded magnet with a composition of Sm(CobalFe0.28Cu0.07Zr0.022)8.0 when the data are normalized to a specific density of 7.0 g/cm3. © 1996 American Institute of Physics.

    Notes:
    Temperature-dependent magnetic properties of nine NdFeB sintered magnets with various Co-Nb, Co-V, or Co-Mo additions have been measured up to 175 °C using both closed-loop and open-circuit methods. The irreversible loss of induction, reversible temperature coefficient of induction (α), and temperature coefficient of intrinsic coercivity β have been related to the Tc, the Br, and the Hci at 25 and 175 °C. The irreversible loss of induction is strongly affected by the Hci at 25 °C and the α has been found to be strongly dependent upon the Tc. Intrinsic coercivity of more than 25 and 7.5 kOe at 25 and 175 °C, respectively, are essential to bring the β to better than −0.5%/ °C. A magnet with a composition of Nd12Dy3Fe70Co5Nb2B8 has been found to exhibit an outstanding thermal stability: a Br of 8.5 kG (comparable to that of SmCo5 sintered magnet) and a Hci of 12.9 kOe when measured at 175 °C. An α of −0.10%/ °C and a β of −0.4%/ °C have been obtained.

    Summary To investigate changes in surface proteins of uterine cells in relation to the time of implantation, epithelial and stromal cells were isolated from rabbit endometrium and maintained in primary culture for 3 days. Surface-iodination of intact cells was carried out before and after culture, using immobilized Iodogen catalyst. The labeled proteins were analyzed by polyacrylamide gel electrophoresis, followed by autoradiography; peak areas were quantitated by scanning densitometry. Different gestational ages showed no marked qualitative differences in the surface-iodination patterns either of epithelial or stromal cells before or after culture. Quantitative differences between the surface-iodination pattern of epithelial cells from days 4 to 6.5 of pregnancy were revealed by canonical variate analysis of labeled peak areas. Values for individual rabbits clustered according to gestational age, with significant (p〈0.05) separation of the clusters, although the discrimination was less pronounced for cultured than for freshly isolated cells. Changes involving increases in labeling of a protein of 38 000 Mr in fresh cells, and decreases in a protein of 42 000 Mr in cultured cells, were evident between day 4 and day 6.5. Thus changes in the surface-labeling pattern of uterine epithelial cells in relation to the time of receptivity for ovoimplantation can be distinguished. The functional significance of these changes remains to be elucidated.

    Notes:
    Summary We have previously used surface iodination to discriminate between the protein patterns of epithelial cell surfaces in uteri of rabbits receptive (Day 6.5) or nonreceptive (Day 4) to nidation (Ricketts et al. 1984). In this paper, we describe application of the same technique to the trophoblastic surface of rabbit blastocysts collected on the same days of pregnancy. Analysis of labelled proteins by polyacrylamide-gel electrophoresis under denaturing conditions did not reveal qualitative differences between the two days of pregnancy. Scanning densitometry was used to quantitate the area under each protein peak on an autoradiogram; these areas were used as variables in statistical analysis of the protein pattern of individual animals. Quantitative differences between the protein patterns of the two surfaces were detected by canonical variate analysis of the pattern of relative areas of labelled protein peaks. In proteins separated on 7.5% gels, this statistical analysis correctly assigned blastocysts from 8 out of 10 animals to one of two groups according to day of pregnancy. The discrimination was not statistically significant, however, in protein patterns on 12.5% gels, used to give better separation in the lower range of molecular weights. The same analysis in the uterus unequivocally separated the surface iodination patterns from these same days of pregnancy. Thus the changes detected by surface iodination appear to be less pronounced on the trophectoderm than on the uterine epithelium in relation to the time of ovoimplantation.

    Notes:
    Summary In this paper the problem of automatic calibration of histograms by cross-validation is considered, assuming the true underlying density is continuous with continuous first derivative. The histogram is one of the simpliest semiparametric estimators used by economists, but it is surprisingly difficult to construct histograms with small estimation errors. Cross-validation algorithms attempt to automatically determine histogram bin widths that are nearly optimal with respect to mean integrated squared error. Alternative philosophies and approaches of cross-validation for histograms are presented. It is shown that the classical Sturges' rule performs poorly and that cross-validation is a relatively difficult task. Understanding the performance of cross-validation algorithms in this simple setting should prove valuable when cross-validating other more complex semiparametric procedures.
