Microstructural analysis of fracture toughness variation in 2XXX-series aluminum alloy composites reinforced with SiC whiskers

The effects of local microstructure on fracture properties in powder-metallurgy (P/M)-processed 2124/SiC/15w and 2009/SiC/15w composites are analyzed in this study. Ductility and fracture toughness of the 2009/SiC/15w, in which dispersoid-forming elements such as manganese and iron were nearly absent, were greater than in the 2124/SiC/15w, while its tensile and yield strengths were somewhat less. Microstructural examination and fracture parameter analysis revealed that the improved fracture toughness of the 2009/SiC/15w compared to the 2124/SiC/15w was due to the increase in the critical microstructural distance,l* when manganese-containing particles are absent. 2009/SiC/15w was also heat-treated in T4P and overaged (OA) conditions. The OA 2009 composite showed lower fracture toughness than the 2009-T4P composite and the critical fracture strain of the OA condition was much lower, too. Detailed fractographic analyses indicated that interface precipitates facilitate premature SiC whisker failure in the OA condition.

轻压下技术在高碳钢方坯连铸中的应用

台湾中钢、韩国浦项等5家钢厂在高碳钢方坯连铸中采用轻压技术之后，铸坯中碳和其它元素的中心偏析程度明显降低，缩孔和中心疏松缺陷也大大减少。从这些厂家的应用效果还可以看出，普通的轻压下技术，即机械轻压下技术用于小方坯连铸似乎存在一定的局限性，而热轻压下技术则为小方坯连铸提供了一种新的选择。

Effect of crossing a line selected for increased shank width with two commercial sire lines on performance and walking ability of turkeys

Published research indicated that a line (FL) of turkeys selected for increased shank width and exhibiting good walking ability (WA) and improved leg structure was useful in improving WA of a cross with an unimproved commercial sire line while remaining competitive in BW and body conformation. The purpose of the present study was to determine whether the FL line was useful in improving WA of two improved commercial primary-breeding sire lines and to study the inheritance of BW traits in the pure lines and reciprocal crosses of the pure lines. Samples of a primary breeding sire line from each of two major commercial turkey breeders were obtained as unpedigreed eggs and designated as Lines A and B. Lines A and B were reciprocally crossed with the FL line that had been selected for increased shank width for 16 generations. Pure lines and reciprocal crosses were produced by artificially mating 10 males to 15 females using pooled semen. The same semen pools were used to produce both the pure lines and the crosses. Traits measured included BW at 8, 16, and 20 wk of age, and length, width, and depth of the shank, width of the breast, and WA at 16 wk of age. The A and B lines were larger and had wider breasts and narrower and shorter shanks than the FL line. Line B was larger than Line A. Shank measurements and WA score did not differ between Lines A and B in either sex. Breasts of Line B females were wider than those of Line A females, but there was no sire line difference in breast width of males. Heterosis in BW was greater in Line A crosses (average of 4.6% with a range of 2.5 to 7.2% for BW at different ages) than in Line B crosses (average of 2.2% with a range of 0.1 to 5.3%). Heterosis in WA score was negative (crosses had better WA than pure lines) for males [14% for the Line A and FL crosses (P < or = 0.001) and 4% for the Line B and FL crosses (P < or = 0.05)], but was positive and nonsignificant for females of the above crosses (average of 2.6 %). With one exception, heterosis was not an important source of variation for shank width or shank depth and there was a low level of heterosis for shank length. No heterosis was observed for breast width. Reciprocal effects were an important source of variation in BW and shank measurements for females but not for males in both sets of crosses. The results of the present study indicated that use of the FL line to improve WA of improved primary-breeding commercial sire lines was not a feasible alternative. The slight improvement noted in WA of the male crosses was offset by the reduction in BW and breast width of the crosses relative to the pure commercial sire lines.

Job attitudes in mangement: III. Perceived deficiencies in need fulfillment asa function of line versus staff type of job.

This study focused on differences in perceptions of the degree of fulfillment and importance of several types of psychological needs associated with line versus staff types of management jobs. Data were provided from a questionnaire, and the nation-wide sample of respondents included 1802 managers from a wide variety of types of companies. Results showed: (a) Line managers perceived greater need fulfillment than staff managers, with the largest line-staff differences occurring in the Esteem and Self-Actualization need areas. (b) Line and staff managers did not differ on the importance they attached to each type of need, with the exception of Autonomy needs which staff managers considered more important. (c) Effects of the line-staff variable were smaller than effects of the variable of vertical level of position within the management hierarchy.
