University Micrdfilms International 300 N INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1. The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)” . If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy has been filmed. University Micrdfilms International 300 N.

Burnham Professor Mansel Blackford Dedicated to Mary Jean, Amy, and the "Colonel" ii SPECIAL ACKNOWLEDGMENT I wish to thank the Wheeling-Pittsburgh Steel Corporation and especially Mr. Roger McLean, Mr. Harry Sykes, and Mr. Joseph Wurtenberg, who located and made available records of the firms in and around Wheeling, provided technical information on nailmaking, and generously allowed me to tour one of the last operating cut nail mills. Without the cooperation of these gentlemen and the Wheeling-Pittsburgh Steel Corporation, this study would not have been possible. PREFACE My interest was attracted to the history of nail manufacturing in 1975 while directing research for a museum on the Ohio Valley ceramic industry. As a part of the background research, the staff of the Ohio Historical Society identified several major industries— ceramics, tex­ tiles, glass, iron, and coal mining— that either existed or had existed in the area between the Ohio-Pennsylvania line and Portsmouth, Ohio. A report on each of these industries, identifying specific products, developmental patterns, and overall importance as measured by the number of people employed, capital investment, and value of product was prepared. Quite by chance I undertook the research report on the iron and steel industry. Since I was familiar with the past of the upper Ohio Valley, at least the local rural traditions and the county histories, I was surprised to find that the steel works in and around Wheeling, West Virginia, and Steubenville, Ohio, had their beginnings as nail mills. Moreover, I discovered that these nail mills, after the mid-nineteenth century, were not only the largest in the country but also were almost two times as efficient as competitors in the East. Having learned this I decided to explore the origin and development of nail manufacturing in more depth. Assuming that the Wheeling mills had obtained some technological advantage, I began my research with the technology of nailmaking. After examining both iv secondary and primary sources, I concluded that this assumption was incorrect. Instead of new technology, business structure and technique applied to the technology appeared to be responsible for the rise of the Wheeling firms to leadership in the industry. What had begun as a technological study was transformed into and completed as a business history with an emphasis on the relationship between management practices and technology. In order to study the Wheeling firms effectively it was necessary to examine the history of the cut nail in general. I have included a chapter on the development of the cut nail before 1833, the date taken as the founding of the first Wheeling nail firm. This period deserves a more comprehensive treatment than is possible in connection with the technology of nail manufacturing in the Wheeling area because it was in the era between 1776 and 1832 that the great technological advances were made. Throughout much of the study nail manufacturers outside of Wheeling are noted for comparison and context. Most conspicuous are those firms located in and around Pittsburgh, but occasional reference is made to Eastern firms. Since there is no comprehensive history of nail manufacturing, the information on both the early history of nail­ making and the firms outside of Wheeling may be of some use to researchers who have an interest in the general history of cut nail manufacturing. v VITA January 8, 1945 .................

This paper presents experimental testing and validation of the major subsystems in a microscale selective laser sin- tering (l-SLS) process that is capable of fabricating true-3D metallic micro- architectures with microscale feature size resolutions. In l-SLS, the part quality and throughput of the sintering process are largely determined by the precision, accuracy, and speed of the subsystems including: (1) the optical subsystem, (2) the global positioning mechanism, (3) the XY nanopositioning stage, and (4) the powder bed dispensing system. This paper shows that each of these subsystems can maintain the sub-micrometer precision and accuracy required to produce metal parts with microscale resolutions. Preliminary sintering results with optimized process parameters show the potential of the l-SLS process to fabricate complex metal parts with sub-10- lm resolution at high rates.
