Sixth Generation

This collection chronicles the development of America's favorite sports car by the designers and engineers who made it happen. These 30 papers cover more than 50 years and six generations of the engineering, styling, and research and development of the Chevrolet Corvette. Twenty-two papers focus on the first five generations, with the last eight papers detailing the new sixth-generation Corvette. Material collected in this volume truly has unprecedented historical value. A 1954 paper by Maurice Olley presents a technical description of the first production Corvette. The book's preface includes insight from Zora Arkus-Duntov into the reasons behind the Corvette's development. Other highlights include comments from Corvette's chief engineer, a press release created by General Motors on its fiftieth anniversary, and a timeline with photos documenting the Corvette's evolution.

ABSTRACTGeneral Motors Research and Development and Basell Polyolefins have jointly developed a family of polyolefin-based nanocomposites for use in the injection molding of body-side claddings. Basell Polyolefins commercialized one of these materials as Hifax DX277 in September of 2000, and General Motors has exclusive use of this material. Confidence in the ability of DX277 to perform as intended is being reinforced by molding trials at various Tier 1 locations. In addition to mass savings, the nanocomposite material is showing a much wider processing window than conventional talc-filled TPO’s – allowing Tier 1 molders the opportunity to process away problems rather than initiating a tooling change. This paper will describe the processing advantages associated with the injection molding of a polyolefin-based nanocomposite over a conventional talc-filled TPO.

The conventional distinctions between “practical” and “scientific” research and development can be misleading. The experience of Thomas Midgley, Jr., at the General Motors Corporation in the three decades before World War II, and especially his critical role in the development of “antiknock” gasoline additives, freon refrigerant, and synthetic rubber, illustrate this fact. Dr. Leslie demonstrates that the management of corporate research and development, especially as that management affects uniquely talented individuals whose interests do not necessarily reflect the immediate needs of the company as seen by management, is basic to success. To solve such problems as they arose, Charles F. Kettering, himself a sympathetic scientist as well as distinguished inventor, worked closely with chief executive Alfred P. Sloan, whose genius for solving managerial problems matched the scientific genius of the most brilliant men in the General Motors laboratories.

The paper is dedicated to the 50th anniversary of controlled thermonuclear fusion studies performed at the KIPT on the specific stellarator-type experimental installations commonly referred to as “the torsatron”. Detailed data are reported on the operating thermonuclear facility “Uragan-2M”, the research results obtained with it, and also, the prospects for its use as a reactor. The advantages of the torsatron of this type are described, among them being the wide-range parameter variation capability. This is of importance for finding out the regularities related to plasma stability, heating and confinement.

Mutual Agreement

This program has been organized by the EMSA to commensurate the 50th anniversary of the experimental verification of the wave nature of the electron. Davisson and Germer in the U.S. and Thomson and Reid in Britian accomplished this at about the same time. Their findings were published in Nature in 1927 by mutual agreement since their independent efforts had led to the same conclusion at about the same time. In 1937 Davisson and Thomson shared the Nobel Prize in physics for demonstrating the wave nature of the electron deduced in 1924 by Louis de Broglie.The Davisson experiments (1921-1927) were concerned with the angular distribution of secondary electron emission from nickel surfaces produced by 150 volt primary electrons. The motivation was the effect of secondary emission on the characteristics of vacuum tubes but significant deviations from the results expected for a corpuscular electron led to a diffraction interpretation suggested by Elasser in 1925.

The Way

I do not have access to the abstracts of the first meeting of EMSA but at this, the 50th Anniversary meeting of the Electron Microscopy Society of America, I have an excuse to consider the historical origins of the approaches we take to the use of electron microscopy for the characterisation of materials. I have myself been actively involved in the use of TEM for the characterisation of heterogeneities for little more than half of that period. My own view is that it was between the 3rd International Meeting at London, and the 1956 Stockholm meeting, the first of the European series , that the foundations of the approaches we now take to the characterisation of a material using the TEM were laid down. (This was 10 years before I took dynamical theory to be etched in stone.) It was at the 1956 meeting that Menter showed lattice resolution images of sodium faujasite and Hirsch, Home and Whelan showed images of dislocations in the XlVth session on “metallography and other industrial applications”. I have always incidentally been delighted by the way the latter authors misinterpreted astonishingly clear thickness fringes in a beaten (”) foil of Al as being contrast due to “large strains”, an error which they corrected with admirable rapidity as the theory developed. At the London meeting the research described covered a broad range of approaches, including many that are only now being rediscovered as worth further effort: however such is the power of “the image” to persuade that the above two papers set trends which influence, perhaps too strongly, the approaches we take now. Menter was clear that the way the planes in his image tended to be curved was associated with the imaging conditions rather than with lattice strains, and yet it now seems to be common practice to assume that the dots in an “atomic resolution image” can faithfully represent the variations in atomic spacing at a localised defect. Even when the more reasonable approach is taken of matching the image details with a computed simulation for an assumed model, the non-uniqueness of the interpreted fit seems to be rather rarely appreciated. Hirsch et al., on the other hand, made a point of using their images to get numerical data on characteristics of the specimen they examined, such as its dislocation density, which would not be expected to be influenced by uncertainties in the contrast. Nonetheless the trends were set with microscope manufacturers producing higher and higher resolution microscopes, while the blind faith of the users in the image produced as being a near directly interpretable representation of reality seems to have increased rather than been generally questioned. But if we want to test structural models we need numbers and it is the analogue to digital conversion of the information in the image which is required.
