Book Description
A comparison of the stress corrosion cracking (SCC) susceptibility of four aluminum-zinc-magnesium alloys was determined as a function of processing and composition variables, particularly aging treatment and titanium additions. The SCC tests were performed employing a four point loaded constant moment apparatus in a 3.5% sodium chloride solution at room temperature. The alloys were studied as part of a microstructure and microcomposition characterization program in order to determine the effect of these variables on the SCC susceptibility and mechanical properties of the Al-Zn-Mg system. (Modified author abstract).

Book Description
The report summarizes information from selected European papers and lectures that were published or presented between mid 1967 and July 1, 1968. Subjects discussed include: the nature of stress-corrosion, stress-corrosion in AlMg, AlMgZn, and AlMgSi alloys and testing for susceptibility to stress-corrosion cracking. (Author).

Book Description
The characteristic susceptibility to stress-corrosion cracking exhibited by certain titanium and many aluminum alloys was studied. Mechanisms germane to establishing the conditions for stress-corrosion cracking in heat-treatable alloys during precipitation hardening are covered. A 7075 A1 alloy and an A1-Zn-Mg ternary alloy were used in construction of a stress-corrosion model. The model showed that the stress corrosion cracking susceptibility of A1 alloys becomes reduced if one or more of the following can be realized: (1) elimination of the precipitation-free zone, PFZ, through proper heat treatment; (2) inducement of the formation of primary precipitates in the PFZ to enhance hardening; (3) inducement of the segregation of solute atoms to produce sufficient grain boundary hardening into the PFZ; (4) reduction of the PFZ width to a practical minimum; and (5) addition of an additive such as Cd, Sn and In to initiate precipitation of CuAl2 in the PFZ during initial aging. The resistance to stress-corrosion cracking will be increased because of: (1) the virtual elimination of the difference in mechanical properties between the PFZ and the train interior due to differences in thermal history, and (2) due to the presence of Cd, the reduction of the anodic effect at the grain boundaries.

Book Description
Treatise on Materials Science and Technology, Volume 28: Materials for Marine Systems and Structures provides an integrated approach, utilizing the environmental information of the ocean scientists, materials science, and structural integrity principles as they apply to offshore structures and ships. The book discusses the materials and their performance in marine systems and structures; the marine environment; and marine befouling. The text also describes marine corrosion; corrosion control; metallic materials for marine structures; and concrete marine structures. Materials for mooring systems and fracture control for marine structures are also considered. Professional scientists and engineers, as well as graduate students in the fields of ocean and marine engineering and naval architecture and associated fields will find the book useful.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis, (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 19 (thesis year 1974) a total of 10,045 theses titles from 20 Canadian and 209 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 19 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
