摘要
Abstract : The Department of Defense, in 1955, established the Titanium Metallurgical Laboratory at Battelle-Columbus, expanding the scope and changing the name to Defense Metals Information Center in 1958. The Defense Ceramic Information Center was assigned to Battelle in 1967. The two Centers were combined in 1971, forming the current Metals and Ceramics Information Center (MCIC). This is the first annual report on the new MCIC program, but its historical data are derived from the 17 continuous years of these DoD information service activities. During the contract year reported, 3247 references were added to the approximately 100,000 items in the MCIC files. 580 technical inquires were processed (more than 80% of these before the introduction of inquiry charges). 61 issues of the Reviews of Metals and Ceramics Technology were published; the Reviews now are sold under subscription through NTIS. 9 formal state-of-the-art reports were published; and three new Handbook programs were initiated. Several special studies were conducted and the operations of MCIC were converted totally to the computerized system which was initiated in 1970. Arrangements were implemented for use of National Technical Information Service for marketing MCIC output.
