This report is a guide to the literature on high-velocity metalworking. It consists primarily of abstracts of articles, reports, books, and current research projects on and related to high-velocity metalworking arranged according to technical subject. It covers a survey of the reported work in the field up to about October of 1962. Abstracts of over 700 references have been arranged by subject matter, with cross indexing between subjects. There is also an author index. The eleven major subjects and categories covered in the report are: (1) Energy Sources, (2) Energy Transfer Mediums, (3) Facility Requirements, (4) Tooling Requirements, (5) Equipment Requirements, (6) Forming, (7) Hardening, (8) Explosive Welding, (9) Powder Compaction, (10) Metal Removal, and (11) Material Behavior.
To aid in quick identification and easy location of specific technical data and information in the various reports and memoranda which have been prepared and distributed by the Defense Metals Information Center, as well as by DMIC's forerunner, the Titanium Metallurgical Laboratory, a classification by major subject matter was prepared. The classification covers reports through DMIC Report 193 and memoranda through DMIC Memorandum 183. (Author).
Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.
Tensile properties that may be obtained in highstrength alloys for use from -423 to 4000 F are presented. Representative properties are given for high-strength alloys of the common base metals having melting points from that of Mg to that of W. The primary purpose is to illustrate the upper limits of the yield strength to density ratios for these alloys within the range of possible service temperatures. The temperature and time effects are combined in the LarsonMiller parameter for 0.2% offset yield strength or 0.2% plastic creep strain for limited creep data. The time for 0.2% offset yield strength determination is assumed as 0.01 hr. This permits use of yield-strength data from tensile tests and 0.2% plastic-creep-strain data from creep tests in the same charts. The LarsonMiller parameter may not be strictly applicable for certain alloys. In some instances, the data are for current production alloys with standard heat treatments. (Author).
