Book Description
Tensile property measurements and fractographic analysis of S-65C beryllium are reviewed. Tests were performed on specimens oriented in the longitudinal and transverse directions with respect to the direction of vacuum hot pressing. Specimens were tested in air at RT, 100 C, 200 C, 300 C, 415 C and 500 C at an initial strain rate of 1.1 x 10−4 per second. Ductility of the material was strongly affected by the test temperature, exhibiting a peak ductility at 300 C. The material displayed a yield point phenomenon which was most pronounced at this same temperature. Scanning electron microscopy was performed on the resulting fracture surfaces and observations are reported.

Book Description
This book introduces beryllium; its history, its chemical, mechanical, and physical properties including nuclear properties. The 29 chapters include the mineralogy of beryllium and the preferred global sources of ore bodies. The identification and specifics of the industrial metallurgical processes used to form oxide from the ore and then metal from the oxide are thoroughly described. The special features of beryllium chemistry are introduced, including analytical chemical practices. Beryllium compounds of industrial interest are identified and discussed. Alloying, casting, powder processing, forming, metal removal, joining and other manufacturing processes are covered. The effect of composition and process on the mechanical and physical properties of beryllium alloys assists the reader in material selection. The physical metallurgy chapter brings conformity between chemical and physical metallurgical processing of beryllium, metal, alloys, and compounds. The environmental degradation of beryllium and its alloys both in aqueous and high temperature condition are presented. The health and environmental issues are thoroughly presented the current requirements and established practices for handling beryllium in the workplace are available. A thorough list of references will assist the user of this book.

Book Description
The elevated temperature tensile properties of hot-pressed QMV beryllium have been studied from 250-950°C. Also those of warm-pressed, hot-extruded beryllium have been investigated from 250-600°C. Both materials exhibit a ductility peak at about 450°C while tensile strength decreases with increasing temperature. The results are compared with data reported in the literature on extruded flake and extruded cast beryllium. Special equipment developed for tensile testing beryllium up to 950°C is illustrated and described.

Book Description
The purpose of this program was to study the effect of high strain rates and elevated temperatures on the mechanical properties of three grades of beryllium: S-200, I-400 and Ingot Sheet. Uniaxial tension and compression tests were conducted at strain rates of .001 to 1000/per sec. The test temperatures ranged from 72 to 700 F. This report includes a literature survey and a discussion on the problems encountered during testing in addition to the presentation and discussion of results. The influence of oxide content, grain size, and fabrication history on the strain rate sensitivity and other mechanical properties of beryllium is examined. (Author).
