Bauschinger effect in uranium. [Rarefaction waves]

Description: The Bauschinger effect (different elastic-plastic behavior upon unloading) was measured in uranium and a model of the effect developed for use in one-dimensional hydrodynamic codes. Results from plate-impact tests show that rarefaction waves in uranium can be calculated more accurately with this model. We conclude that the Bauschinger effect can be an important aspect of rarefaction waves in uranium and other materials. 8 figures. (auth)

Web-dendritic ribbon growth. Quarterly report, 1 January 1976--31 March 1976. USC solar report No. Q-2

Description: The purpose of this investigation is to develop web-dendritic process methods that will: (1) minimize the cost of processing silicon into ribbons of solar cell quality with a terrestrial energy conversion efficiency greater than 10 percent, and (2) be suitable for large quantity production. The report for this second quarter describes the work of the program during this period and presents the plan for the program for the full length of the contract. Work is described on: (1) the procedures use… more

TATB formulation study

Description: Small-scale production and mechanical properties of TATB/Kel-F 800 (92.5/7.5), a useful plastic bonded explosive, are described. TATB particles are slurried in water while adding a solvent solution of Kel-F. As the solvent is removed from the slurry at 75 to 80/sup 0/C under vacuum, the fine particles of TATB become coated with Kel-F and clump together to form granules. After drying at 80/sup 0/C the granules are pressed at 120/sup 0/C and 138 MPa (20,000 psi) to form needed shapes.
