Within the framework of a more extensive study of the high stress exponents and high activation energies which characterize deformation in particulate composite materials, powder metallurgically produced Zn-Al//2O////3 composites containing 5, 15, and 30 vol% 0. 3mu alpha-Al//2O////3 particles were tested in compression at different strain rates, at up to 400 C. Results are compared with those for pure zinc. Conclusions are drawn concerning the effects of particle size and volume fraction of second phase on the flow mechanism.

United States Naval Applied science Laboratory has been installing and retrieving deep sea mooring installations in southeastern part of Tongue of Ocean (TOTO), Bahamas since 1965;conventional moorings, such as vertical "taut-wire" rope moorings, as well as moorings of more complex design have been used to expose variety of metallic and nonmetallic materials;because of loss of one mooring, multiple recovery systems was designed;new array, materials under exposure, and operations connected with installation are described.
