The elastic properties of copper have been compiled and reviewed. Polycrystalline elastic constants included are: Young's modulus, the shear mociululO, the bulk modulm, and PoislOon's ratio. Single·crystal constantlO of second·, third., and fourth·order are included. Over 200 refer· ences to the experimental literature are given. A few theoretical numbers are included. When suffieient data exist, hest values are recommended together with their standard errors. Effects on the elastic constants of tf'mperature, pressure, and mechanical (plastic) deformation are in· cluded. The Cauchy (central·force) relationships and the single·crystal-polycrystal relationship are also discussed.

Superduplex stainless steels (SSS) composed in both equal fraction ferritic-austenite phases, classically defined by ASTM A995M Gr.5A, in order to obtain a better relation of mechanical properties and corrosion properties, are applied as components for use in petrochemical industries in off-shore platforms. The corrosion resistance of stainless steels is due to the oxides formed on the surface, which is dependent on the temperature and environment in which they are exposed. This paper investigates a microstructure duplex during steps of thermal attack under vacuum at high temperatures through observation of the coloration and growth of oxide films. Some coloration was observed in the phases, austenite and ferrite, with the increase of the temperature to 1100 °C, which is indicative of the presence of chromium and iron oxides. In the cooling occurs the stability of oxides present in the films. Electrochemical tests were conducted in H 2 S/CO 2 -saturated in two different concentrations of chloride sodium electrolyte, simulating a seawater environment. Potentiodynamic polarization curves indicate that pitting corrosion resistance and repassivation process in media of 3.5 and 9.0% (wt.%) NaCl are not affected by the presence of H 2 S/CO 2 (40/60 ppm) at room temperature (25 °C).
