This invaluable reference provides a comprehensive overview of corrosion and environmental effects on metals, intermetallics, glossy metals, ceramics and composites of metals, and ceramics and polymer materials. It surveys numerous options for various applications involving environments and guidance in materials selection and substitution. Exploring a wide range of environments, including aqueous and high-temperature surroundings, Environmental Effects on Engineered Materials examines specific material-environmental interactions; corrosion rates and material limitations; preventive measurements against corrosion; utilization of older materials in recent applications; the use of new materials for existing equipment; and more.

Several thermal diffusivity disc samples of high purity CVD-SiC were neutron-irradiated to equivalent doses of about 5-8 dpa-SiC at temperatures from 252 up to 800 C. For this temperature range, the degradation in the thermal diffusivity ranged from about 95 percent down to 89 percent, respectively. The reciprocal thermal diffusivity method was used to estimate the phonon mean free paths and defect concentrations before and after the irradiations for these materials. Even though the CVD-SiC material is an excellent monitor of certain neutron irradiation effects, the degradation in the thermal diffusivity (conductivity) appears to be more than a factor of two greater than predicted by recent theoretical model simulations.

This new second edition serves as a go-to reference on the complex subject of stress corrosion cracking (SCC), offering information to help metallurgists, materials scientists, and designers determine whether SCC will be an issue for their design or application; and for the failure analyst to help determine if SCC played a role in a failure under investigation.

The H2L model was used to critically assess degradation within the individual fiber, fiber coating and matrix components for irradiated 2D-SiCf/SiC composite made with an ICVI-SiC matrix and Hi-Nicalon (Trademark) fabric. The composites were made with either a 1.044-micron ("thick") or a 0.110-micron ("thin") PyC fiber coating and were irradiated in the HFIR reactor as part of the JUPITER 12J (355 degrees C, 7.1 dpa-SiC) or 14J (330 and 800 degrees C, 5.8 and 7.2 dpa-SiC, respectively) series. Laser flash diffusivity measurements were made on representative samples before and after irradiation and after various annealing treatments. The ratio of the transverse thermal conductivity after to before irradiation K(sub-irr)/K(sub-zero) determined at the irradiation temperatures and predicted by the H2L model were: 0.18, 0.23 and 0.29 for the 330, 355 and 800 degrees C irradiations, respectively. Thermal diffusivity measurements in air, argon, helium and vacuum indicated that physical separation of the fiber/matrix interface was minimal after the irradiations, but was significant after annealing irradiated composites to 1200 degrees C. These results suggest that during irradiation to 6 dpa or more radial swelling of the PyC interface would compensate for the radial shrinkage of the Hi-Nicalon (Trademark) fiber and the SiC matrix swelling. The fiber shrinkage is due to irradiation-induced grain-growth and recrystallization and the matrix swelling is due to accumulation of irradiation-induced point defects. However, when the irradiation induced swelling in the matrix and fiber coating components was removed by recombination of point defects during high temperature annealing there was significant fiber/matrix separation.
