Abstract: Thermo-elastoplastic finite element methods are used to investigate the thermal cycling of SiC whisker-reinforced aluminum-matrix composites. In a previous investigation, the development of residual ...

Abstract: The microstructure of H2 S-O2 flames has been developed in terms of composition and temperature profiles. With the aid of these profiles, rates of formation of SO2 and SO3 are reported and ...

Abstract: Fe2 O3 -, Fe3 O4 -, NaOH-Fe2 O3 -, and NaOH-Fe3 O4 -coated substrates of Vycor and of iron were exposed to controlled gas mixtures containing SO2 and SO3 . Sulfate and sulfide formation ...

Abstract: Radioactive sulfur-35 has been used as a tracer to determine the roles of SO2 and SO3 in reactions leading to formation of alkali iron trisulfates. The reactivity of 30 ppm SO3 with surfaces ...

Abstract: The reactions of SO2 and SO3 with catalytic surfaces containing iron oxides, alone and in combination with various sodium salts, have been investigated. The SO3 concentration gradients above the ...
