...Grégory Mertz; Fatima Hassouna; Valérie Toniazzo; Abdesselam Dahoun; David Ruch The effect of coated rutile titanium dioxide (TiO 2 ) and a disazopyrazolone dye (azo dye) on the mechanism and the kinetic of photo-oxidation of unvulcanized styrene butadiene rubber (SBR) composites under accelerated...

...L. G. Zhao Finite element analyses of oxygen diffusion at the grain level have been carried out for a polycrystalline nickel-based superalloy, aiming to quantify the oxidation damage under surface oxidation conditions at high temperature. Grain microstructures were considered explicitly...

...W. Gan; K. Okamoto; S. Hirano; K. Chung; C. Kim; R. H. Wagoner Friction-stir welding (FSW) promises joints with low porosity, fine microstructures, minimum phase transformation, and low oxidation compared with conventional welding techniques. It is capable of joining combinations of alloys...

... phase, with oxidation and dissolution of W C ∕ W 2 C taking place. Also potentiostatic tests indicated that the corrosion of WC-based coatings follows an Arrhenius relationship enabling the determination of activation energy ( E a ) for the corrosion of WC and demonstrating that the oxidation...

...K. V. Pochiraju; G. P. Tandon This paper describes modeling of degradation behavior of high-temperature polymers under thermo-oxidative aging conditions. Thermo-oxidative aging is simulated with a diffusion-reaction model in which temperature, oxygen concentration, and weight-loss effects...

.... In this paper, a computational micromechanics study is conducted to obtain high-temperature constitutive properties of the PMC undergoing simultaneous thermal oxidation reaction, microstructural damage, and thermomechanical loading. The computational micromechanics approach follows the recently developed...

...C. L. Briant The use of refractory metals as high temperature structural materials has been limited in the past because of the rapid oxidation and low creep strength of the metals. Recently, a number of advances have been made in which alloying additions have improved these properties. This paper...

..., there are a number of unknowns associated with the failure of TBC systems. In particular, the initiation and propagation of damage has not been observed. In this paper, the microstructural changes in and along the thermally growth oxide layer of a TBC are presented. Specimens were studied primarily after isothermal...
