Protonic defects in oxides and their possible role in high temperature oxidation
Protons from hydrogen or water vapour may dissolve in oxides and other corrosion products, and may affect, and in some cases, dominate their defect structures. Defect-dependent properties like scale growth and plastic deformation then become dependent on the ambient hydrogen or water vapour pressure. Small concentrations of protons may enhance the transport of oxygen in the form of hydroxide io...
متن کاملTHE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES
AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...

متن کاملSurface-enhanced Raman scattering at elevated temperatures.
The effect on surface-enhanced Raman scattering due to the increase in temperature of the metallic substrate is studied via a simple model for physisorbed molecules. Surface roughness is represented by a spherical or spheroidal island, and the temperature effects on the surface plasmon are accounted for via a slightly modified Ujihara model. It is found that the enhancement ratio in general dec...
