Density measurement for corrosive solutions at elevated temperatures

Measurement of Ultrasonic Velocity and Attenuation at Elevated Temperatures

Ultrasonic non-destructive testing is a sensitive tool not only for defect detection and evaluation in plant components and structures, but also to characterise microstructural features and for evaluation of mechanical properties. Even though, it provides high sensitivity and reliability for such measurements and very versatile to use at ambient temperatures, the technique fails when it is exte...

THE 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 ...

Application of T-shape Friction T test for Ti-6Al-4V Alloy at Elevated Temperatures

There are several parameters that have significant influence in metal forming process. One of the most important of them is friction coefficient. Friction can change the pattern of metal flow and the force needed for deformation. It is necessary to determine the friction coefficient to study the effect of friction on metal forming process. This study is concerned with numerical and experimental...

Surface-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...
