Abstract: The results of this paper relate to a development program designed to improve the corrosion resistance and mechanical properties of Al-2.5Mg alloys, by the addition of chromium and silicon, for ...

Abstract: Particle accelerator based μ-PIXE and μ-RBS techniques along with optical microscopy, SEM and EDS were employed to examine the worn faces of uncoated tungsten carbide inserts used for cutting ...

Abstract: The tube-to-tubesheet joint strength is measured in terms of interfacial pressure between the tube’s outer surface and tubesheet bore. The strength of a rolled joint is influenced by several ...

Abstract: An experimental study has been conducted to evaluate the effect of roller expansion of heat exchanger tubes in enlarged tubesheet holes on joint strength, tube wall reduction (i.e., thinning), ...

Abstract: This paper presents the results of an experimental investigation conducted to evaluate the effect of initial tube-tubesheet diametral clearance on the integrity of roller-expanded tube-to-tubesheet ...

Abstract: Heat exchanger tube rolling introduces tensile residual stresses in the expanded part of the tube and the transition zone between the expanded and unexpanded regions of the tube. These tensile ...
