the aisi 316 l stainless steel (ss) specimens were exposed to passivation surface through two different processes including; holding in 40-vol% hno3 at temperature of 60 ºc for 30 min and 15-vol%h2so4 at ambient temperature for 1 hour. the corrosion behavior of specimens was evaluated in physiological solutions by electrochemical in vitro tests through linear and tafel polarization tests. cycli...

In machining, due to the tool vibration the forces, temperatures and stresses vary during the cutting process, so as the residual stresses over the machined surface. This variation of the residual stress has never been measured and, therefore, imposes new experimental challenges. The objective of this work is to correlate the variation of the residual stresses along the cutting path with the fr...

Over the past few decades, there has been a growing interest in modelling of machining processes. In this regard, smoothed particle hydrodynamics (SPH) is one of the latest methods used for that purpose. SPH is a powerful technique that can be used in handling problems of large deformation that are difficult to be tackled using traditional finite element methods. The current work aims to presen...

Pore formation remains a concern in the area of rapid manufacturing by the Laser Engineered Net Shaping (LENS) process. Results usually conflict on the origin of these pores; whether it should stem from an effect due to the physical/mechanical properties of the material or from an effect purely related to the processing parameters. We investigated this problem spanning a range of process parame...

Molten LiCl-KCl salt and liquid cadmium are proposed as the electrolyte reactive cathode for electrorefining of spent nuclear fuels, but they can be corrosive to structural alloys. The down-selection existing materials through corrosion testing is necessary ensure longevity electrorefiner vessel electrode assemblies. Haynes C276, Inconel 600, AISI 316L stainless steel, 42CrMo low-alloy steel we...
