An artificial neural network (ANN) model is developed for the analysis, simulation, and prediction of the austenite reversion in the thermo-mechanical treatment of 304L austenitic stainless steel. The results of the ANN model are in good agreement with the experimental data. The model is used to predict an appropriate annealing condition for austenite reversion through the martensite to austeni...

Electron beam welding has proved phenomenal in welding of components used in space because it uses a vacuum environment which eliminates substances like oxygen, nitrogen, and hydrogen. The main advantage of EBW is its ability to weld dissimilar materials and incorporate desirable properties in the assembly. It has high depth to width ratio and focuses exactly on the portion to be welded, thereb...

As the structure of biofilms plays a key role in their resistance and persistence, this work presents for the first time the numerical characterization of the temporal evolution of biofilm structures formed by three Listeria monocytogenes strains on two types of stainless-steel supports, AISI 304 SS No. 2B and AISI 316 SS No. 2R. Counting methods, motility tests, fluorescence microscopy and ima...

Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...

INVESTIGATING THE EFFECT OF WELDING PASTE CONTAINING GRAPHENE NANOSHEETS ON BONDING PROPERTIES WELDED AISI 304 STAINLESS STEEL PRODUCED BY FLUX-CORED ARC

It is well known that during tensile testing, a part of the mechanical work done on the specimen is transformed into heat energy. The rate of rise and maximum temperature attained depends on the nature of material, its deformation behaviour and test conditions. This paper highlights the application of thermography for characterising various stages of tensile deformation in AISI type 316 stainle...

The corrosion and cell viability behaviors of nanostructured, nickel-free stainless steel implants were studied and compared with AISI 316L. The electrochemical studies were conducted by potentiodynamic polarization and electrochemical impedance spectroscopic measurements in a simulated body fluid. Cytocompatibility was also evaluated by the adhesion behavior of adult human stem cells on the su...

the mechanical properties and microstructural developments of 321 stainless steel during thermomechanicalprocess were investigated. the repetitive cold rolling and subsequent annealing wereconducted to achieve nanocrystalline structure in an aisi 321 stainless steel. heavily cold rolling at−20°c was conducted to form martensite in metastable austenitic steel. the process was followed byannealin...
