Mn–Co alloys were electroplated on AISI 430 stainless steel using an electrodeposition technique with the aim to reduce oxidation and chromium volatilization. The electroplating parameters designed improve coating quality. increased current density decreased MnSO4 content resulted in a denser layer. A sample coated 0.10 M CoSO4 0.50 at 350 mA cm−2 showed best resistance after being oxidized 800...

Energy dispersive X-ray Fluorescence technique has been used to study five rupee indian coins of years 1992,1993,1994,1999,2009,2010,2011 and 2012 for their material/ elemental compositions. EDX-720 spectrometer provided with X-ray tube and Si(Li) detector having energy resolution 165 eV at 5.9KeV Mn K X-ray. Different metal compositions like Cupro-Nickel, NickelBrass and Ferritic Stainless-Ste...

In ferritic stainless steel (FSS), undesirable surface defects of ridging appear during deep drawing. The formation of these defects is attributed to the inhomogeneous distribution of orientations of individual grains. In the present work, a new electron backscattered diffraction R(α)-value map was introduced, and the dependence of the tensile directions on the formation of ridging in an FSS sh...

aisi 304l austenitic stainless steel with different grain sizes of 0.5 -12 μm was obtained through the martensiticprocess. corrosion behavior of different samples was investigated in a 0.5m hcl solution using open circuitpotential, potentiodynamic polarization and electrochemical impedance spectroscopy tests. also, the correlationbetween the grain size and pitting corrosion resistance was asses...

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...
