To upgrade the performance of welded joints the various improvement methods are used. Shot peening is one of the improvement method used to strengthen the properties of welded joints. GMAW process is very well suited for welding of AISI 304 austenitic stainless steels. Regression analysis is the statistical modeling technique, and it is suitable for the majority of predicting problems. It is va...

The oxidation of stainless steels 304 and 304L during hot rolling is studied in this paper. Results show the oxide scale thickness decreases significantly with an increase of reduction, and the oxide scales of both 304 and 304L stainless steels were found more deformable than the steel substrate. Surface roughness shows a complicated transfer during the hot rolling process due to the complexity...

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...

An Al-40.0Ge-3.4Si wt.% alloy foil with a thickness of 50 ± 5 μm, obtained via an ultrafast solidification method, is described in this work. A complete wetting the aluminum substrate angle 0° observed, and formation drop 30 5° observed on steel substrate. Similar dissimilar brazed joints AA 6082 stainless-steel AISI 304 are obtained. The microstructure 6082/AA seam homogeneous contains particl...

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...

INTRODUCTION Contaminated sponges might lead to cross-contamination in kitchens since they can transfer microorganisms to surfaces where microorganisms can survive for hours or days and contaminate food. The main objective of this study was to evaluate the transfer and the survival of bacteria from kitchen sponges to surfaces of AISI 316 stainless steel and polyethylene. METHODOLOGY Twenty-fo...

In this research work a series of tests were conducted in order to determine flank wear and cutting force FY on hard AISI 440 C martensitic stainless steel and SCM 440 alloy steels. The operating parameters are cutting speed, feed rate and a constant depth of cut to investigate the flank wear and cutting force. No cutting fluid was used during the turning process. The cutting tool used was CBN ...

The effect of several Almen intensities of shot peening on the corrosion behavior, surface roughness, micro hardness profiles, and residual stresses of stainless steel AISI 316 L were investigated. Hydroxyapatite coating (HA) were applied to shot peened materials to improve their corrosion resistance. The corrosion behaviour were studied using potentiodynamic polarization. The electrochemical t...
