Complex two-component peak of anelastic mechanical losses was observed in multicomponent substitutional austenitic alloys after prior plastic deformation. In AISI 316L, AISI 316LN, AISI 310 and AISI 304 austenitic stainless steels, this peak is situated in the wide range of temperature from 200 to 400K. Characteristics of the observed peak for different thermo-mechanical treatments were studied...

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...

behaviors of stress corrosion cracking (scc)in martensitic stainless steel(aisi 420) and low carbon austenitic stainless steel (aisi 316l) have been compared under different conditions of temperature, environment (mgcl2), and strain rate. the results show that decreasing strain rate has detrimental effect on mechanical properties of both steels, including their strength and ductility. fractogra...

In this investigation, MoSx/Cr coatings were deposited by direct-current magnetron sputter onto Ck45 (AISI 1045) plain carbon steel substrates. The MoSx/Cr ratio in the coatings was controlled by sputtering the composite targets. The chemical characterization was performed using EDX (energy dispersive X-ray analysis); the structural characterization was accomplished by X-ray diffraction (XRD) s...

Mechanical machining processes are common manufacturing strategies to re-shape materials to desired specification. The mechanistic approach has revealed the mechanics of the machining processes with various parameters determined. The aim of this work is to investigate the impact of swept angle optimization and their influence on the specific cutting energy in milling AISI 1045 steel alloy. This...

Coatings by physical vapor deposition (PVD) have become highly relevant due to their wide range of applications and the rapid rate coating formation. In this work, AISI steel 1045 was coated with two layers, Ni Co using PVD technique. Each deposited a thickness 1 ?m. After applying coatings, post-treatment applied in an AC plasma reactor boron nitride blank Ar atmosphere at pressure 3 Torr, 0.3...

The electrical discharge machining (EDM) process is mostly used in conditions that complex and intricate shapes need to be machined on very hard metals. However, the leaves behind some undesirable properties such as high surface roughness, rough topography, residual tensile stresses, micro-cracks, heat-affected zone (HAZ), recast layer. This paper investigates effects of different output parame...

In this study, deep learning approach was utilized for fatigue behavior prediction, analysis, and optimization of the coated AISI 1045 mild carbon steel with galvanization, hardened chromium, nickel materials different thicknesses 13 19 µm were used coatings afterward related specimens achieved via rotating bending test. Experimental results revealed life improvement up to 60% after applying ga...

The present work is concentrated with the dry turning of AISI 304 Austenitic Stainless Steel (ASS). This paper presents the influence of cutting parameters like cutting speed, feed rate and depth of cut on the surface roughness of austenitic stainless steel during dry turning. A plan of experiments based on Taguchi’s technique has been used to acquire the data. An orthogonal array, the signal t...
