Partial dilution of clad powder and the substrate to form a new protective layer is called as cladding. The present article focuses on development novel surface modification technique for better resistance wear/erosion using microwaves source heat. Clads MoCoCrSi/ WC-Co were produced austenitic stainless steel (SS-316) microwave irradiation techniques. Composite clads established by irradiating...

In this study, Al-Mg-Si alloy AA6061-T6 plates were joined in a seawater environment using the Submerged Friction Stir Welding (SFSW) technique, and process parameters optimized Taguchi L9 orthogonal arrays (OA). The considered tool rotational speed, transverse pin geometry. MINITAB-17 software was used to analyze responses signal-to-noise (S/N) ratio analysis of variance (ANOVA). optimum for t...

For the creation of surface reinforcement particles in metal matrix, friction stir processing is frequently utilized. Formation aluminum/SiC composite on Tungsten Inert Gas (TIG) butt weld Al5083 by a novel technique direct (DFSP) using hollow tool successfully demonstrated this present work. Deposition SiC zone DFSP was confirmed X-Ray diffraction (XRD) method. Micro analysis joint achieved me...

The effects of Bi content as a trace element on the microstructure and solidification path A356.2 alloy have been investigated. alloys containing different levels (0, 20, 200 ppm) modified by sodium. experimental thermally analyzed using two-thermocouple method. Metallographic image analysis techniques used to quantitatively examine microstructural changes occurring at Na concentrations. result...

Purpose. Investigate the effect of complex microalloying with nitrogen, titanium and aluminum on structure properties cast steels at elevated temperatures. Methodology. Methods optical microscopy were used for metallographic analysis microstructure steels. The mechanical room temperatures determined static tension, crease impact bending. Results. technology carbonitride strengthening silicon-ma...

We report analyses of 14 group IVA iron meteorites, and the ungrouped but possibly related, Elephant Moraine (EET) 83230, for siderophile elements by laser ablation ICP-MS and isotope dilution. EET was also analyzed for oxygen isotopic composition and metallographic structure, and Fuzzy Creek, currently the IVA with the highest Ni concentration, was analyzed for metallographic structure. Highly...

Abstract In this work, high-manganese aluminium bronze CuMn 13 Al 7 samples were prepared by arc additive manufacturing technology. The phase composition, microstructure, and crystal structure of the manufactured analysed using direct-reading spectrometer, metallographic microscope, scanning electron transmission microscope. micro-hardness tester, tensile impact electrochemical workstation also...
