Microstructural and mechanical properties of friction stir welded pure lead
(National Institute of Science Communication and Information Resources (NISCAIR), 2018)
The present study focuses on the applicability of friction stir welding to pure Pb plates. The joint performances are evaluated by optical microscopy, microhardness measurements, notch impact tests and three point bending ...
Investigation of the mechanic, electromagnetic characteristics and shielding effectiveness of concrete with boron ores and boron containing wastes
(Elsevier, 2020)
In this study, mechanical properties electromagnetic (EM), and shielding effectiveness of concrete samples containing boron product and wastes was investigated in details. In order to increase shielding effectiveness of ...
Properties and High-Temperature Wear Behavior of Remelted NiCrBSi Coatings
(Springer, 2020)
Remelted NiCrBSi coatings were examined using optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, x-ray diffraction analysis, microhardness and wear testing. After wear tests, the surfaces of ...
Effect of Cr/Sb doping and annealing on nonlinear absorption coefficients of SnO2 /PMMA nanocomposite films
(Elsevier, 2020)
Cr and Sb doped SnO2 nanoparticles were synthesized by hydrothermal method. The structural measurements of as-grown nanoparticles exhibited that the incorporation of the 3% wt. Cr and Sb dopant into the SnO2 crystal structure ...
Comparative experimental study on the modification of microstructural and mechanical properties of friction stir welded and gas metal arc welded EN AW-6061 O aluminum alloys by post-weld heat treatment
(Wiley-VCH Verlag, 2018)
In this paper, the effects of post-weld heat treatment on modification of microstructures and mechanical properties of friction stir welded and gas metal arc welded AA6061-O plates were compared with each other. Gas metal ...
Mutual Coupling Reduction of Cross-Dipole Antenna for Base Stations by Using a Neural Network Approach
(Mdpi, 2020)
In this manuscript, a resonator layer is presented for the purpose of reducing the mutual coupling effect between each antenna element of a cross dipole antenna. In design processes, an artificial neural network approach ...
Effect of Different Arc Welding Processes on the Metallurgical and Mechanical Properties of Ramor 500 Armor Steel
(Asme, 2020)
In the present study, Ramor 500 armor steel plates were automatically welded using cold metal transfer arc welding (CMT), gas metal arc welding (GMAW), and hybrid plasma arc welding (HPAW) methods. To investigate the effects ...
Optimum design of alkali activated slag concretes for the low oxygen/chloride ion permeability and thermal conductivity
