Electromagnetic sheet forming is a high-velocity process that the strain rate is considerable. The formability of the material increased in the high strain rate process. In this study, an Al/Cu two- layer sheet’s formability at a high strain rate is investigated using electromagnetic forming. The two-layer sheet produced by the explosive method was used to create different geometry and different strain states in the experimental test. The necking strain was extracted by griding the sheet. The coil is designed to create enough pressure to reach the fracture in the sheet. The driver sheet is also used to create more pressure on the workpiece. The displacement of the sheet and the strain distribution were investigated in a different geometry with different widths. The magnetic pressure is 19% higher in the CA lay-p (Cu near the coil and Al..... ReadMore

Recent development of fabrication methods of porous metals with open channels are introduced. Open-channel aluminum was fabricated by extracting template wires coated with lubricant out of solidified aluminum. The lubricant serves as a diffusion barrier between template wire and its surrounding aluminum. The penetration ratio of the through-holes is 100%. The hole size, hole length and porosity are uniquely controlled by thickness, length, and the number of template metallic wires, respectively. The methodology for producing the open-channel metals is expected opportunities for application technologies such as functional materials like heat sinks, heat exchangers, shock absorbing materials and light-weight structural materials......

In this work, we investigate the formation/decomposition boundaries in the P–T phase diagram of the magnesium hydrides. The formation/decomposition boundaries are obtained based on the Gibbs free energy determined by DFT and CALPHAD calculations for the most stable polymorphs of magnesium hydride (α-MgH2, γ-MgH2, and ε-MgH2), of the hcp polymorph of the crystalline magnesium, and of the hydrogen gas (in the real gas model) in the pressure and temperature ranges 0-10 GPa and 0-1200 K, respectively.....

One of the limitations associated with response surface methodology (RSM) is that an understanding of the trend and pattern of the input variable is required for every model. It means therefore that the performance of RSM is dependent on the beauty of experimental design. Therefore, to predict the response variables beyond the scope of experimentation, predictive model such as artificial neural network (ANN) is required. The focus of the study is to apply artificial neural network for the prediction of tig process parameter such as Brinell hardness number (BHN), heat input (HI) and cooling rate (CR) which is required for eliminating post weld crack formation, and stabilizing heat input in mild steel weldment. The key input parameters considered in this work are welding current, welding voltage and welding speed while the response or measu..... ReadMore

Organic fluorescent compounds are playing and will play an important role in scientific research in the next decades owing to their potential technological applications in the fields of chemo sensors, biological imaging, and optical evices [1]. With hundreds of metal-free dyes published every year an immediate question arises: is there any room for new organic fluorophores? To find an appropriate answer, we should analyze the present and past of organic fluorophores. On one hand, conventional organic fluorophores like pyrene, anthracene, or perylene are essentially non-fluorescent in the solid-state, which limits their usage in practical applications.....

With recent renewal interest in survivability, radiation hardening against cold or hot x-ray as well as high power laser energy among defense companies and military communities, radiation shielding of military equipment becomes an imperative task and requirement. Materials used in radiation shielding is one way to go to protect any vulnerable digital circuits in form of an integrated circuit, and consequently selecting of such ICs for a radiation environment also becomes a necessity as part of survivability requirements. Thermomechanical properties of materials as part of shielding are also going to play a huge role as part of protection of these ICs as well. With most countries getting involved with their nuclear arsenal development, protection of our assets in space or on ground such as electric circuits and grids is another issue that ..... ReadMore

The light surface heating/cooling system (LSH/CS) creates a structure in which the surface of the thermal insulation is very often covered with metal heat diffusers. These are steel sheets, aluminum sheets, or aluminum foils with various thicknesses. Different types of floors are glued directly to them, no required screeds. For this purpose, you can use various types of adhesives dedicated by manufacturers to glue the thermal insulation layer with aluminum foil or metal heat diffusers with the floor. The most important parameter of the glued layers is their strength perpendicular to the face. It may depend on the influence of the temperature. To check this, various types of adhesives were tested by being put between thermal insulation and a layer of aluminum foil, between tiles and foil heat diffusers, as well as tiles and XPS boards with.....

A new Mg-7.28Li-2.19Al-0.1Y alloy has been fabricated by rolling, and the rolled and annealed sheets were subjected to laser surface treatment. The microstructure and mechanical properties were investigated. The rolled alloy demonstrates ultimate tensile strength (UTS) of 299.48 MPa and elongation-to-failure (EL) of 15.71%; the annealed alloy demonstrates the UTS of 211 MPa and EL of 26.5%; laser treated rolled sample exhibits the UTS of 215 MPa and EL of 21.96%, and laser treated annealed sample exhibits the UTS of 205 MPa and EL of 19.15%. Laser treatment refines significantly the grains of Mg-7.28Li-2.19Al-0.1Y alloy, but laser treatment does not improve its mechanical properties due to its role of softening in the present alloy. The laser treatment softening phenomenon in this alloy is the first report of laser treated Mg-Li alloy..... ReadMore

In this work, a nanostructured TiC powders were produced by mechanical alloying (MA) through high energy ball milling from a mixture of elemental powders of titanium (Ti) and graphite (C) in argon atmosphere. MA process was performed for 20 h in a planetary ball mill (Fritsch Pulverisette 7) at room temperature at a ball-to-powder weight ratio of 70:1. Microstructure and morphology of the samples were investigated by using X-ray diffraction (XRD), laser granulometry, scanning electron microscope (SEM), and transmission electron microscope (TEM). XRD studies revealed that in the times more than 15 h of MA all the raw materials were changed to the desired materials. Results showed that nanocrystalline TiC, with about 10 nm, is synthetized by reaction between Ti and C atoms...... ReadMore

Both pure silica (SiO2 ) nanoparticles (SNPs) and functionalized hybrid triclosan (TCS)/silica nanocomposites (T-SNCs) were deposited onto nonfunctional Parylene C films using a novel, readily executed, one-step decoration method. Unlike previously known methods, this functionalization method of Parylene C films required neither any binding agent nor sophisticated equipment/ devices. The SiO2 -based NPs anchored onto Parylene C substrates were formed via a common base-catalyzed hydrolytic sol-gel method. Regarding the mechanism, it has been assumed that the SiO2 phase precursor (Si(OC2 H5 )4 ), tetraethoxysilane (TEOS), was first adsorbed and 2D polymerized onto the parylene C film due to hydrophobic interactions that served as an anchor mechanism for further corresponding NPs growth [1] This assumption was investigated by co.....

Currently, lots of research work have been conducted to exploit inorganic optical storage materials (OSMs). Despite those impressing discoveries of new OSMs, the inducing of defects or traps and the interaction between light-emitting center and charge carrier recombination center is still under debate. Herein, through sol-gel methods, a novel Ba1-xMg2 Al6 Si9 O30: xEu (BMASO: xEu) phosphor of OSMs were successfully synthesized. Fine crystallization of hexagonal phase was proved by XRD Rietveld refinement. From the thermoluminescence (TL) results, a super-broad distribution of trap level from 323-673 K was found for the sample BMASO:0.02Eu annealed in a reductive atmosphere, with a considerable TL intensity even in a high temperature region over 673 K. Because of the annealing in reductive atmosphere and part of Eu ions replacemen..... ReadMore
