The new type SFG HSS (super fine grain, high strength steel sheet) has been developed by adding solid-solution strengthening elements to conventional IF steel such as Si, Mn. The precipitation behavior of the second phase particles was observed and studied by a carbon extraction replica technique used transmission ele…
The visible-light photocatalytic degradation of an azo dye Reactive Deep Blue K-R by BiOI and BiOCl0.2Br0.1I0.7 photocatalysts was investigated. When the reaction proceeded for 1 h under the conditions of 15mg/l Reactive Deep Blue K-R solution and PH=3, the visible-light degradation degrees of Reactive Deep Blue K-R w…
Finite element method is useful in research of nonlinear problems, and this method has been an obbligato tool in scientific research, engineering design, and product optimization. This paper aims to use finite element method in the study of air-conditioning clothes, for simulating the thermal flux in the microenvironm…
Surface treatment processes are usually applied to improve surface characteristics and resistance. Particularly duplex processes like nitriding combined with nanostructured based coatings are considered as the most advanced ones, with a large application potential in automotive industry. An example is an application i…
In the last years there have been made several studies, involving many materials, with the aim of trying to explain some physical, chemical and mechanical macroscopic properties of these materials, across the study of the free volumes at the atomic and molecular scale. The positron annihilation lifetime spectroscopy (…
In this work, it is reported the characterization of the microstructure and electric properties of ZnO:Al thin films produced by magnetron sputtering. An AZOY sputtering target (98 wt% ZnO + 2 wt% Al2O3) was used as source material. The microstructure, optical and electrical properties of ZnO:Al thin films were invest…
The high strain rate compressive behavior of a bicomponent high performance epoxy resin for advanced composites filled with Polyaryletherketone (PAEK) has been studied on a modified split Hopkinson Pressure Bar (SHPB) setup under dynamic loading conditions. Dynamic stress-strain plot was obtained for each sample. The…
Ag thin films were prepared on the float-glass substrate by DC magnetron sputtering method. The relationship of surface morphology/electrical properties with technical conditions was investigated. The experimental results showed that sputtering power, sputtering pressure and substrate temperature had effects on the mo…
Nanostructured copper-diamond composites can be tailored for thermal management applications at high temperature. A novel approach based on multiscale diamond dispersions is proposed for the production of this type of materials: a Cu-nDiamond composite produced by high-energy milling is used as a nanostructured matrix…
The process of ion nitriding and multi-arc ion plating compound preparation Ti0.33Al0.67N membrane layer, it is the hot research spot of coating technology at present. Under the premise of this process, how to get better performance of thin-film coatings is the focus of research. Based on thin film deposition process…
Micro dimples have been generally considered as a valuable texture which can improve lubrication and reduce wear of the sliding surfaces by acting as reservoirs of lubricants and grinding debris. Laser shock processing (LSP) is an innovative surface treatment technology which can modify metals and shape metallic parts…
A series of ZnIn2S4 photocatalysts were synthesized via a surfactant-assisted hydrothermal method at 120 °C for 6h. The products were characterized with X-ray diffraction (XRD), UV-vis diffuse reflectance spectra (DRS) and field emission scanning electron microscope. The results indicated that the series of samples ha…
Thermal design and thermal analysis of control cabinet for pattern sewing machine was researched to make components’ temperature meets the requirement. Basic flow sheet of research process was introduced. Then, preliminary thermal design and thermal analysis was performed, and the computed result indicated that temper…
The process of the supercavitation projectile penetrating into metal targets was simulated by using the dynamic analysis software ANSYS/LS-DYNA, and the deformation、breakage and forces on the body in different initial velocities and the penetration depth were discussed. Analysis results show that there are two peaks o…
In this Paper, electroless nickel-phosphorus composite of Al2O3 deposit is prepared by chemical plating on 45 steel. Surface topography, microstructure and major elements are analyzed by SEM, EDS and XRD. The results show that the deposit is compact and the binding of the coating interface is very good. It is found th…
In the present work we have used Physical vapour deposition (PVD) technique followed by thermal annealing to synthesize Ag-soda glass nanocomposite samples. This technique offers a great deal of promise in terms of general simplicity of operation, minimal requirements for sample preparation, ease of adaptation to auto…
Due to its non-crystalline, amorphous structure, glass is particularly susceptible to radiation-induced coloration/discoloration. Oxide glasses reveal a variety of colors depending upon their composition when exposed to high energy radiations such as gamma and X-rays, and the colors induced have been explained in term…
The nucleus orientations and the nucleation sites at the early stage of recrystallization were studied by EBSD analysis in Ti-IF steel during direct annealing after warm rolling. It is concluded that the formation of the recrystallization texture is dominated by oriented nucleation mechanism. The recrystallized nuclei…
The influence of humidity content on the electrical and dielectric properties of a composite made from recycled TetraPak® containers and granulated cork was studied. The material components have been dried before preparation and after the composite was conditioned by keeping the samples in a dry environment (desiccato…
Our aim was to develop initial structures similar to the real structures of unalloyed steels that could later be used for simulating austenitization. Both simple models and models that can be compared to the real structures were developed. In our paper, it is described how the initial structures were developed by usin…
