Continuous cooling transformation rules of Low Carbon-Manganese Steel were investigated on Gleeble-3500 thermomechanical simulator. The study indicates that as cooling rate increases, Ar3 loweres and Ar1 behaves similarly but much slowly. The microstructure composes of dominant ferrite and some pearlite. As cooling ra…
MMCs (Metal Matrix Composite) are very useful in the different branch of application like aerospace, automobile engineering and defense application. Of late surface modification of variety of materials is gaining importance. Various surface modification techniques are being used some at research scale and some at indu…
Intergranular Stress Corrosion Cracking (IGSCC) of austenitic Stainless Steels (SS) in Boiling Water Reactor (BWR) environment is generic in nature in both the sensitised and the non-sensitized conditions. IGSCC in non-sensitized austenitic SS in the strain hardened condition has been reported without any grain bounda…
GaAs nanopillars show promise for energy applications. Understanding, characterizing and modifying the structure of the pillars will be very important for optimizing the properties of the assemblies. EBSD was used to investigate the orientations of these nanometer structures.
This paper describes nucleation and grain coarsening at very early stages of recrystallization in AA3104 aluminum alloy containing complex structure of second phase particles. Measurements of individual sub-cell orientations in ECAP-processed and slightly annealed structures were possible by using TEM-based orientatio…
The heat-press bonding technology of water proof and breathable fabrics with thermoplastic adhesives will play an important role in the processing of stitchless apparels, they will influence not only the stiffness and the processability, but also influence the function and the quality of stitchless apparels. This stud…
One-pass hot rolling in the ferrite region was conducted at higher temperatures, using various rolling temperatures and rolling reductions, with two types of ULC steels, 0.016% Nb and 0.023% Ti, and recrystallization behaviors immediately after hot rolling were investigated. The γ-fiber strength reached its maximum at…
This research presents a novel process for dry wood parts carbonization to net shape porous carbon body which retains all the wood’s anatomical feature. Due to reasonable price, easy shaping and good formability of wood, as a raw material, it can be used in several advanced cellulose-based applications without any spe…
The performances of Ce-doped Lu3Al5O12 (LuAG:Ce) and LaBr3 (LaBr3:Ce) scintillators were compared for γ-ray detection using photomultiplier tube ( XP5500B PMT) readout. For 662 keV γ-rays (137Cs source), an energy resolution of 3.5% obtained for LaBr3:Ce is much better than that of 6.7% obtained for LuAG:Ce, while the…
X-ray diffraction line profile analysis can be carried out on the hkl planes corresponding to the same texture component or the same crystallographic orientation fiber. It is shown that in textured polycrystalline materials or in thin films or multilayers X-ray line profiles measured on planes corresponding either to…
The changes in crystallographic texture are investigated during recrystallization in 5182 and 6016 aluminum alloys, which were subjected to various cold rolling reductions. In the current study, the texture varieties in the recrystallized materials are conditioned by both the material’s chemistry and the applied rolli…
Non-oriented grain type electrical steels are used mainly in electrical rotating machines such as motors and compressors, in which the magnetization direction rotates 360 ° every cycle while remaining in the plane of the plate. The performance of these devices is affected by crystallographic texture of electrical stee…
A new electron-rich unit, 2,7-di(5-bromothiophen-2-yl)-10-hexadecyl- phenoxa-zine, has been prepared in high yield over four steps. The compound with good solubility, electronic and optical properties may be a candidate for D-A type organic polymers.
In silicon steels, interaction of grain boundaries with particles occurs in a selective way. Currently, it is very difficult to include this preferential interaction directly in the classical simulation models. A new approach of grain growth simulation based on the concept of curvature-driven migration of the grain bo…
Nanomaterials include nanometal, nanooxide, carbon nanotube, carbon nanotube composite and other types of nanomaterials. They provide a significant way for the manufacture of sensors due to their small size, larger specific surface area, surface atomic slots insufficiency and more active sites. The rapid development o…
The Ti/TiC/C laminated composite material was fabricated with the sheet of Ti and C by spark plasma sintering (SPS) technology. The effects of thickness ratio on the interface characteristics and mechanical properties of interfacial reaction were studied. The results show that: the reaction layer thickness increases w…
The dissolution of silicon into germanium melts has been investigated for application to solution crystal growth. Small diameter samples were processed to weaken flow structure in the melt making the transport mechanism diffusion dominated. 8mm diameter samples were processed at three different temperatures. The tempe…
This paper analyzed the basic physical and chemical characteristics of methanol diesel blended fuel. The power and fuel economy performances were studied experimentally when methanol diesel blended fuel was supplied to JiChai 3012 diesel engine, without any changing of the configuration of this machine.
