The plastic deformation of submicrocrystalline titanium is considered. By speckle photography and X-ray diffraction analysis, the distribution of local deformation and elastic stress in the working section of the samples is studied. At the prefailure stage, a site of localized deformation is formed, with maximum compo…
CRT- 83 carpet rapier loom is a kind of high-grade rigid rapier loom，the weft yarn will give looms to demand higher stability of the weft insertion. Theoretical analysis based on the theory research of the stability of clamping weft and weft handover shows that the rapier deformation，slipping force and the depth of cl…
(Pr0.5Nd0.5)0.7Ca0.3Cr1-xCuxO3–δ(PNCCCx x=0, 0.5, 0.1, 0.15，0.2 ) interconnect material and electrolyte powders of Sm0.2Ce0.8O1.9 (SDC) were synthesized by citric acid nitrates self-propagating combustion methodThe phase and microstructure of the sintering samples were investigated by X-ray diffraction and scanning el…
Superior electrical properties of carbon nanotubes were utilized by the authors in the fabrication of printed resistors. In common applications such as electrodes or sensors, only basic electrical and mechanical properties are investigated, leaving aside other key parameters related to the stability and reliability of…
An unsymmetrical diarylethene derivative bearing both phenyl and thiophene moieties, in which a cyano group was substituted at the ortho-position of the phenyl ring and a chlorine elements was substituted at the five-position of the thiophene ring, was synthesized. At the same time, its photochromic properties and flu…
The rare earth-cobalt compounds with CaCu5-type structure were discovered to have outstanding permanent magnetic properties. The thermal stability of Y1-xErxCo5(x = 0, 0.12, 0.24) was investigated by X-ray powder diffraction, differential thermal analysis and scanning electron microscopy with energy dispersive analysi…
The decision-making and control system of a burner-type diesel particulate filter (DPF) regeneration was designed. Through the online simulation and the application research, it showed that the regeneration system had good response performances on prediction, decision-making, support and control. The DPF regeneration…
A novel unsymmetrical photochromic diarylethene, 1-(2-methyl-5-chlor-ine-3-thienyl)-2-(2-ethyl-benzofuran-3-yl) perfluorocyclopentene (1a), was synthesized and its photochromism and photo-induced anisotropy was investigated. Specifically, photochromism in solution and in PMMA amorphous films were studied. The diarylet…
In this paper, high resolution electron microscopy (HREM) was used to observe nanosized Fe2M precipitates in M50NiL steel, and crystal structure of which was also investigated by selected area electron diffraction (SAED). At the same time, the orientation relationship between the Fe2M and the martensite matrix was als…
In this paper, the higher-order elasticity constants are evaluated in the theoretical scheme of higher-order continuum. A single-walled carbon nanotube is treated as a higher-order continuum cylindrical tube with a thin wall, and the representative cell is chosen as a triangle unit that contains four carbon atoms. The…
Recently titanium and nickel alloys have become eminent for making aeronautic and astronautic parts. Since both titanium and nickel alloys have very low thermal conductivity, the tool will be suffered from a huge damage by the generated heat during machining process. It is required for a durable tool with excellent co…
As the rapid growth of integration level in the power electronic devices, the high dissipation power and low withstand voltage greatly affect the reliability of Integrated Power Module (IPM). Therefore, it is essential to study the performance of the devices or their substrates at the elevated temperatures. In the pre…
Ni-P ultra-black films were prepared by ultrasonic chemical etching of electroless plated Ni-P films using 8 mol/L nitric acid at 40 °C for 20 s with different ultrasonic power ranging from 0 to 195 W. Scanning electron microscopy (SEM) was used to study topographic characteristics of the films. The results show that…
