The atomic configuration in the parent and martensite phases of Cu-Zn-Al alloys and in the parent, martensite and bainite phases of Cu-An-Zn alloys have been examined by the atom location by channelling enhanced microanalysis (ALCHEMI) method, although th

The isothermal crystallization behavior of amorphous Fe(77.5)Si(13.5)B9, Fe(74.5)Si(13.5)B9Nb3, Fe(76.5)Si(13.5)B9Cu1 and Fe(73.5)Si(13.5)B9Cu1Nb3 (at.-%), have been investigated by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Duri

ACRT (Accelerated Crucible Rotation Technique) is a newly developed functional crystal growth technique and has been successfully employed to grow some functional crystals of superior quality, such as antiferromagnetic semiconductor MuTe, IR crystal CMT,

Aluminum-Lithium alloys is of considerate interest to the aerospace community due to their high strengths and stiffness. Basic research in the Al-Li based systems was stimulated once more since the icosadral quasicrystal T2-A16Cu3Li was observed in the Al

In this research, welding joints of steel 16Mn in the same state of initial microstructure and residual stress were subjected to shock wave with different intensity by changing the distance between explosive and the sampling location of the specimen. The

Compositional analysis using the atom prober suggects that it is necessary to invent new parameters to describe some aspects of microstructures. Experimental and calculation work indicates that fractal dimension can be used to describe structural aspects

The fracture detlections and fractal dimensions of fractured surfaces of the composite coatings containing multiphases were determined. The fracture characterization of the composite coatings was analysed and studied. The test results showed that the frac

Nanocrystalline ZnFe2O4 have been prepared by the PEG gel method and their structure and magnetic properties were examined by the X-ray diffraction, transmission electron microscopy. It was shown that prepared samples have a single-sprinel structure and a

The three dimensional FEM program and the unit automatic dividing program are developed fitted the continuely rising temperature field. The changed results of inner temperature field with surface temperature field are calculated in two different bodies in

The microwave sintering process of the ceramic composite made of ZrO2 and Al2O3 have been studied. The microstructure of ZTA (ZrO2 toughing Al2O3) ceramic are analyzed by means of XRD and SEM. The bending strength and relative density of ZTA are measured.

Ta2O5 used in double-layer gate insulator a-Si TFT is formed by anodizing Ta. its process is compatible with fabricating process of TFT and its performance is excellent. We use citric acid solution as electrolyte and constant-current source as the power.

LaCrO3 nanometer powder having different particle sizes was prepared by pyrolysis of amorphous citrate. XRD indicates the LaCrO3 synthesized was single phase and orthorhombic in structure. The mean particle size of LaCrO3 moreses greatly with the increase

α-Fe2O3 and SnO2 doped α-Fe2O3 were made by chemical precipitation and hydrolysis. Effects of doping methods on microstructure of α-Fe2O3 were studied with XRD and TEM. Effects of doping methods on gas sensitivity and resistance of α-Fe2O3 were tested wit

The design of thermosetting resins for optimizing storage stability and cure schedule is an important consideration in application. It is apparent that the reaction with relatively large Ea and A values (in Arrhenius equation) is most desirable for this g

The fatigue crack propagation threshold and the crack deflection angle under (Ⅰ+Ⅱ)mixed-mode loading were studied in a hot-extruding 19 vol.-%-SiCw / 6061Al composite. Microstructure and fractogfaphy of the composites were observed by SEM. The fatigue cra
