A number of urban rail transit lines built and put into use in succession [1].
Use the rubber roller to compacting the carbon fiber in the fiber direction steadily, making the resin overflow from both sides, ensuring close-grained without hole.

When the hydrogen content of the workpieces is low, the microstructure of the workpieces has phase transition and grain refinement with the increase of amount of hydrogen, which leads to the improvement of the mechanical properties of the material and gradual decrease of its hardness.

An excitation yoke is made of two sheets of grain-oriented (GO) steel, each 0.35-mm-thick.
Its length is 1.90 m; diameter, 114 mm; and the number of windings (turns, N), 3533.

Introduction Equal channel angular pressing (ECAP) is an effective route to refining coarse-grain size into submicrometer or nanometer regime by means of large plastic shear deformation, which was first introduced by Segal [1].
The most advantage of ECAP is that the billet undergoes severe plastic deformation (SPD) but remains the same cross-sectional geometry so that it is possible to repeat the pressings for a number of passes in order to achieve a very high total strain.

Powder morphology and grain size were directly imaged using scanning electron microscopy (SEM).
These could be matched with JCPDS file number 06-0452 [11].

A number of alloying elements have been added to Mg-Al alloys to gain better high temperature mechanical properties, however most of them show some drawbacks such as low castability and high cost [1].
SEM-EDS investigations showed that some RE-containing phases were formed adjacent to Mg17Al12 phase at grain boundaries, but Sb-containing phases could not be easily found.

The coffinite of the exposed in the main quartz grain voids, uranium thorium along the pyrite, white iron ore on the edge of the distribution,and isomorphous uranium mainly paragenesis with Ce .

This phenomenon can be explained by the fact that the number of the sputtered ZnO molecules at the target surface increases due to the enhancement of bombardment by argon ions as the RF power increased [15].
The crystallite sizes were estimated using the Scherer’s formula which is given by [17]: (Scherrer formula) (1) where D is the crystal size or mean grain size, l is the X-ray wavelength, q is the Diffraction angle, and B is the Full Width at Half Maximum (FWHM).

Because metallic glass has no grain boundaries and there is a specific slip plane in the crystalline alloy, metallic glass has excellent mechanical properties not found in conventional crystal metals [1-3], including high strength, low Young's modulus, high corrosion resistance and high magnetic resistance.
The results are shown in Figs. 7-9 (circles mean mother number is 40-50, error bars indicate standard deviation).

Improved glass-forming ability (GFA) is thereby a possible consequence of the enhanced stability of ISRO, and a large number of Zr-based bulk metallic glasses (BMGs) with large GFA have been obtained accordingly [3].
Fig. 3 (a) shows the nanometer scaled microstructure with the grain size of about 50 nm.
