During the hot spinning process, the crystal grains are displaced along the sliding surface of the deformation zone under the action of the three-directional deformation force.
The upper rim showed more features of dimples while there appear a large number of cleavage platforms in the spoke.

The grain size estimated for TiH2-X from the Scherrer formula [9] was 5 - 9 nm.
The number of peaks in the TPD spectrum, corresponding desorption temperatures and the amount of desorbed hydrogen provides information on the state of hydrogen in material.

Number 20 engine oil was used as lubricant.
Although high sintering temperature and long sintering time can reduce pore concentration, they were not preferred not only because of the higher cost but also it may cause part deformation and grain coarsening.

It is believed that DPBs are highly uncoherent grain-boundaries and the high energy stored is (in part) relaxed by the high density of MTs.
They are Multiple Bound Exciton Complexes (MBEC) which have been labelled m=2 to 5 to indicate the number of electrons and holes which participate in the final (excitonic) molecule.

The relationship between hydrogen and poly silicon have been well studied in fin-type double-gate MOSFETs (FinFETs) process [10], in which hydrogen annealing technique is used for getting FinFETs with higher mobility by improving roughness of poly grain due to high surface migration rate.

Grain boundaries present in polycrystalline films are thought to be paths for leakage current as well as sites for defect proliferation during high-temperature processing [4].
At lower temperatures, the film remains amorphous for a larger number of ALD cycles compared to at higher temperatures.

.% on the metastable phases formation, grain size and hardness evolution during MA process.
The powders were initially blended to the desired compositions of Ti-52.7Al-5V, Ti-55.4Al-10V, Ti57.7Al-15V and Ti-60.4Al-20V (numbers indicate at. %) under the argon atmosphere in the glovebox equipment.

Number of studies conducted on commercial aluminum-based composite systems revealed a decreased in ductility with an increase in crack initiation (stress accumulation) sites, such as the amount of TiB2 particulates[19,20].
microstructure showed grains of Al particles surrounded by TiB2 particles, as shown in Figs. 2(a,c,e) but at the center of compact as seen in Figs. 2(b, d, f) a region showed a uniformly distributed TiB2 in the aluminum matrix.

Table 1 The characteristic of pulp KMnO4 numbers Yield[%] Brightness[%ISO] α-cellulose[%] Original pulp 8.7 81.9 - - Bleached pulp 3.3 - 86.6 92.5 MCC Preparation.
As shown in Fig. 1b, 1c and Fig. 2b, 2c, the yield and grain size were declined with the prolong time, so to shorten the hydrolysis time can increase the yield when the ratio and temperature were fixed.

Using TWBs a strong reduction of the number of the parts can be reached by an optimized distribution of the material’s mechanical characteristics in the final stamped part together with the desired weight distribution and thus a significant reduction of the components mass can be realized.
Heat mainly affects material flow, grain structure and therefore the tensile strength in the weld zone which leads to reduced components strength [3, 4].
