In order to observe the orientation distribution of grains throughout
the whole sample thickness, the longitudinal sections of the asymmetrically rolled samples were
prepared by careful grinding and polishing.
This FEM result indicates that asymmetrical rolling with a large number of rolling passes promotes the shear deformation, which reflects the evolution of strong shear textures in the sample rolled by four passes as shown in Fig. 2.
The FEM calculations indicate that asymmetrical rolling with a large number of rolling passes promotes the shear deformation, which results in the formation of shear textures.

The whole process is confirmed by the ways of observation in
front of furnace, while the mixed materials are completely fused, vitrification, and there is no scruff,
unfused sand grain, bubble, then the crucible is took out by proper way and moulding model is
poured.

Glass-ceramics have a number of useful applications such as building materials, cooking ceramics,
machinable ceramics, bio-ceramics, optical materials, etc.[2] Recently, the preparation of glass-
ceramics from various wastes such as slags [3], coal ash [4], incinerator ash [5], waste glass and
shell [6], phosphorous fertilizer and oil shale ash [7], etc has been investigated.
This may be related to the microstructure, which consists of a great number of fine Wo grains in this glass-ceramic.

X-ray analysis gave the good number of lattice parameter for Ni3Si, a =
0.3522nm, and has good agreement with index.
On the other hand, there is also possibility that the reaction will form a number of stable Ni3Si phases.
XRD analysis data of Ni plated SiC+Al powder prior to sintering V.B.V.Strong : Very broad very strong, Calculated for β-SiC, ao=0.4364 nm, Calculated for Ni, ao=0.3523 nm, Calculated for Al, ao=0.4051 nm The lines for this phase are extremely broad indicating very small grain size and/or considerable strain broadening.

The method has been implemented to a number of industrial digital radiography system [4,5].
A set of multiple radiographs for a number of angles of view, namely 0o, 30o, 45o, 60o and 90o were collected.

A number of countries have also carried out
international cooperation in this regard.
Fig.1 Rice straw forming process The Machanical Technology of Rice Straw's Granulation Under the developing of the thermoforming technology of biomass to today, the market has a number of different ways of forming granulation equipment, these devices have their own advantages, but the prevalence of high energy consumption, low productivity shortcomings.
In the process of granulation, the gap between the die and the roller is extremely important, if the gap is too large, it is easily to lead to skid in the mold roll and the output is low, maybe sometimes there is no grain; gap is too small, modular roller mechanical wear is serious that affect the use of life.

Commonly, rapid cooling and crystallization of the non-equilibrium effect make a serious dendritic segregation and inside stress during solidification, which induce the significant unevenness component at grain boundaries, and those will bring adverse effect to the subsequent thermal processing [9-10].
