The number of withdrawn of natural minerals very often are so great that it leads to a violation of the natural landscape, changing of wild animals migration routes, habitats of flora distortion and a shift in the ecological balance of natural ecosystems as a whole.
Tests pigments - fillers offered by us (sample number 1 and 2) were investigated in the conditions of a production laboratory of "Quil paint factory", Belgorod, according to the following parameters: dispersibility, milling degree, relative viscosity, hardness, drying time, adhesion and elasticity.
Grain size, phase and oxide compounds of these wastes are presented in Fig.4, Table 2, 3.

Basic classification for resin bond in abrasive products Resins for fixed abrasive products are mainly phenolic resin, polyimide, epoxy resin, polysulfone resin, etc. (1) phenolic resin includes ordinary phenolic resin (such as number 2123, etc), modified phenolic resin (such as boron phenolic resin, new phenol resin, etc) to meet special requirements; (2) polyimide resin has high temperature strength, corrosion resistance, wear resistance better than phenolic resin, but it is expensive; (3) epoxy resin.
It is usually as bond to manufacture fine-grained polishing wheel and other special abrasive tool[8].
However phenolic resin has its own limitations, the domestic and foreign scholars develops a number of modified phenolic resin research.

A large number of inorganic filler not only will lead to the decrease of mechanical properties but also significantly increase the viscosity of polymers, resulting in the deterioration of processing performance and products[1-2].
When the concentration of tetra-isopropyl titanate is lower than 1%, the FT-IR dates show that the grain can not cover the surface of inorganic particles fully, but the amount of tetra-isopropyl titanate grafted onto the surface of inorganic particles increases by increasing its concentration.
On the contrary, the surface of GGBFS links with a large number of tetra-isopropyl titanate molecules after activation by the latter.

Part geometry and mechanical quality The whole point of thixoforging is to make complex-shaped parts while reducing the number of forming steps (sometimes down to one single step) to obtain a Near-Netshape part [10-12].
It is certainly superior to that of parts obtained by molding because of the grain flow and refinement, while allowing just as complex shapes.
The industrial setup installed to thixoforge the C38 part (figure 4) has shown it is possible to produce a large number of parts with die speeds and wear compatible with economic and industrial constraints.

Brittleness and grain interface fracture of high Cr and Cr-Mo cast steels can be controlled by moderate contents of aluminum and nitrogen elements plus sustaining temperature out of 900~1200℃ range[6].
By the code ASTM E813-89, an effective measurement must meet the requirements of fracture surface crack morphology, i.e. numbered nine lines representing the crack lengths ai (i=1, 2, …, 9) should be measured with a same interval distance along the crack tip.
The fracture roughness, KIC,P-C, at arbitrary P-C levels can be evaluated using formula ( ) ( )[ ]( )rmsIc s1 avIc lg1 lg IC, 10 KntZK CP CP K −+− − − = (3) where lgKIC,av and lgKIC, rms are average value and standard deviation of the test logarithms of fracture roughness KICi data; i=1, 2, …, ns; ns is number of the KIC data.

As a part of controllable solid propulsion (CSP) technology, Aerojet had developed the ability to control multiple variable thrust pintle nozzles integrated on a single gas generator with a solid propellant grain [14].
The frequency and number of the pulses to be received are directly related to the velocity and the final position of the pintle, which determined the valve opening (Fig. 2(c)).
The thrust coefficient (CF) changes a little during the pintle movement, and is regarded as a constant number in this paper

In addintion, in a large number of hydraulic fracturing problems there is a strong interdependence between deformation (stress) and fluid flow and standard modeling of these various processes as separate and non-interdependent can lead to significant errors in many cases [6].
As we well known, rock is a very heterogeneous geological material, containing many natural weaknesses, such as pores, grain boundaries, and pre-existing cracks.
The number of failed elements and associated energy release proportional to acoustic emission (AE) accompanying hydraulic fracturing are also numerically recorded [11], which will be plotted along with the borehole pressure.

It is also stated that with increasing processing time, the oxide layer grows in its thickness but the spark discharges becomes few in number and coarse in size [46].
Marginal refinement of grain size was noticed in the case of current pulsing.
At the initial stages of arcing, a large number of fine arcs wandering on the surface are formed.

However, the polycrystalline brittleness and thermal stability resulted from large grain size and the segregation of γ1 (Cu9Al4) are the main obstacles for the development of Cu-Al-based HTSMAs [1,2].
From Fig. 2, it is found that a large number of the copper-colored precipitate forms for the studied three samples.
Under the aged state, a large number of α(Cu) phase precipitate for three types alloys.

Powder production involving rapid solidification offers a number of unique advantages that are important to the ductility of the material.
For example, segregation in the powdered material can be minimized, very fine grains can be produced, and the solid solubility of alloying elements can be increased.
Recently, a number of synthesis and processing routes have been developed to produce high performance, cost effective and near-net shape sintered aluminum components, solely by the PM route [2-3].
