Due to which the SZ is the main key region for this study, thus the BM has been trimmed to concise size without affecting the thermo-mechanical model.
To improve mechanical properties, it is crucial to choose the ideal TRS. 3.2.
It should be highlighted that grain size, temperature and plastic strain are the only factors used to differentiate these four zones.

From the beginning of 2009 April, the State Administration of production safety supervision and management institutions directly under North China Institute of Science and Technology -- from what Dr invented the deep processing of solid waste artificial jade Technology Based on [1-4], the artificial jade appearance and intrinsic properties and natural jade close, can be used in the production process of goods and high-grade building materials and other products, to achieve the waste and low value of minerals high value added utilization, significant economic and social benefits, and do not have two times of waste, and has wide application prospect and popularization value, has a broad application prospect in the industry of coal, metal and nonmetal mines, metallurgy, power plant, etc..
There are a variety of molding process of artificial jade products, such as lost wax casting, molding method, mechanical method, they each have their own characteristics, which are suitable for different characteristics of the products.
The main factors affecting the molding temperature, pressure and time, and the liquidity and material temperature, pressure, flow of purple jade can through the composition optimization to control, in order to meet the requirements of molding.
There are many kinds of press, by mode of transmission is mechanical and hydraulic presses, the most common form of mechanical press with a spiral type presses, crank lever type etc..
Because the mechanical press pressure is not accurate, the movement noise is large, easy to wear, especially hand press driven by manpower, the labor intensity greatly, so rarely used mechanical press factory.

Abstract.
Although low ductility and poor formability properties always accompany Mg alloy at room temperature due to the hexagonal closed-packed crystal structure, the development of some effective forming techniques overcoming this forming difficulty for this kind of material is strongly worth exploring in industry.
The investigated factors are type of lubricant, initial extrusion speed, temperatures and type of material.
ANOVA was used to investigate how parameters affect the extrusion process.
The shear friction factor, m, specified at the interface between tube billet and the forming tools varying from 0.01 to 0.3.

Introduction
At the core of any solid materials processing technology is a series of specific chemical or physical processes affecting on the processing object.
The development of combined methods of parts processing (CPM) implies the union or combination of several inhomogeneous processes, allowing to obtain a part with improved properties [1].
The CFE planning matrix of this type has the following properties: symmetry, normalization, orthogonally, and ratability for a linear model.
For the eight solutions given above, replicas 1…6 include three factors, and replicas 7 and 8 four factors each.

This paper reviews the results of gallium (Ga) additions on the properties of Lead (Pb)-free solder alloys in terms of the solderability, microstructure and mechanical properties.
The formation of Cu6Sn5 intermetallics would be beneficial for solder joints in terms of mechanical properties as the fine structure of intermetallic particles in bulk solder could reinforce the solder materials and enhanced their mechanical properties [10,16-17].
Then, with the content of Ga is 0.1 wt.%, the size of primary rod like Zn-rich phase become smaller and will slightly improved the mechanical properties of solder materials.
It is proved with the proper addition of Ga it will slightly improve the mechanical properties by turning the primary rod of Zn-rich smaller.
Hence the mechanical properties of the Pb-free solder are able to attain the best in this component as well [22].

To a large extent, the design and the property quality of belt ply and carcass will directly affect the quality of radial tire. while moving , the belt ply is the main stress components, and its main component is the steel cords.
Rubber is an isotropic and incompressible elastic body, its physical properties showed a high degree of nonlinear, therefore, steel cords can be considered as linear elastic material[2].
During the operation of the tire, steel wire in belt ply is the main stress components,the property quality of the tire is mainly reflected in the strength of steel wires and the adhesion properties among steel wire.
From the above equations we can see that the tension of steel wire is not only related to its own property but also the shape of tire, the angle of steel wire placed and the size of outside loads.
However, while in the process of driving, the tire is affected by the road conditions, temperature, pressure, etc, and many other factors, so simulation results obtaining from the analysis in this paper may have a certain deviation from the actual situation.
