Gregorio del Amo 8, 28040 Madrid, Spain Keywords: Magnesium alloys; mechanical properties; LPSO-phase, microstructure; superplasticity Abstract.
Most of the research in magnesium alloys reinforced by LPSO-phases has been focused in determining the structure of LPSO-phases [1,2], the influence of LPSO-phase orientation/texture on their mechanical properties [3] and/or elucidating the deformation mechanisms at low temperatures [4,5]: Nevertheless, less attention has been paid to their mechanical behaviour at high temperatures.
The microstructure of all alloys was characterized by scanning electron microscopy (SEM), while the identification of the phases was performed by X-ray diffraction measurements (XRD) Tensile mechanical properties were evaluated in the temperature range 300-350°C.
The coarse size of LPSO-phase particles can constitute a limiting factor during plastic deformation, as deduced from the lower elongation attained by the Mg95.5Y3Zn1.5 alloy, around 140 %.

Severe plastic deformation produces a broad spectrum of high-angle grain boundaries (GBs) with different kinetic properties.
The resulting hierarchy of internal interfaces turned out to affect strongly the kinetic properties of the nanostructured material.
Severe plastic deformation The severe plastic deformation (SPD) processes have been studied extensively due to their potential to produce full density fine grained structures with attractive and rather unusual mechanical properties [3, 30].
The kinetic properties of SPD materials would strongly be affected by these 'non-equilibrium' GBs.
The SMAT enhances mechanical and tribological properties of the surface layer in different materials.

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.

They have a wide temperature range, high chemical resistance against corrosive media, while having higher thermal protection properties.
The purpose of this research is also to study the features of the physical and technical properties of basalt fibers when changing modes of pre-mechanical and thermal treatment when using them as a reinforcing component.
These features sharply change the physical and technical properties of the fibers, which affects the basic characteristics of the materials made on their basis.
Building materials and products for the exterior insulation of the walls of residential buildings using ventilated facades must have appropriate thermophysical and physical-mechanical properties.
The insulation used in the structures of the exterior insulation of the walls of buildings is subjected to such operational factors as the alternating temperature and humidity regime; capillary and diffusion moisture; the effects of wind loads, self-weight mechanical loading, and so on.

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.

Unfortunately, assumptions have been made in these works that properties of the devices are all deterministic.
The uncertainties are mainly caused by variations in materials properties, like Young’s modulus, geometrical features, like dimensions and gaps, operating environment and boundary conditions.
With the initial design point, we consider the key geometric factors.
When beam width is larger than 9μm, the device area is severely affected.
In the future work, we would like to focus on variations of material properties and performance under multi-physics, like coupled mechanical-electrical questions.

Many processes and their relative factors are optimized using statistical techniques such as Taguchi method, Response Surface method (RSM), Grey Relational approach (GRA)etc.
The authors identified tool traverse speed as a significant factor that affects hardness and bending characteristics of FS welded specimens.
The above studies help us in identifying the significant parameters in FS welding process that can affect the mechanical properties such as tensile strength and tensile elongation.
The mechanical clamps were used to clamp the plate in the worktable of the machine.
The range and respective units of each input and output factor differ.

Some researches studied the influence of chemical degradation effects on mechanical properties: flexural and compressive strength of polymer mortars.
It is difficult to obtain high molecular weight orthophtalic polyester and for this reason, the chemical and mechanical properties of this material are inferior to those of isophtalic polyester.
We intended to detect whether it has some influence or not on other properties of the material such as its behavior under fire [21].
