In many cases, aluminum parts were integrated in composite structure as structural and heat-exchange purpose allowing a weight-reduction without losing mechanical properties [8].
Furthermore, composite materials such as fiberglass or aramidic fibers (plus epoxy resin), are able to guarantee good electromagnetic transparency without causing reduction in sensor’s performance [9,10,11].
As previously discussed, experimental data were elaborated taking into account the guidelines provided by MIL-HDBK-5J Notice 2 for the estimation of the allowable stress for calibration of FE model purpose.

This transition occurs in response to the changes of reduction of interfacial growth velocity to critical values due to recalescence effects [8].
Moreover, the growth of the Si particles is controlled, mainly, by volume diffusion mechanisms [4], which are associated with very slow cooling rates of ~1.5 K/s obtained during the solidification of the spray-deposit [11], and they are in good agreement with literature data [5, 12].
Conclusions Spray forming showed to be suitable to induce microstructural modifications in the morphology and reduction of size and amount of the intermetallic phases formed in the Al-9Si-3Cu alloy.

In particular it will be shown that the important parameters are the size, density and spatial locations of the Cube fragments for which only extensive EBSD orientation mapping can provide relevant experimental data [6].
In a second experiment a sample of the same alloy was channel-die compressed at room temperature up to a strain of 2.3 (90% thickness reduction).
Moreover, by detailed EBSD experiments it is shown that during cold rolling to large reductions (90%) small micron-sized Cube fragments survive the rolling process, and are often located at the grain boundaries.

Therefore, the energy conservation and exhaust reduction in the wood drying process is a quite important task.
Therefore, the task of energy conservation and emission reduction is very onerous.The research and promotion using solar drying wood has been launched in many countries in the world, but more research is conducted in developed countries such as the United States, Britain, France, Germany and Japan and so on.
According to incomplete statistical data, the total drying capacity of solar drying wood accounts for approximately 0.2% [5].

High strength aluminium alloys (2xxx- and 7xxx-series alloys) that are usually employed in the aeronautic industry are normally difficult to fusion weld since dendritic structure is formed in the fusion zone when TIG and laser welding are used leading to a drastic reduction of the mechanical behaviour [4].
Successful application of FSW would allow for new structural and design possibilities as well as to contribute to weight reduction thereby increasing the efficiency and reducing the cost of production.
The Advanced MTS application software and the TestStarTM controller enable continuous data acquisition and management of key FSW process parameters.

Effects of Ru on the stress rupture properties of alloys Table.3 showed the data of stress rupture properties under the condition of 1070°C and 137MPa of Alloy 1 and Alloy 2.
The elongation and area reduction of Alloy 2 is also higher than Alloy 1.

Concerning the axisymmetric forward extrusion, the main process parameters that influence the product quality are: the area reduction factor (Ar), the die cone angle (αd), the frictional conditions at the die material interface, the material parameters (hardening, ductility, …) and the working temperature.
Re is the initial radius of the billet, Rs is the final radius of the billet after extrusion; L the initial length of the billet, α is the cone semiangle of the die and Ar=(Re-Rs)/Re) is the radius reduction factor.
Numerical results given by the proposed model seems accurate when compared to some available experimental data.

Compared with other waste disposal technologies, thermal treatment has several advantages: (1) Volume reduction; ( 2) Economic: could get gas and fuel oil of high heating value ; (3) The harmless and beneficial treatment efficiency is high.
However, available data indicated that the dioxins concentration in the flue gas increasing with the carbon monoxide concentration, so the oxygen supplication during this part of treatment is a key factor for the formation of dioxins
Children may behavioural disturbances, learning and concentration difficulties when affected by Pb, and people who have been exposed to lead for a long time may suffer from memory deterioration, reaction time lag and understand ability reduction.

The sample frequency was selected 100Hz, and time duration is 30s, and the average of data was taken as the three-component coefficient.
Once the attack angles exceed stall angle, the separation of flow will lead out in a large scale, and the vortex layer will break away significantly to transfer the vorticity to the main flow field causing to the reduction of lift coefficient and the appearance of curve acmes as well.
Once the attack angle exceeds the stall angle, the flow will arise to a large scale separation as soon as it touches the deck, and generates prominent vortex in the back segment of bridge deck, leading to the increment of drag force and the reduction of lift force.

The concept of a characteristic deformation temperature [13, 14] and the analysis of experimental data on the temperature dependence of mechanical properties of covalent crystals gave the basis for the authors to propose a generalized scheme for the temperature dependence of mechanical properties [13-16].
It was assumed [9, 18] that the sharp increase in strength when heated to temperatures close to Tdb is due to the reduction of the influence of stress concentrators (i.e. microcracks) due to stress relaxation near the crack-tips caused by the blunting of the crack-tips due to local plastic deformation during loading.
Polycrystalline silicon samples were synthesized by hydrogenous reduction of SiHCl3 on silicon substrates at temperatures 1000 – 1100 °C.
