The similarity regularities of thermal-mechanical effects are analyzed and discussed by means of FEM numerical simulation method.
List all important parameters affecting structure thermal-mechanical response and their dimensions.
Thermal-mechanical effects in the region of thermoelasticity for models with different scale factor have been simulated by finite element method (FEM).
The change of thermophysical properties of material with temperature must be considered.
Secondly, the stress, induced by thermal effect, has been quantified by solving the thermal-mechanical governing equations.

This technique is combined with molecular dynamics techniques to study the role played by Fe impurities in the properties of nanocrystalline Cu grain boundary properties.
Properties of grain boundaries in polycrystalline materials are greatly affected by the presence of impurities that segregate to them or, for concentrated alloys, by the local composition.
An adequate choice of solute elements can also control mechanical properties through changes in grain boundary dislocation nucleation behavior.
Impurities or solutes may play a beneficial role in nanophase materials by affecting three different properties, namely hardness, stability and cohesion.

In addition to the above factors, the intensity of bio-damage processes also depends on the intensity of the photochemical effect, on aerobic or anaerobic conditions, on all the factors affecting the mass, kind, type and intensity of microorganism’s activity, therefore the mechanism of bio-damage is more complex and multifaceted than the corrosion process caused by chemically aggressive environments.
The great interest in polymer-impregnated concrete is explained by the fact that as a result of special processing of concrete with polymers, the strength of the material increases several times, its resistance dramatically increases when exposed to a number of aggressive environment and influenced by other factors as well as polymer-impregnated concrete can obtain special properties unattainable for ordinary concrete.
The properties of the final concrete polymer depend on how deeply and completely concrete is impregnated.
Along with using full impregnation in order concrete has high strength or special properties we can use surface impregnation to a certain depth to increase the material’s longevity and stabilize the properties obtained in time.

Recent research in the process of die casting production of aluminium alloys which are nowadays deeply implemented in the rapidly developing automobile, shipping and airline industry aims to increase the manufacture and quality properties of the casting in order to obtain its high mechanical properties at acceptable economic costs.
Another important parameter of casting is the quality of the casting alloy after refining which also affects the final quality of the casting.
The structure of foundry alloys is a determining factor of the casting properties and in terms of operational reliability a factor limiting the distribution of foundry defects in the casting. important parameter is the quality of the casting alloy after refining and its temperature which also affects the final quality of the casting.
Based on the experimental analysis of internal defects of die castings it can be concluded that among the most common internal defects affecting the quality properties of the casting include cavities with oxidized surface membrane of oxide Al2O3 situated on the interdendritic space that are classified in the category of exogenous bubbles and Al2O3 particles often in combination with internal cold laps.

Introduction Triple junctions (TJs) are now becoming recognized as one of the most important and essential elements affecting texture evolution and mechanical behavior.
To a reduced extent, both grain boundaries [7] and precipitates [8] can also serve as nucleation sites because of their suitable geometric, physical and crystallographic properties.
The grain boundary character distribution is an important feature of the texture and affects many of the material properties.
In this regard, variant selection was somewhat stronger on planes with high Schmid factors, in the order primary, secondary, and so on, irrespective of the strain.
The observed tendency in Fig. 5 for the twinning plane fraction to be higher on planes with higher Schmid factors may be associated instead with the ease of folding and of the formation of triple junction affected zones (TJAZs).

This result suggests that other electronic or structure factors can influence on metal-hydrogen interaction and structural stability of transition metal hydrides.
The obtained results have shown that both magnetism and structural defects can play a key role in hydrogen sorption properties of palladium based alloys and can strongly affect the hydrogen-metal interaction.
The magnetic properties of alloys were studied in the framework of spin-polarized calculations.
The cell volume relaxations have been also applied, since the formation of metal-hydrogen-vacancy defect complex induced a large lattice strain, which can affect the electronic and structural properties of the alloys [2].
Our preliminary results have shown also that magnetism can strongly affect the metal-hydrogen interaction and the binding properties of hydrogen induced defect complexes. 4.

The influence of cutting conditions on friction and wear properties of PEEK, CF/PEEK and GF/PEEK composites using PCD tools Wenxia Wang School of Mechanical and Electronic Engineering, Shanghai Second Polytechnic University, Shanghai 201209, P.R.
The investigation illustrates that the addition of reinforcements to PEEK improve the tribological properties relation with the cutting conditions.
Introduction The use of newmaterials in technology development permitted that materials such as polymers find a new and quite relevant role in tribological applications (friction and wear) in which the service temperature, the environment with significant moisture, the high stiffness associated with the low density and chemical resistance appear as decisive factors in the selection of the material.
It has been reported that the reinforcing PEEK with some fibres has a beneficial effect on its strength and tribological properties[4].
Moreover, the successful performance of machining operation is significantly affected by the properties of work material[7,8].

Their effects were investigated in terms of the microstructure, using positron annihilation lifetime techniques and mechanical properties monitoring via Vickers hardness measurements.
Its strength is affected by the presence of Mg2Si in various forms.
These characteristics, as is well known, largely determine the mechanical, electrical and magnetic properties of metals [2, 3, 5, and 7].
The changes in mechanical properties were measured using the Vickers hardness method; the standard method for measuring the hardness of metals, particularly those with extremely hard surfaces. 3.
