Introduction The development of components and parts with high functionality frequently envolves the selection of options where materials with different mechanical properties are combined.
Depending on the mechanical properties of the material, a pile-up (Fig. 1a) or sinkin (Fig. 1b) morphology may be observed [6,15,16].
The elastic and thermal properties of the aluminum (elastic modulus E= 68.9 GPa, Poisson ratio ν=0.33 and coefficient of thermal expansion α=23.6 x 10-6 K -1) were taken from the literature [9].
Fig. 4b, 4d and 4f also allow observing that the load is an important factor regarding the diameter of the cavity generated during the indentation.
In this case, one factor that would be representative of that tendency is the plastic deformation of the substrate.

Due to a variety of factors, the rock-fall event generally has the law which is multiple, abruptness, randomness and so on.
The mechanism of slope rock-fall disaster [6-9] The sufficient condition of rock-fall events is loose rock (the sources of rock-fall) on slope, external factors (the factors to occur rock-fall) and the rock where the terrain slope is greater than original angle of repose, then the rocks will move downward along slope because loss of balance.
Overall, the factors of rock-fall divided into internal and external factors.
The internal factors are mainly structure, physical and mechanical properties, degree of weathering, environment of ground stress, groundwater environment and so on.
And the external factors are mainly natural variation (precipitation, temperature, freezing and thawing, plant root hack, seismic activity, etc.), human activities of excavation, as well as other causes of the disturbance.

Domestic research starts late in diamond cutting tools, which constrains the development of diamond cutting tools in China, affects the market share and results in a big gap comparing with the world advanced level.
CVD diamond which is similar to natural diamond in properties can be used to make thin diamond film coated tools and brazing diamond film tools, which can be sued to machine auto parts. 2.2 Preparation technologies of diamond cutting tool materials The application of natural diamond cutting tools has a history of hundreds of years.
However, due to limited resource, higher manufacturing costs and other factors, natural diamond cannot fully meet current industry need, so a variety of synthetic diamond material emerges.
Synthetic diamond of large single crystal has the same excellent properties as natural diamond; we can achieve ultra-precision machining by using tools of this diamond material.
Nanometer diamond simultaneously has properties of nanometer materials and diamond materials, and as a tool coating material, it can improve efficiency and extend tool life.

It is known that dislocations, i.e., linear defects of the crystal lattice that violate the correct alternation of atomic planes, affect the processes of plastic deformation and fracture of materials under the influence of stresses.
However, dislocations affect not only the strength of solids, but also their electrical resistance, internal energy, optical, semiconductor, magnetic and other properties [1], determine the mosaic structure of real crystals, surface topography and the nature of crystal growth at small supersaturations.
Therefore, by tracking, through analysis of the characteristics of the propagation of elastic waves in a solid, the changes occurring with a dislocation microstructure, one can evaluate the mechanical properties of the material and also predict the residual life.
To create a model that takes into account the nonlinear elastic properties of the medium, it is necessary to analyze the behavior of the elastic fields of a dislocation near its axis, since this is a region with a high concentration of stresses.
Nonlinear Stationary Waves If the influence of dissipation on the evolution of wave processes in (6) is small BA→0, then, as a result of competition between dispersion and nonlinear factors, stationary waves can form in the system.

All this leads to appearance of defects (pores, cracks), which significantly impair the mechanical properties, and, consequently, reduces the reliability and durability.
Graphical dependences of the characteristics of the obtained joints on the most influential factors (parameters of technological modes) were obtained.

Some authors correlated the fatigue strength to the coating thickness of the zinc layer [1] while other authors did not support any specific correlation of loss in the fatigue properties due to the coating thickness [2,3].
Vogt et al. [4], by appropriately employing the Kitagawa–Takahashi diagram were able to identify a threshold value of the coating thickness not affecting the fatigue behavior of unnotched components made of structural steels.

Stress corrosion cracking (SCC) is one of the most important questions about affecting chemical and oil equipment.
Welding residual stress is one of the main factors causing SSCC and SOHIC[5].

That is because heating above the BTT at the finishing steps of heat- and thermomechanical- treatments leads to strong grain growth, followed by mechanical properties degradation.
Thus, there is a demand for a BTT determination technique based on physical properties measurement.
There are many factors affecting the experimental results of DSC investigations: the temperature regime of an experiment (heating/cooling rates, exposure time) and the controlled atmosphere in the DSC-cell during an experiment.
To perform an accurate determination of any critical points by means of the DSC method, the values of all the factors should be carefully analyzed and selected.
To limit the number of factors affecting the DSC results, all the chosen alloys were characterized by a value of aluminum equivalent from 8.5 to 10.5.

Several binary and ternary nitride systems, such as TiN, CrN, and TiAlN, have found industrial applications, owing to their good mechanical and thermal properties.
Many studies of CrN films in BMS processes have concentrated on their mechanical properties [9-16], but the grain structure, the crystallographic orientation and other properties of these coatings depend very much on the deposition technique and parameters.
The aim of this work is to determine the distribution of the varying magnetic field and its effect on mechanical properties.
