The characteristics of the medium in terms of its physical, mechanical and physicochemical properties may be of a wide range [1–3].
The latter, in addition to the force factors, is also determined by the boundary conditions.
for natural values of the material factors Steel Grade 45 takes the form:
Vibrational centrifugal processing of parts involves a complex combination of mechanical, physical, and chemical phenomena that significantly affect the condition of the surface layer, and surface defects influence the mechanical and physical properties of materials.
Similarly, but with a weaker influence on mechanical properties, the size of subgrains also plays a role.

Among the process parameters, electrolyte provides a leading role owing to its vital influence not only on the films’ chemistry but also on the electrical conductivity of the circuit, which affects the film properties.
Introduction Titanium (Ti) and its alloys have been extensively used as dental or orthopedic implants because of their excellent mechanical properties and biocompatibility.
Research demonstrates that process parameters such as electric potential, applied frequency, treatment time and electrolyte have decisive effects on the properties of ASD films[5-7].

Introduction Energy and environmental issues have always been hot and difficult in the economic development of the world, but also have become the main restricting factors of sustainable development.
Meanwhile, Mo and W are the important solid solution strengthening elements, which affect the mechanical properties of super alloys.
In this paper, the effects of Nb, Al, Ti, Mo and W elements on equilibrium and mechanical properties of the Ni-Cr-Co type Inconel 740H was analyzed to optimize the chemical composition of Inconel 740H alloy.
Fig. 6 Effect of W element content on the equilibrium precipitate phase Effect of Mo and W Elements and Content on the Mechanical Properties As for Inconel 740H, the effect of Nb, Al and Ti on the equilibrium precipitation of the alloy was analyzed by software calculation.
The tensile properties at room temperature, 600, 650, 700, 750 and 800℃ respectively were tested, and the results are shown in Table 4 and Fig. 7.

Introduction Copper is one of the metals most extensively used in industry, either because of its intrinsic properties or as a base for further formation of metallic films.
Electroplating copper films have been widely investigated with regard to their structural characteristics, electrical properties and corrosion resistance [3, 4] but less care has been yielded to their mechanical behavior and its relation to Electroplating parameters.
One of the most important mechanical properties of the coatings is the adhesion strength, which is defined by The ASTM as the "condition in which two surfaces are held together by either valence forces or by mechanical anchoring or by both together" [1].
(Teer ST-30) Scratch test is one of widely used, fast, and effective methods to obtain the critical loads that are related to adhesion properties of the coating [5, 6].
A total number of 20 experiments with three factors (2k +2k + 6, where the number of factors k = 3).

The input material properties of scroll expander were taken to be the same as experimental model.
The properties of measurement points were determined by thermodynamics theory.
The maximum deviation was around 17.5%, which might be mainly caused by the treatment of fluid properties.
Alternatively, expander geometry is also a factor to affect volumetric efficiency.
The laps of the expander geometry and rotation speed are also important factors to influence volumetric efficiency. 4.

LLDPE has better performance than LDPE on such aspects as mechanical strength, stress cracking resistance, heat resistance, cold resistance and warping resistance, so the mechanical property of LDPE can be improved if it is used together with LLDPE[4-6].Changing the property of LDPE by using Aluminosilicate Zeolites to make refreshing film which has high permeability was studied in this paper.
And then test the mechanical properties of the film based on the criteria listed in Tab.2.
MD: machine direction; TD, transverse direction Fig.1 The tensile strength Effect of zeolite on barrier properties of LDPE film Tab.3 shows that the amount of zeolite had some effect on the barrier property of LDPE film.
Crystallinity of modified LDPE film is the main factor to affect OTR.
Effect of zeolite on thermodynamic properties of LDPE film In order to verify the changes of the mechanical and barrier properties of modified films, five kinds of samples were done DSC differential thermal analysis, as shown in Fig.3 and 4.

Bonding strength of the interface of film-substratum is an important factor and key problem that influence the reliability and usage of film-substratum system.
Otherwise, hard film has been used to protect the parts in hard environment, because of the superior properties of wear resistance, high temperature resistance, and corrosion resistance [3-4].
The method avoids the directly contact between the measuring instruments and film effectively, without mechanical force and friction, and decreases the effects of non-interface factors.
The SEM images of impact point affected by 900mJ and 1000mJ laser power is expressed in Fig.4.
Effect of residual stresses on mechanical properties and interface adhesion strength of SiN thin films.

These factors change the shelf-life of yoghurt and finally cause spoilage in yoghurt.
The reason of this is that the microbial contaminations due to various effects and the factors within its structure.
On the other hand, the rapidly rising expectations on packaging sector can be summarized as improved barrier properties, heat consistency, high resistance against outer factors, being light, cheap and resistant, being visually attractive, etc.
The type, magnitude and stability of these interactions are effective on determining the physical properties of yoghurt coagulum.
These properties show us that it can easily form a chemical bond with polypropylene.
