It was shown that the surface properties may vary within a wide range.
As a result of implantation the surface enhances catalytic activity and modifies the mechanical properties.
Introduction Environmental safety of the thermal installations of equipment is determined by several factors, including the degree of combustion.
The advantages of this method compared to conventional methods of coating (diffusion alloying, melt alloying of, doping during epitaxy) include the following [3,4]: − chemical and physical properties of the surface can vary over a wide range without regard to the bulk sample properties such as the solubility limit; − no interface between the implanted layer and the substrate material, which often are the cause of corrosion due to the contact potential difference of the source or the deterioration of mechanical properties due to insufficient adhesion properties between the layers; − consumes very small amounts of the alloying material, therefore, if necessary, it is possible to use expensive and rare elements without significantly increasing the cost of the process (for the catalysts, the applied corpuscular doping on oil-gas burner to be applied 0.02% of platinum by weight of the inner burner screen for effective afterburning final oxidation of fuel and harmful impurities); − the process

Differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and fold-deploy shape memory tests were used to characterize the feasibility of two-stage curing, thermodynamics properties and shape memory performance of these polymers.
Secondly, the SMPs usually have low crossing-link because we hope they possess low folding package temperature, as a result, the mechanical properties will be deteriorated which limiting the application of SMPs using in space.
After two-stage curing, the materials’ stability and heat resistance will be significantly improved, though they lost the shape memory properties.
Thermodynamics properties including the Tg and storage modules of the composites researched by dynamic mechanical thermal analyzer (American, TA Q800) DMA, the sample size was 25mm×5mm×1mm.
The lower crosslink-density may lead lower Tg due to crosslink-density was one of most important influencing factors for Tg, Generally speaking, Tg might characterize the heat resistence of materials, hence, the results proved that heat resistence of SMPs had been enhanced effectively by the second curing stage.

An assembly, the quality of the drilled holes highly affects the joint of two or more structural components.
In the last few decades, glass fiber reinforced plastics are used widely in primary structures due to their good properties.
Palanikumar and Valarmathi [2] have concluded that the feed rate and drill diameter are the highly important key factors followed by the spindle speed on delamination.

Introduction Duplex stainless steel during manufacturing process may cause the precipitation of some harmful second phases, for instance, the σ phase, which seriously deteriorates the mechanical properties, increases the opportunity of stress corrosion and limits the applications of DSS [1-7].
Because the precipitation of σ phase can significantly affect the mechanical properties and corrosion resistance of duplex stainless steel, it is necessary to clarify the precipitation mechanism and influencing factors of σ phase during solidification.

It is demonstrated that MIF is the most efficient method of DMNs allowing one to obtain the bulkiest nanostructured samples with enhanced mechanical properties.
The mechanical properties of MIF-nanostructured materials will be presented with an emphasis on the strength and temperature of superplastic deformation and perspectives of applications of these materials will be shortly discussed.
These stages exist at any temperature of deformation, any stacking fault energy, phase composition of material; all these factors affect the strain levels dividing the three stages.
The mechanical properties of nanostructured materials processed by ECAP (followed by extrusion) and MIF are quite similar.
High-temperature mechanical properties of MIF-processed materials are also similar to those of ECAP-ed ones.

Introduction Steel fiber concrete is common concrete which is added with appropriate amount of randomly distributed short steel fiber, forming a multiphase, multicomponent cement-based composite material with excellent physical and mechanical properties [1].
The properties of other materials used are given in Table 1-Table 3.
Effect of matrix strength and steel fiber volume ratio on SFRC compressive strength Two factors influence compressive strength, consequently, factor A and B are defined.
As the steel fiber volume content is small, the calculation model assumes that there are no cross influence between two factors.

An elasticity test was used to examine the mechanical properties of composites, specifically between sisal and LLDPE.
Cyras, et al. [14] researched the mechanical properties of sisal-polycaprolactone composites.
This in turn increased the adhesion efficiency between the fibre and the polymer, which improved the mechanical properties [20].

The purpose of this study is the determination of the force requirements by air bending of structured sheet metal and an analysis of influence factors on the bending force.
The bending force of structured sheet metals is affected not only by material properties.
By the existing calculation methods it is not possible to consider these factors.
In a previous work [10] the bending force was calculated with consideration of the changed mechanical properties of structured sheet metal.
The mechanical properties of the investigated materials were determined by tensile test according to DIN EN ISO 6892-1 (Table 1).

Results showed that the designed porosity significantly affected the mechanical strength, density, and infiltration rate of the PC.
The void and pore structure are important properties that influence the performance of PC.
Besides, PCs with mineral additives exhibited higher performance in engineering properties, cost savings, and energy efficiency [8,9].
These results proved that porosity was the most important feature of PC, significantly affecting its permeability.
However, PC cannot be used for reinforcement, high-speed roads, and heavy-load traffic roads due to its mechanical properties and the open pore in the structure.

However, all three factors were found statistically significant in the production of nano-scale fibers.
Introduction The market for carbon fibers is dominated by fibers made from polyacrylonitrile (PAN) due to their combination of good mechanical properties (high-strength, low-density composite materials and high break strength (particularly tensile strength, and reasonable cost).
This approach enables experimental investigation of the individual factors and the interactions of the factors (variables or parameters) simultaneously.
It can be used for studying the effect of several factors at different level and their influence on each other.
The drastically contact angle value was achived using highest value of both factors of 19 wt.% and 15 cm, respectively.
