Titanium alloys are widely used in aerospace and automotive industries due to their excellent mechanical properties, however, the formability is limited, which is an issue during forming.
The formability is usually affected by many factors such as temperature, strain rate, etc.
However, it has promising properties in terms of mechanical and fatigue strength as well as fracture resistance [5].
In [5] it was shown that the alloy has well-balanced properties in terms of mechanical strength, fatigue strength and fracture resistance, therefore the alloy is valuable for industry and can replace conventional titanium alloys such as Ti Grade 2 and Ti Grade 4.

The drying process, which consumes considerable energy and greatly affects the molecular structure and properties of agar, is important.
So the product dried at higher temperature (100℃) is feasible and the properties of agar product meet the demand of use.

Hybrid metal matrix composites (HMMC) are advanced materials which are not simply depicting in improvement of mechanical properties but also on characteristics of machinability for thorny shapes to machine.
Introduction The development of mechanical industry is associated with indeed of materials with eminent properties such as superior hardness, high toughness and good impact resistance.
Explore for new, high strength to weight ratio materials with better strength and toughness has guided to the improvement of a new age group of materials, while their properties may generate key challenges in machining operations.
Sivasankar et. al. [2] investigated the particle swarm optimization process for machining of ZrB2-SiC composite and found that the machinability of workpieces increases with increase in volume percentage of SiC till it reaches 25% then it starts decreases, pulse off time of 1 μs & on time of 7 μs is preferred as excellent combination and ANOVA shows that tool & pulse on time are the significant factors.
MRR is predominantly affected by Current then followed by the pulse on time, off time and tool lift. 5.

Apart from affecting workers' lives, construction accidents directly impact project sustainability.
The damage affecting individuals can be described as a social impact, while the damage affecting finances can be described as an economic impact.
Social impact pertains to harm inflicted on individuals, whereas economic impact pertains to harm affecting the economy.

The fine blanking process with stepped-edge punch is affected mainly by sizes of the die.
The negative clearance 'c (Fig.1) is an important factor affecting the hydrostatic stress of deformation zone.
The positive clearance c shown in Fig. 1 affects the separation of the part and the size of burr.
The other parameters of the forming tools and the mechanical properties of Q235 steel are given in table 1 and table 2 respectively.

And the experimental data of the pushed method are free from the influence of random factors.
Quantitative characterization and evaluation of coating-interface bonding properties of substrate material has always been the difficult problem in the surface-engineering technology research.
So far, a quantitative test method used for high performance coating adhesive strength of combining has not yet obtained, data dispersion small, influencing factors few, characterization parameters simple but physical meanings clear.
In order to solve this problem, the pressure-pushing is put forward in this paper, which is not affected by viscose bond strength limit.
Comparing the results of these two methods, the averages are equal results on the same coating materials, of which the deviations are among the random factors’ scope.

Especially, the issue of binding force between
CBN composite deposit and matrix that seriously affects the cutting life is still unsettled.
Firstly, the factors influencing the electroplating technique parameters, such as the area ratio of cathode to anode, temperature, PH value, the current density of electroplating technique parameter, stirring role and current of commutation were reasonably selected [1].
The equal height of the CBN abrasives in composite deposit is affected by abrasives size, order of planting abrasives and unevenness of matrix.
It suggested that cubic nitrogen had not flake off from the composite deposit and had extraordinarily great wear-resisting property.

The mechanical properties depend upon the number of graphene layers and its internal defects.
The lower thickness of the intermetallic compound has been reported to lead to higher mechanical properties.
The mechanical properties were improved by the incorporation of the nickel interlayer.
The degree to which the sample can be heated softened and melted locally is manageable by two factors, the welding current (I) and the time (t) for which the current is used.

Carbon, aramid and glass fibers are inherently superior to conventional textile fibers in
terms of mechanical properties as well as other chemical characteristics.
As a result of experiments, it was concluded that the hybridized materials has shown better performance than individual reinforced filament yarns in terms of mechanical properties.
Introduction Carbon (CF), aramid(AF) and glass fibers(GF) are inherently superior to conventional textile fibres in terms of mechanical properties as well as other chemical characteristics.
This would affect seriously with hybrid yarns containing CF.
Even filament distribution over yarn cross section is a very important factor to bear tensile loads.

Published literature is rich with investigations of mechanical properties of composites, but fewer publications are focused on thermal properties.
Their mechanical behaviours have some common features [7].
The properties of nanocomposites, like a normal composite, depend on its components and their interface properties.
Other factors may overshadow the potential advantages that these layers can offer to the thermal conductivity of nanocomposites.
The intention of this paper is to review and compare some correlations between two different nanocomposites in order to investigate how deeply we can understand the thermal transfer mechanisms in composites and the factors which affect their thermal conductivity.
