The drying temperature affect the mechanical properties of peroxide-vulcanized natural rubber latex films as the tensile strength values tended to decrease at drying temperature above 120 °C.
Measurement of Mechanical Properties.
Effect Of Prevulcanization Temperature And Time On Crosslink Density Mechanical Properties - Tensile Strength.
Effect Of Ageing On Mechanical Properties Of Natural Rubber Latex Films.
Although crosslink density is an important parameter, other factors also contribute to the high strength property of peroxide-vulcanized natural rubber latex films.

That is to say, there is effect of environment on the mechanical properties of the alloy.
Therefore, it was inferred that the effect of tensile environment on the mechanical properties of the alloy is actually the effect of hydrogen in the environment on the mechanical properties of the alloy.
Fig. 4 The mechanical properties of FeCoNiCrAl0.1 alloy tested in various environments.
On the other hand, the effect of hydrogen on the mechanical properties may be related to hydrogen affecting the formation and diffusion of vacancy.
There is obvious effect of tensile environment on mechanical properties of FeCoNiCrAl0.1 alloy.

Various types of metals and alloys are used for medical implants due to their excellent mechanical properties and corrosion resistance; however, their lacks of osteoinductive properties bring about the introduction of biomaterials which can help enhancing the bioactivity between the bones and the implants.
Introduction Orthopaedic and dental implants made of metals and alloys have been used widely because metals and the alloys provide excellent mechanical properties as well as good corrosion resistance [1,2].
The L8(27) orthogonal array with 7 factors and 2 levels was selected as showed in Table 3.
After, the Taguchi method, affected factors were selected for a further statistical analysis of significance, thickness fit-equation, and optimal condition was obtained by a full factorial and response surface methods.
From results in Fig. 2, the factors and interaction that affected to the coated thickness were: the feed rate; the feed rate*air pressure volume; and the feed rate*time*air pressure volume because the p-value less than 0.005.

During dry-wet spinning, diffusion is very important for the formation and mechanical property of fibers.
Several factors which affect the coagulation process including concentration and temperature of coagulation bath were discussed respectively.
Introduction Cellulose acetate (CA) is a modified natural polymer with awide range of properties [1, 2].
The solubility of CA in various solvents depends on several factors, including the degree of substitution (DS) and the solubility parameter of the solvents.
The coagulation bath concentration is also an important factor that affects the final content of HAc in the filament.The influence of concentration of solvent in the coagulation bath on diffusion of solvent during the coagulation process is very complex.

Refining the microstructure of steel improves its mechanical properties (e.g. toughness).
In this work SAE 52100 specimens were exposed to repeated induction heating process and rotation bending tests were performed using single- and repeatedly heat-treated material in order to investigate the influence of this cyclic heat treatment on the mechanical properties of SAE 52100.
It is therefore of crucial importance to improve the mechanical properties of the material in order to reduce crack initiation and propagation.
The stress intensity factor K1max was calculated by equation shown in Eq. 1.

The main reason is that the non-uniformed interface between the wafer and the machine-pad adversely affects the polishing performance and ultimate surface uniformity.
Properties of CU.
That is, the CU is the product of two factors.
The first factor to the right of the equal sign measures the within-groups component, that portion of CU attributable to dispersion among group members.
The second factor measures the between-groups component, that portion of CU attributable to differnces in means across groups.

The level of mechanical anisotropy was affected by the initial composition of the slurry and sintering temperature.
Pore shape anisotropy can affect such properties as mechanical strength and thermal conductivity in various directions of the material.
This could imply that the CS is affected not only by the introduced pores, but also by the microstructure of pore walls which is affected by the particle size distribution, composition, and sintering conditions.
These factors should be further examined.
This implies that the level of mechanical anisotropy is affected both by the introduced pores (formed by hydrogen gas) and microstructure of pore walls.

Carbon blacks are used universally as fillers in polymer matrix for mechanical, electronical and thermal properties improvement.
Plenty of studies show that the structure and surface properties affect the function of carbon blacks in polymer matrix intensively.
Such factors as interfacial interactions between rubber and carbon black, occlusion of polymers in the internal voids of the aggregates, and filler-filler interactions depend on the structure and surface properties of carbon blacks [3-7].
In order to understand the theoretical mechanism of reinforcement, the surface structures and mechanical properties of black carbons must be defined.
