The factors effecting the micro-hardness of the work-piece has been obtained.
Zhang et al. [3] investigated the effect of the EDM pulse current on the micro structure and the properties of the P20 specimen surface.
The micro hardness is reduced from the outer layer to the base metal after the heat treatment, indicating that the mechanical properties are changing of the machining surface.
The measurement of the micro hardness beneath the machined surface of AISI H13 was carried out using Vickers micro hardness tester to characterize its mechanical properties.
Hardness is unaffected by the input factors Fp and Tup.

Because the mechanical properties of microcellular foaming material is similar to petroleum-based plastics (PS), PLA foams have been considered as ideal alternative materials.
The addition of chain extender also can enhance the decomposition temperature and the mechanical properties.
Blended PLA foaming Different from the chain of PLA, the blends are multi-phase materials.The mixing of PLA with other polymers can not only improve the foaming properties of PLA, but also improve the mechanical properties of the products.
The molecular weight of the PLA was an important factor on affecting crystallinity and melt strength.
The mechanical/thermal properties of microcellular injection-molded Poly(lactic acid) nanocomposites.

The effect of friction and wear, the mechanical structure and operation conditions on accuracy recession of numerically-controlled machine tools were described and commented as the key point.
Many scholars at home and abroad have made studies in many aspects about what affects the accuracy recession of the numerically-controlled machine tool, however the basic theoretical research is also imperfect so far.
And the real measure showed that the dynamic changes of the accuracy could be analyzed precisely with comprehensively considering the geometrical and physical factors, which influenced the accuracy recession.
Apart from the impact of above mentioned friction and wear and the mechanical structure, CNC machine tools are also affected by operation conditions in different working conditions.
At present, the main deficiency of the research on accuracy recession lies in: that firstly, in the study of the influence of the friction and wear on the accuracy recession, the research on the influence of the physical properties related to the contact layer in the part of the conjunction, including microhardness of the surficial layer, internal stress, the degree of cold hardening, lubrication conditions of the boundary and so on, on wear properties is not sufficient; In addition, researches mainly adopt the method of experiments, but experiments will cause a large consumption of manpower, financial resources and material resources and the limit conditions of the experiment are numerous.

The imperfection of billets results in a reduction of mechanical properties and the surficial quality of the rolled product [20].
Many factors affect the quality of cast billets, such as stroke length, mould powder consumption, temperature, casting speed, mould flow rate.
The processes also face the change in mechanical properties attributable to the generation of stresses in the solidifying molten steel [13, 19].

Tendon cell growth factors.
Tissue engineering tendon research mainly includes the study of seed cells, scaffold materials research and Study on mechanical properties of.
The good structural compatibility has a certain mechanical strength.
Because the tendon is a kind of special organization, as the tendon tissue engineering stent material in addition to the above features, should also be bent, has toughness, can withstand a certain degree of tensile properties.
Bio derived material is the future of tendon fine texture of the major research project, with its closest to the body of the grid structure, biomechanical properties and active factor, it is conducive to cell adhesion, growth and functions.

The excellent properties of graphite for sealing materials can be defined as “perfect”.
In order to overcome these shortages, it is necessary to achieve dense, supplemented strength by impregnating metal and to improve the wear resistance, heat resistance, impact resistance, mechanical strength and other properties [1].
Therefore, the characteristics of large pores are the main factor that affects the quality of impregnation materials.
Therefore, large pores are the main factors that affect the quality of impregnation materials.
Material formulae are congenital factors that influence the characteristics of large pores.

The influences of reaction factors have been studied in detail.
Introduction The use of SMC in automotive industry as exterior body panels is increasing because of its high strength/weight ratio and good mechanical and ultimate properties [1].
Taking the economic factors into account, the optimal feed ratio is 1.02:1.
Considering the above factors, Suitable amount of catalyst is 1.0%.
Properties testing results showed that this kind of vinyl ester is suitable as thickener for SMC.

The mechanical properties of fibers exhibit considerable scatter, being affected by the natural variability in plant as well as the damage accumulated during processing.
Both damage in the form of kink bands [1-4] and geometrical variability are thought to affect the apparent longitudinal tensile strength of elementary flax fibers.
Model Mechanical damage.
Both factors are likely to contribute to the scatter of apparent fiber strength.
By contrast, the scale parameter, b, depends on the factor c relating the deterministic intact fiber strength fσ with its diameter; the value of c can be determined by, e.g., strength tests of intact fibers.

The stabilization process of CEB occur using various mechanical and chemical methods aimed at improving its mechanical properties, stability and durability.
Among these methods, MLR analysis gives a good precision on the estimation of the mechanical properties of CSEB [16–19].
This result indicates clearly the existence of the auto-correlation between the four studied factors of cement content, lime concentration, resin addition and compaction pressures.
Moreover, the results obtained from VIF test indicate clearly that there are no collinearity effects between studied factors, low values are obtained for the four considered variables (<5).

Influence of SBR on mechanical properties of cement mortar Various properties of cement mortar such as the tensile bond strength, flexural strength, flexibility and anti-impacting property are improved significantly by SBR addition.
mp/mc=0%mc=0% mp/mc=8%mc=0% Fig. 5 Second electron images of SBR latex-modified mortars cured for 28 days Interface structure between the aggregates and cement paste is a key factor affecting cement mortar properties.
The weak structure at the interface decreases the mechanical properties and durability.
