Fe has very little solubility in Al in its solid state and precipitation of these Fe intermetallics (IMC), in the Al matrix decrease mechanical properties, due to the Fe IMC brittle nature.
Fe has very little solid solubility in Al, therefore during solidification Fe easily develops into highly faceted Fe-rich intermetallics (IMC), leading to a reduction in mechanical properties [1,2].
This is apparent due to the development of Chinese scripts α-Al15Si2Mn4 which influence the phase [mol] content, indirectly affecting the stability of other phases.

The Electrical properties were studied by using two-probe method.
This issue affects all aspects of economic and social development.
Calcium cobaltites are intrinsic semiconductor that takes on extrinsic properties when we doped with impurities that change its electrical and thermal properties [9].
First reason is the activated oxygen vacancies, a large number of charge carriers, and temperature dependent diffusion are all factors that contribute to this effect.
Charge carrier, defects, phase change and impurities all these factors influenced the Seebeck coefficient of a material [15].

Three cases were used to study these factors and obtain the results correspondingly.
The following results display the wall shear stresses and how it affects the pressure losses.

Development of Mathematical Models for Prediction of Weld Bead Geometry of GTAW Stainless Steel S.M.Ravikumar1, a * and P.Vijian2, b 1Department of Mechanical Engineering, M.A.M.College of Engineering, Tiruchirappalli, 621 105, Tamil nadu, India. 2Department of Mechanical Engineering, Government College of Technology, Coimbatore,641 013, Tamil nadu, India.
The quality of the joint can be defined in terms of properties such as weld bead geometry, mechanical properties and distortion.
The heat-affected zone, the molten metal, and the tungsten electrode are all shielded from atmospheric contamination by a blanket of inert gas fed through the GTAW torch.
The weld bead geometry plays an important role in determining the mechanical properties of the welded joints.
The significance of the factors on overall quality characteristics of the weldment has also been evaluated quantitatively by the analysis of variance method (ANOVA).

The investigations of the application-relevant properties of the UNCD/a-C films revealed that they are attractive for a number of mechanical, tribological, structural, and biomedical applications.
In addition to all its outstanding mechanical, tribological, thermal, optical and chemical properties, diamond possesses the advantage of being inherently biocompatible [3,4].

The main research of this test is the influence of different water pressure, water jet forward speed and target distance factors in forming process.
In this test, using DWJ-A/B series CNC universal water jet cutting machine shown in Fig. 1, made in DARDI Company in Nanjing, process out of the five long grooves, calculate the average of the five long grooves depths and observe the surface quality of sheet metal influenced by different combination of factors.

However, due to the sheet metal under pressure to bend, the object which sticking in the sheet also generated curved which cause bending moment affecting the simulation results.

Introduction High strength aluminum alloys, such as 7075-T6 and 2024T3, are utilized extensively for aerospace vehicles due to their excellent mechanical properties [1].
Influence of DNS complexing agent on the properties of conversion coating.
Analysis results of table 2 are as follows: the main factors of affecting thickness are the fluoride content, followed by the amount of complexing agent DNS.
The main factors affecting the corrosion resistance is also the content of DNS, followed by voltage level.
Comprehensive analysis of the results of three properties, A1B3C1D2 is the best experiment project.

The testing results showed that paraffin was absorbed into the holes and cracks of EP, and CBBP had not linear change of various properties versus amount of cement or paraffin.
Among the discussed PCMs, paraffin had desirable properties, such as high heat-fusion, little or no supercooling, thermal and chemical stability [3].
As shown in Fig. 2(b), adding the organic paraffin was negatively affected on the mechanical performance of cement bricks[3].
Taking into account the cost of cement, water absorption was not a major factor.
The effect of cement was more important on the mechanical properties, as shown in Fig. 3(b).

It consists one of the most important factors for high restoration parts durability.
By a relative research [5, 6] it is shown that drying shrinkage and thus composite mortars final strength, is affected by a range of factors as the fiber volume percentage, the temperature and the relative hydration.
It is reminded here, that factors affect the final properties of reinforced mortars are the type of fiber, the fiber volume percentage, the physical features of fiber and especially its length to diameter ratio [4].
The worse workability of fresh mortars will lead to increased internal flaws and high porosity values and thus to worse physico-mechanical properties.

The lower bond strength obtained from these adhesives can be attributed to several factors.
Nanoindentation has enabled investigation of mechanical properties on a very small scale.
Other mechanical properties can also be determined from this experiment.
For the phosphoric acid-etching system both dentin and enamel suffer loss of mechanical properties due to aggressive etching.
For the self-etching MDP-containing system, the interface is rather thin with minimal loss of mechanical properties.
