Relations for an assessment of conventional mechanical properties from quantities obtained by small punch test are presented.
Also it has been applied in determination of local mechanical properties such as heat affected zones of welds [4] or hydrogen embrittlement of steel [5] and characterization of mechanical properties of steels, light alloys and composites [6, 7, 8, 9].

Since the major risk of wire breakage, deflections of electrodes were affecting the performance accuracy of EDM operation.
It reports on the Micro EDM research involving the optimization of the process parameters surveying the influence of the various factors affecting the machining performance and productivity.
Micro Electrical discharge machining (µEDM) is especially suitable for manufacturing micro-components due to its thermal material removal mechanism, which allows an almost process-force free machining independently of the mechanical properties of the processed material, Yi Qin [2].
A Single parameter change will influence more significant in output performance .Hence various affecting factors the process has to understand to get optimal solutions.
Experimental results indicate that peak current is the most affecting factor in the Micro-EDM process qualities for SK3 carbon tool steel while pulse off-time had a significant interaction with that.

The Effect of Powder Size on Thermoelectric Properties of 95%Bi2Te3-5%Bi2Se3 Alloy S.J.
It is expected that microstructure and oxygen content of consolidated alloy vary with initial alloy powder size and this effects will be able to affect the thermoelectric properties.
It is indicative that the higher peak intensity is relating to the preferred orientation of grains and the statistical distribution of basal planes will affect the thermoelectric properties by scattering factor and carrier mobility.
Two factors can affect the electrical registivity.
It is well known that the power factor [8] is descried as α2/ρ is also another expression of thermoelectric properties and thermoelectric figure of merit (z) is proportional to power factor.

If loads affecting the system are not sufficiently known, mechanical strength may be exceeded and the system may fail.
Summing up, there is no comprehensive approach that accounts systematically for all influencing factors, such as ingoing product properties, disturbances, control steps, manual operations, machine accuracy, etc.
The example of the tripod system shows that component properties like geometric variations as well as a wide range of uncertain factors during assembly could affect the expected function.
By a consistent description of uncertain properties in the states and the influencing factors in the processes, it is a basis for a holistic approach of uncertainty analysis.
These are a) geometric, b) material, c) mechanical, d) electrical, e) economical and f) additional properties, Fig. 3.

Then, the factors affecting the quality of coating should be analyzed.
TiO2 has high melting point and mechanical strength.
Factors affecting the quality of coatings During the exploration of fabricating thick ceramic coatings, it was found that the spraying parameters, spraying powders’ characteristic and morphology and the substrates’ conditions all affected the adhesion and quality of the coatings.
It showed that deposition efficiency relied on gas temperature, powders’ properties and especially, the substrates’ ductility.
The ductility could affected the deposition of second pass.
