Properties such as these are influenced by factors like sintering temperatures, reinforcement, powder compaction pressure, particle size, reinforcement volume fraction and cooling times at sintering temperatures.
A composite matrix is determined by many factors, including the composition of the reinforcement particles, the solubility of reinforcement particles, and other factors.
In a wide range of studies, ceramic reinforcement in the Cu matrix improved its mechanical and tribological properties, but it adversely affected its electrical conductivity.
Properties Table 1 shows the mechanical, electrical and thermo physical properties of copper alloys and composites.
The sintering temperature impacts mechanical and tribological properties (hardness and density).

In this equation, factors that affect the seismic response of the equipment such as the ductility, resonance, site, and relative height effects are all taken into account.
However, as the dynamic property of equipment varies, the ap values given in Table 1 might not represent the correct response.
It can be seen that the component amplification factors do vary for different equipments instead of stay at the lower and upper bound of 1.0 and 2.5, as specified in Table 2.
On the other hand, these factors, when normalized by multiplying 0.4SDS, are comparable to the spectral acceleration SaD specified by the code.
The average component amplification factors for all four types of equipments are comparable to the spectral acceleration SaD specified by the code when normalized with respect to the PGA.

Potential application of this method is possible to see in noncontact method of measurement dimensional changes of textile substrates under mechanical stress.

Many works have been conducted to produce bulk materials with superior properties, however when it concerns wear properties, surface modification is preferable.
For example, laser surface melting (LSM) technique has been widely used to improve surface properties of alloys for improving hardness, corrosion and wear properties [2].

A variety of criteria for failure assessment such as crack-growth-typed failure and material-degradation-typed failure criterion require mechanical properties (flow properties, residual stress and fracture toughness) of target material in order to be carried out the quantitative and accurate assessment.
Since conventional methods for mechanical properties cannot be applied to in-service structures due to their destructive nature, instrumented indentation technique (IIT) was adopted to evaluate in-situ material properties of them.
Indentation-Derived Mechanical Properties Derivation of Tensile Properties Extracting Representative Stress and Strain The contact mean pressure, Pm is expressed as: 2 max a L Pm π = (1) where Lmax is indentation load and a is contact radius obtained from indentation curve analysis [1].
