Diamond grain size is the main factor that determines the mechanical properties of PCD, and it is usually in the range between 1 to 80 µm.
Application of PCD is not only restricted to mechanical engineering, it can also be used as a high temperature electrical or optical devices.
The layer of PCD that is subjected to high temperature but not enough to be melted is called heat affected zone (HAZ).
HAZ is unavoidable in all thermal processes and emerges in a few microns underneath the surface that is affected by heat.

Environment temperature and loading condition will greatly affect its performance.
Low temperature bending creep test of asphalt mixture The properties of the material.
When the factors mentioned above are changed, the asphalt mixture will have different properties as elasticity, viscoelasticity, viscoplasticity and plasticity etc.
Because of the complexity of the rheological model of asphalt mixture, it’s unable to show viscoelastic property of asphalt mixture by a single mechanical component.
Conclusions (1) The Burgers model established in this paper can precisely describe viscoelastic properties of asphalt mixture based on the creep test of base asphalt and SBR modified asphalt (2) The methods of determining relaxation modulus are feasible based on the bending creep test data and time-temperature equivalence principle.

The optimization of the processing parameter is a method which influence the electrical conductivity and mechanical properties of the CPC.
Hence, these cause the mechanical properties of the material to decrease and in agreement with others research findings [24], [26], [27].

The Post-Yield stiffness was not affected by the change in bolt gauge.
Many factors can affect the behaviour of these components such as concrete-infill grade and slenderness ratio of SHS face [10].
The samples were cut from the same SHS tube to eliminate any discrepancy associated with the material properties of the SHS.
The Post-Yield stiffness was not affected by the variation of bolt gauge.

Generally, W/B is a significant influencing factor on properties of concretes or mortars.
Its physical properties are given in Table 2.
Specimens in the forms of 100 mm ×100 mm ×100 mm cubes and 100 mm ×100 mm ×300 mm cylinders were cast for measuring the mechanical properties of UHSC.
(1) Ultra-low W/B between 0.14 and 0.22 at a constant increment of 0.02 affected the mechanical properties of UHSC remarkably, while RPC or UHSC with coarse aggregate
Explosive Spalling and Residual Mechanical Properties of Fiber-Toughened High-Performance Concrete Subjected to High Temperatures.

The input parameters in the model are speed, feed, and depth of cut apart from tool geometry and material properties.
Residual stress is actually generated under the comprehensive influence of complex process and geometric variables, and other important factors, such as residual stress of the previous processing is also difficult to consider in the analytical model.
The constitutive parameters of the constitutive model are acquired by SHPB experiment that simulates the large strain and high strain rate properties of materials under the metal cutting environment.
Because the influence of some complex factors, such as cutting, cutting tool geometric parameters, cooling condition, and the recent high-profile microstructure change and size effect and so on, are needed to considered, and lots of research have been carried out at home and abroad[2].
For the residual stress is essentially the combined action of the plastic deformation, cutting temperature and phase transformation, the comprehensive prediction model considering these factors is badly needed to predict the residual stress accurately.

It can be concluded that level of V concentration at the beginning of TD process is a vital factor for the forming of VC layer.
This paper deals with how the beginning V concentration affects the result of TD process on Cr12MoV.

Then the test bodies were subjected to determining physical and mechanical properties and physical and chemical characteristics: Physical and mechanical parameters: - Determination of increase of initial strengths (methodical procedure acc. to ČSN EN 14488-2), - Determination of specific density (ČSN 722447), - Determination of tensile strength at bend (ČSN 722450), - Determination of compression strength (ČSN EN 12190).
As regards the rise of initial temperatures, the developed material can meet the requirements placed on Sector J2 and the accelerating admixture is not the factor that would adversely affect the composite resistance to extreme temperature effects.
The positive effect of the presented measures on resistance to high temperature effects can be documented in the developed composite by comparing its properties with a commonly used sprayed concrete.
At higher temperatures the mechanical properties of the standard shotcrete are very low with its practically total destruction.
However, at extreme temperatures (i.e. 1000°C or 1200°C), the mechanical properties of this composite are significantly decreased.
