Studies have shown that preheating temperature is one of the most critical factors affecting the life of the diecasting mould [6].
The main factors affecting hair include: the temperature difference between the mould surface and the ambient air, mould surface emissivity, and mould geometric characteristics.
Studies have shown that the heat transfer coefficient hcontact is mainly affected by factors such as interface temperature, interface pressure, interface roughness, and the types of materials on both sides of the interface [13].

In Taguchi method, the raw data is transformed into S/N ratio values which adduce the most significant parameters affecting the material MRR, SR, KW and DD during the machining of Ti-Ni SMAs.
Four controllable three-level factors and four response variables were considered.

Herewith, in some cases, alternative fillers do not ensure the required physical and mechanical properties of WPC products.
Standard specimens for testing the WPC physical and mechanical properties were prepared by hot pressing.
The input factors of the experiment were the irradiation intensity (Z1, mW/m2) and the duration of exposure to UV irradiation (Z2, hours).
An increase in radiation power at a low duration of exposure to irradiation does not affect greatly the physical and mechanical composite properties.

The differences of macroscopic mechanical properties of concretes can be explained using the changes of their pore size distribution.
Introduction Pore structures and their changes of concrete are important factors to influence the mechanical property and durability of concrete.
The results showed in Fig.1 are consistent with the general development trend of mechanical properties of concrete.
This indicates that what affects the macroscopic properties of concrete most is not porosity, but the pore size which leads to the change of porosity.
And results by TPM also can explain the mechanical properties changes of concrete

Heat-aging effects on the material properties and fatigue life prediction of natural rubber were experimentally investigated.
This aging process results mainly from heat due to hysteric loss, and is affects not only the material property but also the fatigue life of rubber.
Elongation at break(EB) is very important factor in material properties and fatigue life prediction of rubber components.
We know that the material properties were a function of heat-aged period as well as temperatures.
Predicted fatigue lives of the rubber component were in fairly good agreements with the experimental lives within factors of two.

Common used self-lubricating tool has self-lubricating function, but its mechanical properties are greatly reduced.
But, solid lubricants may lead to the decrease of mechanical properties of tool materials.
ZrO2-TiB2-Al2O3 nanocomposite ceramic die material with good mechanical properties was fabricated successfully.
However, it also can reduce mechanical properties and wear resistance of the ceramic tool material.
The mechanical properties of nano-micro composite materials can be greatly improved.

Introduction One of the major world tendencies in the development of engineering industry is technological development and creation of high-tech materials that able to have the necessary physical, mechanical and chemical properties and, as a rule, having a certain structure.
The basic properties of the sintered porous slide bearings [9], are determined by their functional qualities: self-lubricity, good running-in ability, wear resistance and strength.
The combined method of the process has the wide range of controllable factors, affecting on the quality level of the formed surface, and therefore, it is convenient and effective to use in the forming process of the hard-to-punch and the heterogeneous materials.

Factors influencing in the technological capabilities of metal-ceramic sintered materials, during the finishing process.

Schreiber [16] confirmed that the mechanical properties of the wrokpiece material have a great influence on the magnitude and distribution of the residual stresses.
It is therefore of great significance to exactly evaluate the effects of all these factors including machining parameters, tool wear, material properties on the residual stresses induced by hard turning process.
This is mainly due to that all required material properties are not accurately known.
Wu and Matsumoto, and Lin et al [17, 27] used Finite Element techniques to determine factors, which affect residual stress formation and distribution in hard turning.
The magnitude depends on properties of work material under cutting conditions.

A number of factors need to be considered when developing numerical models for multipass welding, inluding: weld method (and heat input), weld geometry, bead sequence, boundary conditions and material model.
A particularly sensitive factor is the material model and, specifically, specification of hardening properties from room temperature and potentially up to the melting point.
Due to their different locations, the deformation history and, therefore the material properties, of these points are expected to differ, since: 1.
In reality a newly deposited bead will have an ‘as welded’ microstructure and material properties that reflect this.
The mechanical properties of the newly deposited weld bead will differ from those of the welding rod prior to welding.
