Heat load is the major factor to cause ablation and heat crack of piston head, and mechanical load is easy to bring crack at piston pin seat.
As regarded as the symmetrical entity, a 1/2 3-D solid model including piston and pin is established by using the software Pro/E, and some unimportant factors, such as spot fillet, bevel edge, oil hole and so on, are neglected in the model. 1/2 FEA model is introduced to the ANSYS10.0 software.
Considering the nonlinear material properties, the Newton-Raphson equilibrium iterative method is applied to calculate the nonlinear responses.
The temperature change will cause the thermal load and the deformation, but the deformation will be able to affect the quantity of heat transmission within the piston [5].
This fact makes clear that the explosive pressure of fuel gas is the main factor to cause the stress concentration.

The quality of the product is verified by testing different properties.
Introduction Manufacturing processes produce constantly vast amounts of data concerning the product quality and factors that affect it, including the chemical composition, process settings and measured values of the process variables.
An improvement in the prediction accuracy of a rolling temperature leads to an economically significant improvement in the quality properties of the final product, namely flatness and mechanical properties.
There are two individual mechanical property data sets gathered in different factories.
The mechanical properties are measured with standardized tests and they are performed regularly for each customer order to assure the quality.

Because the triaxial stress degree and maximum tensile stress are a main factor deciding the occurrence of the ductile fracture.
When corresponding parameter of the material reaches the critical value, the material begin to ductile fracture.Due to the ductile fracture relating with material properties, history of deformation, and processing parameters etc, selecting a reasonable critical value to predict occurrence of ductile fracture is necessary for the specific process of ductile fracture.
Conclusion In the process of plastic forming of metals, ductile fracture can make the material produced unnecessary waste on the utilization and economy, and is an important factor affecting the forming limit of metals to improve seriously.

Above 700°C, formation of porous oxides at the film surface deteriorates their mechanical properties rapidly by the.
Introduction Due to their excellent mechanical and tribological properties hard coatings, particularly transition metal nitrides, have been widely applied to cutting tools, molds and other mechanical components to increase their lifetime and performance [1].
During service at high temperatures above 973K [2], their mechanical properties are degraded rapidly by the formation of porous oxides at the film surface.
However, the mechanical properties of Al-rich film, especially high temperature impact resistance were rarely reported.
Fig. 4 shows mechanical properties of the coatings such as hardness and residual stress.

Therefore, all the progress in the field of press production is associated mainly with the development and improvement of technological preparation, providing improved mechanical properties [1,2,3,4].
Therefore, the nature, size and distribution of disperse particles as well as mean size of the grains affect the strength properties of ultra-fine-grained materials [7,20].
This leads to an increase in the strength properties of the alloy and retention of good plasticity.

Although slightly porous structures can attain static properties equal to those of fully dense materials [4–6], a notable decline in dynamic properties is observed in materials fabricated using laser powder bed fusion (LPBF).
For instance, Solberg et al. [7] highlighted material porosity as the primary factor affecting the fatigue limit of LPBF 316L in rotating bending fatigue.
Given the absence of significant defects, it can be inferred that the failure initiates at microstructural features being closely related to the strength properties.
The findings contribute to a better understanding of the factors influencing fatigue behaviour and can guide the design and optimization of additively manufactured components for enhanced fatigue performance.

Several factors associated with the restorations’ surface quality are surface roughness, wear resistance, and mechanical properties [6, 19].
Among these properties, surface roughness has a major impact on the biofilm adhesion and maturation.
