The mechanical properties of cemented carbide substantially depend on its composition and WC particle size.
Their mechanical properties can be modified over a broad range by changing the content of the binding Co phase and the WC grain size [6].
A reduction of the WC grain size, on the other hand, increases the hardness and improves other mechanical properties [7,8].
The nominal chemical composition and some physical as well as mechanical properties for all these tool materials used in the tests are listed in Table 1.
Tool life is the most basic and primary indicators to determine the advantages and disadvantages of cutting tool material performance, it is mainly achieved through the tool wear test data, in general, many factors affect the tool wear, cutting speed is the most significant factor affecting cutting tool wear and tool life after the workpiece, the tool material and tool geometry were selected [16], therefore, all turning tests were carried out on a conventional lathe equipped CA6140 with stepless speed change device and a main power P=7.5KW as well as a maximum number of revolutions n=1460 min－1, continuous dry cylindrical cutting.

The properties of the soft matrix, interphase and rigid particles (size, shape, material properties) can have a significant effect on the global behavior of the composite.
The presence of the interphase between particles and matrix can significantly change the final global mechanical properties of the composite.
A micro-crack of length corresponding approximately to the distance between the particles was modelled and the corresponding values of the stress intensity factors KI and KII and consequently the angle a were calculated.
Consequently, the global behavior of the polymer particulate composite is affected too.
This effect is strongly material properties of matrix and interphase dependent.

Such a temperature is higher than classical tool steels annealing temperature and could lead to a fall of the mechanical properties.
This tool steel grade looses a part of its mechanical properties at high temperature.
The solution not only combines the different mechanical properties in one tool but also has a economical benefit as it offers tool cost consequent reduction.
It is therefore noted that the piston corners are more thermally affected compared to the central part of the piston.

Introduction Composite laminates are widely used in aviation and aerospace because of their excellent properties such as high strength weight ratio, high stiffness to weight ratio, low density, corrosion and fatigue resistance, and designable features.
Mechanical linkage has good debonding resistance with no curing residual stress, and it is hardly affected by environmental factors.
Mechanical linkage can increase the weight of structures and may affect the streamlined external shape of airplane.
Mechanical linkage is usually used on thick structure assembly.
This method has some excellent properties such as good debonding resistance, low equipment requirements and good structure strength recovery.

Research on Calculation and Analysis of Clamping Force of Power Cut Self-Locking Device Xi Chuankai1, Zhao Dong1,a*, Cai Dongmei1, Fan Zhuangzhuang1, Zhou Yan1, Qin Lixiang1 1School of Mechanical Engineering, University of Jinan, Shandong Jinan 250022, China ame_zhaod@ujn.edu.cn Keywords: Self-locking device, Clamping force, Performance influence, Optimization analysis Abstract.
This paper mainly studies the principle of self-locking device, the calculation of clamping force, the performance factors and the analysis of the elastic deformation force of the lock ring in order to meet the performance requirements of hydraulic cylinder in the process of wind system lock.
The lock ring angle ranges from 20 degree to 24degree.Bychanging the properties of different materials, the value of f1is taken between 0.05 to 0.15.Andf1 is the friction coefficient between the shell body and the locking ring.
The clamping force can also be expressed as follows: W=Qf2 (4) Q:Q is out cylinder load with the direction to the right Based on the above analysis, it is found that the elastic Fk of elastic element is an important parameter which affects the performance.
FK=Qtanα+φ1tanφ2-1=18.5kN, W=FK+Qtanα+φ1=1930kN Conclusion In summary, the locking ring angle, the friction coefficient and the force of the elastic element are the important parameters which affect the hydraulic cylinder locking performance.
