These alloys have good mechanical properties, corrosion resistance and die castability.
These factors cause the decrease of the Mg17Al12 phase volume fraction and the formation of new intermetallic compounds (Mg2Si, Al11RE3, Al2RE, Al4Sr, Al2Ca) which have higher stability at elevated temperatures than Mg17Al12 phase [2-7].
Thermal conductivity and thermal diffusivity are crucial parameters for metallic materials, because they affect the heat transfer rate in the processing process.
Based on results obtained in this paper, the main factor affecting the thermal diffusivity of Mg-Al, Mg-Al-RE, Mg-Al-Sr, Mg-Al-Ca-Sr alloys is aluminum content in α-Mg solid solution.

During a typical machining operation of such alloys, high cutting forces imposed by a tool on the work-piece material lead to severe deformations in the process zone, along with high stresses, strains and temperatures in the material, eventually affecting the quality of finished work-piece.
Conventional machining (CT) of Ti- and Ni-based alloys is typically characterized by low depths of cuts and relatively low feed rates, thus adversely affecting the material removal rates (MRR) in the machining process.
However, these excellent mechanical properties are generally paired with poor thermal conductivity, high abrasivity and high chemical affinity with common cutting tool materials, thus impairing their machinability [3,4].
Material properties of the alloy are presented in Table 3.

At the same time, its manufacturing quality has a certain impact on the aerodynamic performance of the aircraft, so its synthetic mechanical property is required high.
It is not only a structure part, but also a mechanical part.
The requirements of the comprehensive mechanical properties and the appearance structure are properly high.
The establishment of the surface models depends largely on the factor of no gap.
It will often affect the ultimately establishment of the surface model. 4.

Particularly, the following requirements are imposed on non-active surgical implants and pedicle screws – they must have a set of mechanical properties (strength, crack resistance), a certain microgeometry of the surface in order to ensure a strong fastening of the screws, good survival in biological tissue, to exclude their breakage and deformation in the patient’s rehabilitation period.
The chemical properties of the screw material are also important, which can be proved by the absence of unwanted reactions with tissues, intertissue liquids; as well as biological properties (lack of response of the immune system, good osseointegration) [1, 2, 3, 4, 5].
Taking into account the factors determined as a result of the analysis of the screw designs, the drawings and the digital 3D model of the screw sample were developed in the Siemens NX CAD system.
When choosing cutting modes, the following factors were taken into account: the material of the machined parts – either titanium or titanium alloy, the brand of the tool material and protective coating, the type and concentration of lubricating and cooling technology media, and the processing method.

For mass imbalance, bearing manufacturing defects, electrical motor noises, and other factors, the CMG produces periodic and broadband disturbance vibration to the spacecraft while controlling torque.
The large CMG also significantly affects the pointing precision of the optical path and the stability of the remote sensing satellite.
Measuring the natural frequency of large CMG The natural frequency of rotating mechanical systems can be measured in two ways: hammering and forced oscillation.
By contrast, forced oscillation gradually increases the rotation speed of the mechanical system to measure vibration amplitude and determines the rotation speed of system resonance to calculate the natural frequency.
This effect cannot be countered by increasing the rigidity of the testing table because the intrinsic property of the table significantly affects the intrinsic property of the CMG.

But on the other hand, the disadvantages are obvious: (1) the pulse signal has a bad impact to the circuit, which can affect the accuracy of the sensor; (2) single type of excitation limits the change of the impedance; (3) frequency of the excitation signal is single, which is not conducive to fully enhance the sensitivity of GMI sensors in different environment and eliminate the possible multivalent.
However, when the magnetic field outside is zero, the curve is mixed with the non-zero curve, which would adversely affects the measurement results.
Reference [6] notes that using what kind of incentive depends on the magnetic properties of the material itself.

According to this resistance strain effect, if a metal conductor is subjected to an external loading, its mechanical deformation will occur and lead to the corresponding change of its resistance.
