This alloy system has several interesting properties for solder applications, namely, the low melting point, similar to the Sn-Pb alloys, and good mechanical properties [2,5].
The reliability of a solder joint is affected by the solder substrate interaction and by the solder mechanical properties [5,6].
The microstructure type and phase chemical composition are important factors to anticipate the solder mechanical behavior in service.
Mechanical properties obtained in the alloys, in the as-cast and homogenized conditions.

Some factors can affect the experimental results of sandglass extrusion, such as extrusion ratio, number of extrusion, extrusion temperature, friction and free space in mould cavity etc.
These factors have different effects on material microstructures, properties and defects.
Wang designed a set of mould and relative technology called "sandglass extrusion" (SE) (because the shape of mould cavity looks like a sandglass), then investigated the method, the development of the microstructures, the mechanical and superplastic properties of the material treated by SE [7-9] with present authors.
Some factors can affect the experimental results of SE, such as extrusion ratio, number of extrusion, extrusion temperature, friction and free space in mould cavity etc.
These factors have different effects on material microstructure, properties and defects.

The addition of MCC to cement-stabilized soil resulted in a reduction in hydraulic conductivity due to its water absorption properties, although it did not significantly improve mechanical properties.
Overall, while MCC alone had limited impact on mechanical properties, SB emulsion showed promise for enhancing toughness and ductility.
This study aims to investigate the potential of MCC to enhance the mechanical properties of SB modified cement-stabilized soils.
Several factors could contribute to this phenomenon.
The addition of MCC to cement-stabilized soil resulted in reduced hydraulic conductivity due to its water absorption properties, but did not significantly enhance mechanical properties.

These three milling conditions all affected the B2O3 activity more or less, as evidenced by the changes of B2O3 activity with these milling factors.
In addition to those influencing factors, the mass ratio of balls to sample, the diameter of milling balls, and filling ratio of samples also have significant effects on the physicochemical properties and activity of the products [8,11].

Once plasticized, the starch performed better mechanical properties and reduced fragility.
As mentioned by Bahrololoumi et. al. (2021) that aging process can lead to changes in the material's physical, chemical, and mechanical properties, affecting its performance and durability [8].
Mechanical properties were evaluated for both unaged and aged samples, with acceptable tensile properties observed.
The study also examined weight loss degradation under heat, identifying factors that contributed to improved properties compared to the Control TPS.

Qiub School of Materials Science and Engineering Shenyang University of Technology, Shenyang 110870, China aYjb97522@sohu.com, bkqqiu@yahoo.com.cn Keywords: AZ91 composites; steel web reinforcement; mechanical properties; slip bands activation Abstract.
The mechanical properties of the resultant composites were much improved in regarding to the elastic modulus, 0.2% offset yield strength, ultimate compressive strength and the strains compared to the unreinforced counterpart.
The interaction between the web and the dislocations in the matrix and the load transfer from the matrix to the reinforcement are the strengthening factors.
However, they showed limited success in improving the overall mechanical properties, especially the plasticity due to the high brittleness of ceramic-Mg formulations.
The mechanical properties for the materials discussed are summarized in Table 1.

The key factor affecting life of progressing cavity pumping system is the rotor speed.
Taken these parameters as original inputs, the nonlinear mapping relationship between rotor’s rotational speed and its affecting factors are determined by means of artificial neural network, and establish the output speed prediction model.
Screw pump speed was mainly governed by the following factors: (1) Temperature affect on speed Fig.1 Temperature affect on speed Because screw pump stator rubber liner has obvious properties of heat bilges cold shrink.
(2) Oil viscosity affect of speed Fig.2 Oil viscosity affect of speed Oil viscosity is one of the larger factors influenced on screw speed.
Conclusions Based on the experimental data of ESPCP system, this article use the artificial neutral network method to establish the optimization model that between the output speed and its affecting factors.

Because polymers offer attractive mechanical and chemical properties, polymers are becoming the most promising materials for the microfludic devices [3].
As one of polymers PMMA has been particularly useful for microfluidic chips because of the features of low price, excellent optic transparency, and excellent electric and mechanical properties.
Thermal bonding processing parameters depend on the polymer's viscoelastic property.
The factors of affecting the bonding process have three parameters.
Because the temperature is main factor affecting the bonding quality, lots of bonding experiment was completed from 60°C to 100°C.
