The width of precipitate free zones (PFZs) has been found to be one of the factors affecting the fatigue life of the specimens at 423K.
Tensile properties were determined with an initial strain rate of 3.0 x 10-3 s-1.
Results and Discussion Mechanical Properties.
In the addition to the difference in Al3Sc particle sizes as mentioned above, the existence of PFZs can be pointed out as another factor affecting fatigue life.

The purpose of the present study is to clarify which characteristics of the fine wire drawing process contribute to these superior mechanical and metallurgical properties.
To determine the origin of the combination of high strength and high ductility, several factors are considered.
It is believed that the physical properties of fine wires are different from those of thicker wires.
As shown in Fig.7, three factors contributed to the drawing stress .
Several factors were proposed as the cause of this phenomenon.

The mechanical properties of 3D printed materials in FFF technology depends on various parameters and the literature suggests that infill pattern and infill density are the parameters that most affect the mechanical properties of 3D printed parts.
In this context, 3D printers can use a wide variety of materials with different mechanical properties, visual appearance and finishing precision [3].
The mechanical and physical properties of PETG filament are presented in table 1.
All factors and their levels can be seen in Table 4.

Also, Vaishnav et al [8] used Solidworks software to model various factors affecting thermal performance of fins using the length, area covered and the geometry of the fin, and the result indicated that there was substantial effect on the thermal performance when the shape of the fin was changed compared to when the length was changed.
Additionally, applying the FVM facilitates handling the nonlinearities arising from temperature-dependent properties.
In Fig 8, The scale factor, ∈2, primarily influences the temperature distribution pattern along the fin length, without significantly affecting the overfall temperature drop.
This insight gained can guide the optimization of the selection of fin geometries and material properties for various thermal applications.
This approach stands in contrast to other numerical approaches that rely on assumptions of constant thermal properties.

The quality of the shearing edging of blanking parts was used to evaluate the different influence degree of three factors.
However, the too fast deformation speed will not only affect metal plastic property, but also produce temperature effect.
It is made up of three affection factors and three levels.
Three affection factors include blanking clearance, blanking speed and the die surface roughness.
The result shows that the optimum scheme is A1B1C1, and the die surface roughness affects the quality of the shearing edging more than other two factors.

The influence of thermal cycling treatment of pseudo-α-titanium alloys OT4 and VT20 on their structural and substructural characteristics, as well as their mechanical properties is considered.
This contributes to an increase in the strength properties of alloys with satisfactory ductility and high-temperature strength.
The temperature range of thermal cycling, depending on the purpose of the hardened product, on the physical and mechanical properties of the material and its initial structural state, is selected.
These parameters affect the features of the formation of the structure and properties of pseudo-α-titanium alloys in the course of thermal cycling exposure to them.

In the process of machining, one of the main factors affecting machining tool wear is friction.
Introduction In the scope of the current work, it is proposed to use dummy variables for an assessment of a large number of attributive factors characterising friction.
Also, a significant outcome of this study is the determination of coefficients characterising the impact of each factor on the result separately and an opportunity of ranking the factors by the level of its impact on the outcome variable.

A mathematical model is obtained in the form of a differential equation of mass transfer, which takes into account the physic and mechanical composition of the dust emission from the ventilation shaft of the coal mine as a factor of ecological hazard.
At the same time, one of the factors that determine the environmental hazard of the coal mine operation is the physic and mechanical composition of the dust emission into the atmosphere from its main ventilation shaft [17, 18].
This is consistent with the results obtained on the mathematical model in the form of a differential equation of mass transfer, which takes into account the physic and mechanical composition of the dust emission from the ventilation shaft of the coal mine as a factor of environmental hazard.
