Treating time at 650 °C was a main factor determining microstructures and properties of the composites.
Mechanical tests were performed on the materials with different microstructures to establish their properties and fracture behavior.
These factors increase the cost of component production and make the application of these composites economically unattractive.
Mechanical tests were performed on the Ti-(Al3Ti+Al) and Ti-Al3Ti composites to compare their mechanical properties.
Table 2 summarizes the mechanical properties of the laminated composites.

And the material properties can affect the performance of seal ring directly.
The experimental results indicate that the amount of reclaimed rubber added into the seal ring has significant effect on the physical and mechanical properties of the blend.
Therefore, available from Table 3, the blend ratio is the main factor affecting the tensile properties, followed by silica, DCP and curing temperature, and excellent combination is A3B4C2D3.

Dissimilar Friction Stir Welds in AA 5086–AA 2024: The Effect of Process Parameters on Microstructures and Mechanical Properties S.
The effect of tool traverse and rotation speeds on the microstructures and mechanical properties are quantified for welds between non-age-hardening Al5083 and age hardening Al2024 and compared to single alloy joints made from each of the two constituents.
It was found that the weld properties were dominated by the thermal input rather than the mechanical deformation by the tool.
The effects of variations of traverse and rotation speed on the mechanical and microstructure properties of joint are investigated.
These factors are the main factors which affect the heat input.

Lack of this understanding and a set of reliable structure-property relationships are currently the major factors impeding wider applications of this class of composites.
In presenting this initial data, no attempt has yet been made to censor the data based on the factors mentioned in the preceding paragraph that may adversely affect the mechanical properties.
Further analyses of the raw data are underway to refine and compare the properties of the twelve types of specimens with factors that influence the results in the background.
Factors that affect the properties are identified for further data reduction and analyses.
Through these studies, it has become clear that many factors affect the mechanical properties ranging from preform and composite fabrication through testing and rational data reduction.

Highlighting the significance of correlating the laying pattern to their mechanical properties, determining the properties of fabricated components may play a crucial role [6,7].
Comprehending to the facts that improper FDM processing parameters setting, inappropriate filament material selection, bad part design and topology, could negatively affect the final mechanical properties or the aesthetic appearance of the 3D printed part, therefore, it is of utmost importance to effectively control all the influential factors to improve the quality characteristics of the final 3D printed part, which in this case is hollow and thin-walled structures.
Table 1 lists the general properties of pure PLA granules.
The selected factors and their levels are shown in Table 2.
From Table 4, the topology design appears to be the most decisive factors in enhancing the compression properties of the 3D printed hollow and thin-walled structures with the percentage of contribution of 29.998% followed by wall thickness, layer of thickness and density.
