The markedly improved microstructures and mechanical properties of the fabricated alloys by the D-SSC process were investigated.
Introduction Al-Si based cast alloys are widely used due to their superior castability and excellent mechanical properties.
On the other hand, from the recycle point of view high impurity elements such as iron could negatively affect alloy properties, especially ductility.
Mechanical properties.
In the next step the mechanical properties of the D-SSC specimens were performed.

And the factors were also analyzed, such as wood species, veneer thickness and LVL density.
LVL is a structural material laminated with multiple thick veneers parallel the grain, and exploits a broad space for its development in the area of structural materials for its good mechanical properties.
There are many factors impacting on the ultimate strength of LVL, such as wood species, the thickness of veneer, the density of veneer , mechanical properties of veneer, the type of adhesive, glue spread, hot press process and the thickness of products, etc [2].
Different factors have different levels of effect on the ultimate strength.
This paper only had reliability analysis of the affect the thickness of the veneer on LVL, the reliability level of LVL affected by other influencing factors remain further study.

Experimental results on tensile mechanics properties of GFRP bars at high temperatures are present in this paper.
However, the severe degradation of mechanics properties of FRP at elevate temperatures maybe the crucial barrier for its widely applications.
It can be observed that the mechanical properties of GFRP bars are highly dependent on temperature, and the strength and stiffness exhibited severe reduction at elevate temperatures.
The soften temperature of fibers probably the most important factor which mainly influence the strength of GFRP at elevate temperature.

But as much as it is aimed to produce functional 3D printed components with exemplary mechanical properties, issues with anisotropy and reduced mechanical properties compared to the components produced using the conventional techniques also tend to arise in the FDM technique [11–14].
One of the important factors that dictate the properties of the 3D printed component is the type of materials used.
Mechanical Properties.
This also implies the interfacial bonding within the microstructure of the 3D printed material, which increased the mechanical properties.
The presence of these voids is the primary reason for the decrease in the mechanical properties of the said blend.

Bending tests determine material quality and mechanical properties before winding joints into coils.
Physical Properties of A36.
The mechanical properties of ASTM A36 are listed in Table 2.
Mechanical Properties of A36.
Both trials did not meet the standard tensile strength for A36 steel due to factors like welder procedure and steel machining.

A correlation between the three parameters and the stress-strain properties was specified.
Controllable rheological properties make the MR fluids useful for vibration mitigation devices application.
The estimated factors relationship with the response in this study is given by the following equation.

Conclusion Three parameters for the stress-strain properties were investigated.

So far there are not prediction models of polishing process considering these complex factors above.
The researches on the main factors affecting the material removal rate focus on load, rotary speed and polishing liquid ingredients, but rarely on the evolution of workpiece surface profile and the reasons.
The element type is plane182 and the mechanical properties of the materials and other related parameters are shown in Table 1.

Stainless steels have gained much attention to be an alternative solution for many manufacturing industries due to their high mechanical properties and corrosion resistance.
Stainless steels, considered as difficult to machine materials, are widely used in many fields such as food industry, health, chemical and petrochemical sectors due to their high mechanical properties and excellent corrosion resistance.
Selaimia et al. [10] investigated the effects and optimisation of control factors on surface roughness and cutting forces in a milling operation of the austenitic stainless steel X2CrNi18-9 (AISI 304L) using RSM and desirability approach.
The results showed that the cutting time is the dominant factor affecting workpiece surface roughness followed by feed rate.
It can be concluded that the depth of cut (ap) is the most important factor affecting the Fz with 62.12 % of contribution followed by feed rate with 35.23% of contribution [12,17].

Introduction 7A52 Al alloy is extensively used in maritime facilities on account of the high strength and easy-welding properties [1-3].
Therefore, the welding technology is one of the critical factors affecting the behavior of the welding structure [7-9].
The SCC susceptibility was evaluated using mechanical properties such elongation to failure (δ), reduction in area (Ψ) and ultimate tensile strength (σ) as measured in air and in cycling seawater.
According to a research work [10], a handful of β-MgZn2 which is strengthening phase was produced in the weld zone, that is the important reason for the loss in mechanical properties of TMW 7A52 Al alloy.
