Introduction Ultrafine-grained materials have been studied by many scholars due to their excellent physical and mechanical properties.
This is an important process for a material’s microstructure and mechanical properties.
Therefore, these two factors make recrystallization more likely to occur.
Thus, for some metal materials, within a certain temperature range, the temperature will affect flow properties.
Therefore, deformation at a relative lower temperature and an appropriate speed is increased the material’s mechanical properties.

Therefore, depending on the origin and physical properties of the silica, composites of same filler type and same matrix type with different properties are possible.
A comparison on mechanical properties, and morphologies of these three types of composites were carried out.

The sintered samples were analysed in order to consider the properties of SS 316 L foam after sintering process.
The space holder particles have a low melting or dissociation point in stainless steel, which affects the foaming process and the resultant mechanical properties adversely.
Lastly, the sintering parameter also plays a serious factor to fabricate the proper SS 316 L foams.

Starting with the necessity to identify the optimum values of the cutting parameters which are affecting the surface quality, it is appropriate to use the design of experiment techniques to conduct the experiments.
The orthogonal matrix includes these three factors set for analysis, each with 2 levels associated.
So, in this research, the attention will focus on aluminum alloys whose properties are superior to other materials.
Taguchi calls this variability - noise factors [5]; the strategy he uses is not to control these factors (which sometimes can be expensive), but instead to minimize their impact.
Concerning my research, the process parameter combinations (cutting speed, depth of cut and feed per tooth, hereinafter referred to as control factors), will be determined with the purpose of reducing the effects of noise factors rather than focusing on their root case.

Soğanci et al. [6] assessed how marble dust (MD) and granulated blast furnace slag (GBFS) affect the geotechnical properties of low and high-plasticity clays.
Additionally, the inclusion of 4 to 10% cement significantly enhances the mechanical properties of unfired earth bricks compared to those lacking cement [15].
Effect of Stabilization Percentages on Consistency Limits The results in Fig. 5 revealed that the lime stabilization reduced both the plastic limit and liquid limit of the clay, therefore, affecting the plasticity index.

Complex Change in Superficial Layer Properties of Specimen Obtained by Metallurgical Powder under Vibration Process Method Khaled Hamouda 1, a, T.
The principle of the process depends on the properties of a work-piece, which is affected by the environment and mechanical behavior, or mechanical operation by the smallest particles, smoothing of its micro-roughness and plastic deformation of a superficial layer.
Also the process conditions can be summarized by: modes of vibration, characteristic of the process, coating technology and mechanical properties of the specimen.
The role of temperature is not limited by the decrease in resistance of a material to the plastic deformation and mechanical properties of metals and alloys, also with taking into consideration the temperature effect, a brittle zone will be found as a result of low and moderate degrees of temperature.
Technical properties for the machine with a heat chamber The purpose of the experimental study is featured by forming of an anticorrosion coating metal (aluminum, zinc compositions and their alloys) on preheating the powder materials.

Introduction Molded parts precision, performance and efficiency are the three main factors that slows down the development of RPM, in which the four main factors affecting accuracy of FDM parts can be summarized as follows: ① Errors caused by prototyping system, referring to the localization accuracy and repeatability of localization accuracy of nozzle motion; ② Principle errors caused during the triangulation and slicing process; ③ Errors caused by nozzle with a certain diameter; ④ Errors caused by material shrinkage.
Second, with temperature increasing, it gradually changes to high-elastic state and finally to melted state where it shows rheological property, very important property for FDM process.
Extrusion temperature determines the bonding properties of materials, accumulation property, filament material liquidility and extruded filament width.
However, not a fixed value is the width of extrusion filament, subject to influence of many factors such as nozzle diameter, layer thickness, extrusion speed, scanning speed, extrusion temperature, envelope temperature, coefficient of adhesion, shrinkage rate, and so on.
In addition, there also exist other factors affecting parts accuracy such as principle error, error caused by numerical control system and error caused by material shrinkage etc..

FSP has been successfully applied to various aluminum alloys in order to improve their mechanical properties [4, 5].
In FSW and FSP, the critical process parameters, that could affect the weld quality and mechanical properties, are rotational speed, feed rate, tilt angle, plunge depth and tool design.
