Improvements in the mechanical properties up to 15% SiCp was observed.
A key feature of the FDM process is its potential to fabricate parts with locally controlled properties such as porosity, density and mechanical properties [22].
Both were compared and the differences in solidification time and its affect on metal properties of the casting were reviewed.
The results indicate that the sand grain fineness number and amplitude of vibration were the control factors.
These factors affect both the mean and the variation of the bulk density of the V-process mould.

But for the mechanical properties of timber, which in compression, span and structure form is restricted.
In order to make up for the inadequacy of mechanical properties of timber, the field of timber structure usually considers the composite structure in the design, the TCC structure is one of the common composite structure.
The experimental results show that the rectangular notch and triangular notches have high rigidity and shear capacity, and the main factors affecting the effects of connection are the length of the notch and the type of nail.
Due to the above several methods of shear connection need a drill hole or excavated and weaken the mechanical properties of timber beam.
Factors affecting the effects of this kind of connection are the binder viscosity, the thickness of the adhesive and the production process of concrete (precast or in sight).

It necessitates a heat treatment process for improving mechanical properties [8,9].
Result and discussion Mechanical and physical properties were influenced on the particle size.
Therefore, some of mechanical and physical properties have been studied in this paper.

The mechanical properties of Low Carbon Si-Mn Q&P steel are strongly affected by the conditions of heat treatment.
At the same time, the relationship between mechanical properties and microstructure was analyzed.
Q&P steel’s heat treatment technology was analyzed by microstructure and mechanical properties.
Microstructure Observation and Experiment Result Analysis Mechanical properties.
It is shown that partitioning temperature and holding time have a strong effect on the mechanical properties.

Dual phase and complex phase steels are under investigation to examine the effect of thermo-mechanical processing parameters on local ageing ability and its use for designed properties.
The ageing of steel is a process by which the mechanical properties of the material change over time.
Using bent metal sheets, it was investigated to what extent factors, such as true strain, bending radius and bending angle influence the BH effect and how to determine them most efficiently.
To evaluate the effects on mechanical properties tensile test were conducted.
The change of mechanical properties by LHT was checked by tension test using photogrammetric deformation analysis ARAMIS by GOM and finally local strengthening by LD was accompanied by FEM simulation.

It is known that the mechanical and physical properties of the materials are affected by a number of factors, such as the volume fraction of biomass powders, dispersion level, biomass polymer matrix adhesion, mixing time and processing temperature [5].
Composite charactizations Mechanical Properties.
The mechanical properties of the wheat straw flour/polyethylene composites were estimated via tensile, flexural, and impact properties.
Mechanical Properties.
The Mechanical properties for different MAPE content are listed in Table 2.

High hardness and withstands wear are important properties and also has relatively high resistance to shock.
So, there are several factors affected to quality of surface such as Power setting, Off time off, Wire feeding, Wire tension and Wire offset.
The ANOVA was showed that the main factors affect to response is only power setting as shown in Table 5.

Ti-based coating has been used for biomaterials to improve biocompatibility, mechanical and corrosion properties.
Each coating shows unique performance depending on a variety of factors such as coating microstructure and properties as well as in-service conditions.
Many factors such as the overheating of the target, arc spot travel, deposition rate, and bias voltage characteristic can affect the growth of defects due to the change in energy level of ions, which can affect adatom mobility and surface diffusion [14-16].
However, these voids and particles could affect surface coating properties such as flow resistance, crack initiation and propagation resistance.

These defects can limit the performance of a welded pipe, and their impact on mechanical properties must be comprehended to ensure safe pipeline operation [5].
Hydrogen may cause degradation of the mechanical properties under specified load condition known as hydrogen assisted cracking [6, 7].
Due to a wide range of parameters affecting the HAC phenomenon (Fig. 2.) besides the tree main factors (such as the rate and mode of loading, constraint conditions, hydrogen charging method, temperature, specimen size, diverse microstructural factors, etc.) the outcomes of conventional HAC tests demonstrate a large scatter [16-19].
Schematic representation of various factors influencing HAC [16].
The samples were not heated up to 250 °C, because in some cases (e.g. high strength steels) the material manufacturers do not guarantee the mechanical properties of the material when heating the piece up to this temperature.
