High mechanical compression and energy source induces a significant alteration of physicochemical properties of solid pharmaceutical crystal (2).
Furthermore, the effect of crystal lattice structure on mechanical properties on single and poly-crystalline is needed to understand crystal lattice behavior under compression (1).
At the molecular level, intermolecular interactions such as hydrogen bonding and van der Waals interactions were the key factors that are actually responsible for the behavior of molecular crystals.

The film properties and morphology were investigated and analyzed.
Two major film properties were used to examine anti-sticking characteristics.
To determine the injection parameter, the hold pressure was fixed at 70 MPa, while other control factors were as mentioned above.
The factors affecting wear resistance included: coefficient of friction, hardness, adhesion, and chemical stability.

During welding various defects may occur in areas of welds, heat affected zone and weld metal, e. g. gas cavity, welding slag, incomplete fusion or cracks.
Moreover, the individual factors are frequently multiplied, which increases the total risk of rail failure.
This change in the microstructure and thus also the local properties in the foot of the rail immediately at the surface can be considered as a crucial finding of the analyses.
The transition area between the transformed and the original microstructures ten had the nature corresponding to the heat affected zone typical for the weld joints.
Any other factors having the origin in metallurgical quality, material properties and/or surface defects were not determined.

The mode of accelerated curing on mechanical properties of the GGBS based concrete for various mixes of concrete was investigated systematically.
Several experimental studies conducted evaluates the hardened concrete strength and strength efficiency factors by replacing the cement by various percentages of slag.
Temperature and water to cement ratio are two important factors that affects the setting time of concrete [3].

Electro-Spark deposition of composite TiB2-TiC on electrodes’ surface Fenfang Tan1,a, Ping Luo2,b, Zhixiong Xie2,c 1School of Mechanical Engineering,Wuhan Polytechnic University,Wuhan 430023, PR China 2School of Mechanical Engineering, Hubei University Of Technology, Hubei, 430068 PR China aTanyi8447@126.com, bblueknight_0930@163.com, cshebu@126.com Keyword: Electro-Spark; Coated electrodes; TiB2-TiC; Resistance spot welding Abstract.
These coatings have their unique set of properties, for example only TiB2 and TiC coating layer have bad wetting with the substrate of Cr-Zr-Cu, Ni/(TiCP/Ni)/Ni multi-layer has bad stability in high temperature conditions, these defects of coating will badly limit the prolong of life of coating electrodes.TiB2-TiC composite coating can resolve these problems.
In the system, there are two important factors will affect quality of the coating layer, the first is voltage, the second is the value of capacitance.
Fig.5 shown capacitances also will affect quality of coating layer, but it is not primary.
This paper first discussed coating parameters affected for the quality of coating layer, and first using secure voltage (<36v) during ESD process.

Introduction It’s very important to evaluate the mechanical properties of the subgrade of pavement while the load-pavement-subgrade system is an interaction system.
The depth of subgrade affects the subgrade frequency greatly according to the laboratory model analysis.
Calculation method of influence depth Aircraft load and gravity affect the subgrade.
Through calculation, the dowels between the pavement plates have less affected to frequency of overall pavement.
Wei etc: Research on influential depth of vehicle loads and its influencing factors.

Introduction Owing to its excellent mechanical properties, biocompatibillity, biodegradability, and bioresorbability magnesium is regarded as a promising biomaterial for use in porous scaffolds that are employed in tissue engineering applications [1].
Alloying is one of the most effective methods for modifying the properties of magnesium.
Zinc is an essential element for the immune system and for maintaining the co-factor for specific enzymes in bones and cartilage [5,10].
This increase in turn affects the solid solution strengthening of zinc in magnesium matrix.

The wear properties of the mandrels change as the plugging process occurred under various initial conditions.
Despite the high number of carried out experimental works, assessing the influence of technological factors on the metal sliding in the deformation zone and the wear of the mandrels during screw rolling is still hard.
The research object of this work is a plugging mandrel, which has been assigned the properties of X38CrMoV5-1 steel (0.4% C, 5%Cr, 1.5% Mo, 1% V).
The mechanical properties of materials have been extracted from the software’s database.
The wear rate of the tool is conventionally defined as the lost volume on the surface per unit of the metal distance traveled, is a function of many factors, including the normal force F acting on the sliding surface, their metal sliding Vi, temperature T, as well as material thermal, mechanical, and physical properties [16].

However, the inherent degradability of these additives lowers the mechanical properties of the blend and results to accelerated and uncontrolled degradation of PE film.
Results and Discussion Tensile Properties.
ANOVA shows that all factors significantly affect the tensile strength of exposed films.
