This paper dealt with the fabricating process of liquid phase sintered (LPS) SiC ceramics containing the oxide additives of Al2O3 and Y2O3, in conjunction with the evaluation of their mechanical properties.
The oxide additive materials such as Al2O3, Y2O3, CaO and SiO2 were used for the improvement of sintering density and the reduction of sintering temperature in the production of LPS-SiC ceramics. [6-8] The induction of submicrosize or nanosize SiC particle for the control of grain size is tried to improve the mechanical properties of LPS-SiC ceramics. [5] The purpose of present study is to investigate the effect of composition ratio of additives (Al2O3/ Y2O3) on the characterization of LPS-SiC ceramics, in conjunction with the detailed analysis of their microstructure and mechanical property.
Fig. 1 shows the effect of additive composition ratio (Al2O3/Y2O3) on the mechanical properties of LPS-SiC ceramics.

In addition to the modulus of the sabot material, the forward diameter of the sabot and obturator material properties affect the projectile performance [15] and those may affect the stress of the penetrator rod.
Material properties used in analysis are described in Table 1.
As mechanical properties of the sabot are assumed to affect the stress of the penetrator rod, the analysis was performed with variation of modulus of the sabot.
However, as the obturator material properties had little effect on the ballistic performance, the property listed in Table 1 was used.
As studies combined those factors are very few, this study performed to identify combined effects of those factors on the stress of the rod.

OPMF Mechanical Properties Mechanical properties of OPFM composites highly depend on various aspects such as interface adhesion between fiber and polymer, physical properties of OPMF and strength of fiber.
NaOH treatment on mesocarp fiber had influenced the mechanical properties of composite [1].
Hence, that explains the improved mechanical properties of SHS treated bio composite.
Moreover, fiber loading also affects the mechanical properties of OPMF/PP and SHS-OPMF/PP bio composite.

These factors made the effect of suppression dominant.
There were many factors that affected the machining results as the earlier analysis.
They could be attributed to three categories, abrasive characteristics, fluid properties and machining material properties.
The factors mentioned above were not isolated and influenced each other.
The precondition of the achievement was the establishment of theoretical model of chemical corrosion rate and mechanical action model under the influence of many major factors.

Nitrofurantoin was crystallized from multiple mixtures of water and organic solvents with and without additives in order to find and identify factors affecting phase obtained in crystallization and provide possible information on crystallization control.
Although both hydrates are prepared by slow evaporation from acetone/water mixtures [2] there is lack of information describing conditions affecting formation of given hydrates.
Therefore, in this work it was decided to try to find and identify factors affecting phase obtained in the crystallization and gain information on possible crystallization control.
Based on the similarity in the properties it is believed that similar bonding is present in SNMP and SDMF II, although crystal structures of SNMP and SDMF II have not been determined.

Analysis of the factors affecting wear reliability of high speed steel taps with cryogenic.
Researches of the factors affecting the wear volume of cryogenic tap also study the factors influencing the reliability life of cryogenic tap, based OMG three equations: Eq.1 dealing with the connection between HSS life and its wear, Eq.5 and Eq.6 explaining the relation of wear life parameters of cryogenic tap to max wear volume distribution.

Factors Influencing the Mixing Process of Electrode.
Slurry in the actual production, the factors influencing the mixing process of electrode slurry are very much and complex.
This shows that the factors affecting the electrode slurry mixing process are fairly much and complex.
Time variability exists among these factors in varying degrees.
Fuzzy Control in the Electrode slurry Mixing System As the factors which affect the slurry viscosity and homogeneity are complex, it is difficult to determine the optimum mixing conditions, such as the best mixing time and the best paddle speed, in the electrode slurry mixing process.

Factors controlling development of cracks in the coating are poorly understood, and predictions of coating lifetime approximate.
Strain in the coatings is one of the contributing factors affecting the durability.
In this work, the fatigue properties of two types of filled epoxy coatings are investigated under strain-controlled fatigue tests.
The aim of this study is to develop understanding of the cracking behaviour of coating material and the effects of substrate properties on the cracking behaviour.
The fatigue property of the substrate prevents a characterisation of coating fatigue properties in a wider strain range.
