Waspaloy is a γ' strengthened nickel-base superalloy that is used for manufacturing gas turbine engine rotors and disks, due to its good high temperature mechanical properties and corrosion resistance too[2].
However, the negative effect is that some brittle intermetallic compounds are generated and decrease the mechanical properties[5].
The brazing quality is influenced by many factors including brazing temperature, filler metal thickness, holding time, cooling rate, etc.
The brazing temperature and the brazing clearance mainly affect the amount of solid solution and the microstructure of brazing joint.
Lower microhardness of the solidified zone nearby the brazing affected zone might be attributed to the absence of intermetallics and the presence of high performance solid solution.

With composite specimens as cathodes and increasing electrode distances, the composites are severely damaged due to serious sparks whose formation are affected by the geometry of electrode setups.
Associated with a strong electrical, magnetic turbulence and a mechanical collision, the arc severely damages the contact materials [2].
Thus, a high strength and good wear resistance, high electrical and thermal conductivity, and good chemical stability are required properties for good contact materials [2-4].
However, no researche regarding the arc erosion behavior of short fiber reinforced composites have been performed though they exhibit better properties and are predicted to have different arc erosion behavior [7].
The damages of composite materials caused by spark erosion are basically dominated by three factors: (1) solid-state wear, (2) liquid formation, and (3) liquid flow [8-11].

As well known, poly(lactic acid) has better potential of mechanical properties [1].
In biomedical application, poly(lactic acid) has been widely applied by considering of its mechanical properties as bone screw, scaffolds material and suture [2-3].
Enhancement of mechanical properties as well as degree of crystallinity of poly(lactic acid) can be obtained by this method.
Finally, weight lost of composites and pH values of PBS solution were documented at each time and then degraded composites were analyzed their thermal properties, thermal stability and morphology.
Characterizations Thermal properties of the materials were analyzed by DSC60 (Shimadzu, Japan).

Development of Nonlinear Analytical Models for the Study of Heat/Mass Transfer Properties in the Drying of Porous Type Fabric Ralph W.L.
Relationships between the model parameters and fabric physical properties were determined for further used in the design of drying equipment.
The model principle of the First order kinetic is an assumption that vaporization of bounded water is a dominating factor affecting the moisture removal rate at the falling rate period.
The model equation is given as: Table 1 - Textile properties of the tested fabric samples.
However, regression model has considered the air velocity properties that have not been included in the Arrhenius equation.

The physiochemical properties of the developed adsorbents were evaluated.
To upgrade or improve the adsorption properties of the RH, thermal treatment of rice husk has been established.
Factors affecting sorption, such as contact time and pH were investigated.
The kinetics of the adsorption of phenol was studied in batch experiment by using a GFL mechanical shaker (3017).
In order to compare the textural properties of adsorbents, the parameter obtained from BET surface area, pore volume and pore diameter are tabulated in Table 2.

The wide use of titanium in many areas of industry is explained by high set of its physical and mechanical properties, particularly by high specific strength and phenomenal corrosion resistance.
Nevertheless, even more stringent requirements to materials properties are required in some fields of industry.
However the widespread use of tantalum is limited by several factors, mainly its high cost and low production volumes.
Authors of [3] note that alloys of titanium and tantalum are the most promising for nuclear waste processing plants, when it is important to take into account corrosion resistance, mechanical properties, availability and cost of material.
At least three clearly separated zones can be marked out in the cladding structure: a zone of a melted metal (1), a heat affected zone (2) and an unaffected zone (3).

The fundamental properties of snow and ice, the main winter objects’ attribute, are studied by engineering glaciology, therefore, already developed knowledge in this area is used in the design of complexes for winter sports.
The physical and mechanical snow properties (as a material) are determined by objective indicators: density, hardness, connectivity, frictional properties, adhesion and freezing, moisture, snow structure and texture.

Welding residual stress is a consequence that is led to many factors.
Being heated uneven locally in welding process is the major factor that arouses welding residual stress.
And it could improve several factors that would influence the weld fatigue strength at the same time [2].
The residual stress gets released, and the mechanical properties of materials get improved [6-9].
