Consequently, cermets with finer microstructure and better mechanical properties can be obtained [4-6].
This seems to provide a better mechanical performance [7].However, reports on the effect of Mo content on the microstructure and mechanical properties of cermets based in Ti(C,N) materials are almost inexistent.
Actually, the flexural strength is the most affected property.
However, this stability may be affected by several factors.

The excellent mechanical properties of carbon nanotubes (CNTs) and nano silicon carbide (SiC) make them ideally suited as filler for reinforcing polymer composites.
The efficiency of reinforcement depends on different factors such as the filler aspect ratio, the filler mechanical properties, and the adhesion between the matrix and the filler [2].
Results and Discussion Fig. 1 depicts the mechanical properties of the composites with various contents of hybrid filler.
The efficient application of hybrid filler system in the mechanical properties of TPNR composite is due to enhanced net work induced by hybrid shape fillers.

The second significant effect of an increased hygrothermal condition is the degradation of the mechanical properties of a PMC ply.
It is observed from various studies that the exposure to high moisture and temperature do not significantly affect the fiber related properties, but, the matrix properties get affected considerably.
The stiffness properties of the constituents are degraded.
It is assumed that only matrix properties are affected by temperature change and moisture content.

The use of these polymers led to the demand for thorough knowledge of their composition and mechanical properties of polymers [4].
The mechanical properties that characterize it are high impact resistance, toughness, stability under load with limited loads, etc.
In addition to the satisfactory mechanical properties of ABS, various improvements have been made to modify ABS properties such as impact resistance, toughness, and heat resistance [6].
Apart from the modification of the material itself (doping), to improve the mechanical properties, it was determined that they are influenced by other factors such as: the thickness of the print layer, the temperature of the substrate, the temperature of the filament, the speed of the print, etc. [7-11].

The properties of the anodic oxide film would be optimized when the parameters were appropriately controlled.
Introduction Ti-6Al-4V has been widely used as dental implant materials due to their good mechanical properties, high corrosion resistance and excellent biocompatibility [1-2].
The result in operating at elevated current density and higher concentration of saturated MCPM electrolyte would affect to the properties of anodic oxide film which showed the better surface roughness and hydrophilicity to the film.
Both the increased roughness and altered chemical species at the surface of the Ti-6Al-4V alloy following anodization are likely to be crucial factors in the enhanced hydrophilicity of the anodized film.

Cryogenic treatment or cryoprocessing is the process of deep-freezing materials at cryogenic temperatures to enhance the mechanical and physical properties of materials being treated.
As a supplementary process to conventional heat treatment process, it provides a novel route for people to enhance the properties of the cutting tool materials and increase the service life of tools.
