Introduction Durability of dies is one of the most important factors affecting the cost of hot forging products and is in the range of 5 to 30% of the cost [1].
The tool life evaluation has been done using the same mechanical properties of the steel H13 as in the first example of bevel gear forging.
The elastic properties during cyclic loading for steel H13 are published in work [10] and critical plastic strain is approximated using the results of investigation in [18].
Meanwhile despite of limited amount of important experimental information regarding properties of the tool steel, the approach for quantitative estimation the tool life of the dies in hot and cold forging is possible as shown in this paper.

PVDF has good piezoelectric properties and has excellent mechanical strength while retaining flexibility.
The physical and piezoelectric properties of the energy harvester are outlined in Table 1.
The area around the damage location was found to be severely affected, as was expected at the beginning of the investigation.
This proved to be a factor of the order of 0.06.
As can be seen in the figure, all other regions had a factor of between 1.16 and 0.93.

They undergo devitrification occurring under effect of external factors, which results in the decrease of their hydrolytic stability and the radionuclide release.
A unique set of physical–chemical, radiation–physical, and mechanical properties of ceramic radionuclide matrices fabricated in accordance with the SPS technology determines their excellent functioning characteristics, which was demonstrated in [10,11] and other works.
It was determined that high-temperature phase transitions during SPS sintering of NaA zeolite affected physical–mechanical properties of the fabricated samples of ceramic and glass ceramic matrices.
It has been revealed that the required physical–chemical and physical–mechanical matrix properties are achieved as a result of solid-phase changes during the SPS treatment induced by phase transitions, mechanical and deformation impacts, and thermal effects.

Bamboo mildew fungi feed on the material without cell wall, so it has minor hazards to the cell and also does not affect the strength of bamboo.
These photo-electrons and holes have superior redox capacity which can kill many bacteria and viruses, and they also are qualified by wide range of antibacterial spectrum, good heat resistance, excellent antibacterial effect and so on, which may significantly improve the anti-bacterium and anti-mold properties of material.
At the same time, they characterize the form and structure of TiO2 by using NMR, FESEM, XRD and EDAX, and focus on studying the influence of temperature on the morphology, the crystal form and the anti-bacterium and anti-mold properties of TiO2 film.
The future research direction of the anti-mold and anti-corrosion of bamboo timber will focus on the development of new, green, highly effectively and inexpensive mold preservatives, which mainly includes anti-mold and anti-corrosion effect, durability, cost, environmental protection, anti-loss, the influence on the physical and mechanical properties of plates and so on.

Particle diameters are characterized by laser particle size analyzer, and the effect of different factors on the particle diameters is discussed, respectively.
In addition, it is also used in the electronics, medical and sugar refining industry, the oil additives for its anti-corrosion and desulfurization property, the thermal insulation material and the raw material for manufacturing other magnesium salt products [1].
Recently, the particle diameter control of magnesium salt powders has attracted much attention and becomes an interesting topic in the field of flame retardants, because the particle size possesses very important influences on various chemical and physical properties of flame retardants [3-5].
The experimental results indicate that the aging time is also able to affect the particle diameters of magnesium salt powders obviously.
Thus the mechanical performance of the materials can still meet the requirement by adding enough magnesium salt flame retardants.
