It has been reported that such cracking is caused by hydrogen embrittlement in the degraded structural materials [3,4].
Table 1 Chemical compositions of materials used [mass%]Results and Discussion The crack susceptibility in y-groove weld cracking test and repair welding test was estimated by crosssectional observation after these tests.
Hydrogen distribution in the materials was calculated with using the diffusion equation based on activity, as demonstrated in following equation

In recent years, a serious of new materials and techniques of fire fighting for coal fires have developed in China, for instance, a serious of gel materials and equipments of fire preventing and extinguishing[4,5], and the technology of fire preventing and extinguishing with liquid carbon dioxide[6] have researched by Xi’an University of Science and Technology.
In which technologies of serious of gel materials for fire preventing and extinguishing have promoted to the Russia, India and Bengal, which has yielded highly desirable results.
The technologies of gel materials of fire preventing and extinguishing have capabilities of leakage protection, lower the temperature, retarding coal oxidation and consolidating water.

In order to machining the slit grating, a quadrilateral PCD micro-milling tool is fabricated with CTB002 PCD material (Fig. 2a).
Comparing two machining method, cutting force of flying-cutting are much larger than micro-milling mainly due to the different material removal amount.

In the European Union, the consumption of materials is currently higher than the extraction from the primary raw materials, so most countries depend on the import of metals from other countries of the world.
Approximately 34 % of the world's Zn production comes from recycling materials [1].
The use of recycled raw materials often brings with it the disadvantage of quantitative deviations in chemical composition.
Firstly, it offers access to inexpensive precursor materials, significantly reducing manufacturing costs.
