Hydrogen accumulation in metals may cause damage to the material by also producing fracture, thus limiting operating lifetime.
Darken and Smith proposed that point defects or even extended defects of the material can explain the observed data, as defects can behave as traps attractively interacting with the hydrogen atoms.

It is explained by the fact that existing foundries are equipped mainly with induction melting furnaces of industrial frequency, and the use of induction melting furnaces of medium frequency requires considerable material costs.
Induction furnaces of industrial frequency have high technological flexibility: it is possible to produce cast iron of any chemical composition, to produce liquid metal in arbitrary portions, to store the metal continuously for a long time without changing its properties, to use charge materials of low bulk density and to mechanize the melting processes [5].
· Automatic sintering and cold start programs only work with lining materials supplied by furnace manufacturers
However, the traditional composition of the lining material does not allow the production of an acid lining that withstands high resistance at working melting temperatures above 1450 °C, especially when steel is smelted.

And the mechanism of resistance to chloride ion permeation concerning different mixing proportions of the materials is figured out.
After that, basing on the effects of these materials on the durability life of recycled concrete in chlorate surroundings, the sequence is worked out: first, air entraining and water reducing agent, then recycled coarse aggregate, last one, polypropylene fibre.
The anti chloride ion penetration experiment of RC 1.1 Raw materials In the experiment, the binder is P.O32.5 cement and the sand is plain river sand whose fineness module is 2.9.

When the material is impacted and cracked, the butadiene with characteristics of rubber will release the stress at the crack tip, which hinders the crack propagation, and the impact resistance of the material is greatly improved.
Because of the difference of polymer materials, there are generally differences in the structure of materials, resulting in great differences in mechanical properties and molding properties.
In addition, polymer materials have a variety of unique properties, such as shear thinning, so it is necessary to accurately found the mathematical equations to characterize these properties.
The raw material is mixed sheet ABS 198819 produced by the company Hengrui Plastic Materials (Dongguan, China).
