In the last 20 years, the granular magnetic recording media was rapidly developed and one of the important keys is the understanding of magnetization reversal in individual grain or element [5,6].

The technical result of the development is a simplification and economic benefit due to a smaller number of a technological method for producing powdered aromatic PEEK, convenient for washing from solvent and salts, and convenience for unloading from the reaction vessel.
Fine-grained polyarylene ether ketone powder.

Hydrogen has the smallest atomic size among all the elements and diffuses rapidly even at room temperature and accumulates at the microstructural defects such as voids, dislocations, grain boundaries, precipitates and triple junctions [4].
Acknowledgements This research was supported by the PRODEP, project number DSA/103.5/16/10908 for UPVMEX-PTC-095 and UPVMEX-PTC-097 .

Filtering method also proposed to reduce the number of unrelated documents such as XFilter, YFilter, XTrie [4].
Background XML based Publish/Subscribe system can express more and satisfy subscribers’ fine-grained interest.

In the process of drawing, grains are stretched along the drawing direction, causing work hardening.
With the annealing temperature rising, a large number of Ni2Si particles precipitates in Cu-Ni-Si alloy, which increases the strength of composite wires.

The kinetics Avrami-equations of phase transformation can be expressed as follow: f=1-exp(-btn) (4) Where f is volume fraction of precipitates; t is aging time, b and n are constants. b depends on the temperature of phase transformation, composition of supersaturated solid solution and size of crystal grain. n depends on the type of phase transformation and nucleation location.
A high dislocation density gives a large number of nucleation sites, and therefore a faster rate of precipitation and growth.

Sun et al. have identified that the AZ91 alloy, to which Ca was added, contributes to the grain refinement and enhances elevated temperature properties [9].
Acknowledgment “This work was supported by a grant of the Romanian Ministery of Research and Innovation, CCCDI – UEFISCDI, project number PN-III-P1-1.2-PCCDI-2017-0239/60PCCDI 2018, within PNCDI III”.

Their good engineering performance has led to an increase in the number of their applications, mainly in corrosive environments, such as sour gas pipelines and chemical reaction vessels.
Ferrite grain growth of the steel is hardly observed [3].

The number of grains contained in this volume was estimated at 6 x 104.
